Abstract
Description
- This application depends from and claims the benefit of U.S. Provisional Patent Application No. 61/155,601 filed on Feb. 26, 2009.
- This application relates to the drilling of an earthen bore, cementing of a casing in an earthen bore, improving drill bit service life and improving bonding between a cement liner installed around a casing in an earthen bore.
- It is conventional practice to couple a drill bit to a tubular, for example, a drill string, and to rotate the drill bit against an end of an earthen bore to extend the bore into the earth's crust. A drill string may comprise slick (i.e., constant diameter) drill collars or enlarged (relative to the mid-section of the joints) drill collars. In casing while drilling applications, the drill bit is coupled to a casing. Drill cuttings are removed from the bore by circulating drilling fluid through a fluid passage in the drill string (which, in drilling applications, may be a drill string or a casing) to the drill bit, and back to the surface through an annulus between the drill string and the earthen bore. As the drill bit penetrates the earth's crust, the drill string advances through the bore at a rate of penetration of the drill bit. In conventional drilling operations, the drill string may rotate along with the drill bit. In some drilling operations, such as casing while drilling, the drill bit may rotate independently of the drill string using a bottom hole assembly (BHA) that includes a mud motor powered by pressurized drilling fluid to rotate the drill bit. The weight or load imparted to the drill bit by the drill string is a factor that determines the rate of penetration.
- In drilling operations, it is advantageous to stabilize the rate of advance of the drill string through the borehole to prevent unwanted spikes in the load imparted to the drill bit. Intermittent or sporadic advances of the drill string within the bore may cause drill bit damage due to excessive loading. This problem may be greater in bores having a highly deviated section due to substantially greater frictional resistance between the bore and the drill string. In highly deviated sections of a bore, the weight of the drill string (and contents) bear on the floor, or downwardly disposed side, of the bore to cause substantially greater frictional resistance to advance of the drill string through the bore. The result may be intermittent and erratic advances of the drill string and related peak loads imparted to the drill bit.
- An attempt to stabilize the rate of advance of a drill string through a bore having a highly deviated section uses an oscillating valve disposed within a BHA coupled to the drill string. Pressurized drilling fluid may be pumped through the fluid passage in the drill string to drive the oscillating valve to vibrate the BHA and reduce frictional resistance to advance of the drill string through the bore.
- An oscillating valve powered by pressurized drilling fluid may consume a substantial portion of the mechanical energy provided to the BHA, leaving less mechanical energy to drive the mud motor and/or to circulate and remove drill cuttings.
- After an earthen bore is drilled to a targeted depth, it is conventional practice to cement a casing in the bore to prevent collapse and stabilize the bore. A float device, such as a float shoe or a float collar, may be coupled to the casing, and the casing may be run into the bore and positioned within a targeted interval. The casing may also be radially positioned (or “centered”) within the bore using casing centralizers, such as bow spring centralizers, coupled at intervals along the casing to provide an annulus between the casing and the bore. Cement slurry is pumped through the casing with cementing plugs to facilitate displacement of the slurry through the float device and into the annulus. The cement slurry solidifies to provide a protective cement liner around the casing. Alternately, an inner cementing string may be run through the casing and stung into a mandrel, for example, a mandrel in a float device, and cement slurry may be delivered through the inner cementing string and the float device to the annulus.
- The quality of the cement liner may be improved by conditioning the cement slurry within the annulus while and/or or after the cement slurry is displaced into the annulus. The cement slurry may be conditioned by agitation to induce turbulent fluid flow, disrupt fluid channeling and promote bonding of the cement liner to the bore.
- Reciprocation and/or rotation of the casing using the drilling rig are conventional methods of agitating a cement slurry. In substantially vertical bores, where casing hangs primarily in tension, casing is more easily reciprocated and/or rotated within the bore. In bores having highly deviated sections, reciprocating or rotating the casing may be difficult because the weight of the casing (and contents) bears heavily on the floor, or downwardly disposed side, of the bore. As a result, casing rotation and/or reciprocation within a highly deviated section of a bore causes unwanted wear and stress on the casing, on the casing centralizers and on rig equipment used to move the casing within the bore.
- What is needed is a method to stabilize the advance of a tubular, such as a drill string, through an earthen bore to prevent excessive drill bit loading. What is needed is a method to condition a cement slurry displaced into an annulus between a tubular, such as a casing, and a bore. What is needed is a method to condition an annular flow or volume of cement slurry around a casing without imparting unwanted stress and wear on the casing, casing centralizers and rig equipment.
- One embodiment of the invention is a method of stabilizing drill bit loading to extend the usable life of a drill bit comprising the steps of coupling a drill bit to a drill string (which may be a casing used in a casing while drilling application), coupling a vibration generator to the drill string, coupling a power source, such as a battery, to the vibration generator, running the drill string into a bore to engage the drill bit with an end of the bore, rotating the drill bit to extend the bore, and activating the vibration generator to vibrate a portion of the drill string within a highly deviated section of the bore to reduce frictional resistance to advance of the drill string and thereby stabilize drill bit loading.
- Another embodiment of the invention is a method of reducing frictional resistance to advance of a tubular through a highly deviated section of a drilled earthen bore comprising the steps of coupling a vibration generator to the tubular, e.g., a casing, coupling a power source, such as a battery, to the vibration generator, running the tubular into a bore, and activating the vibration generator to vibrate a portion of the tubular within a highly deviated section of the bore to reduce frictional resistance to advance of the casing and thereby stabilize advance of the casing through the bore towards the targeted interval.
- Another embodiment of the invention is a method of conditioning a cement slurry to promote improved bonding between a cement liner and a bore comprises the steps of coupling a float device (such as a float shoe or a float collar) to a casing, coupling a vibration generator to the casing, coupling a power source (such as a battery) to the vibration generator, running the casing into a bore, displacing a volume of cement slurry through the casing and the float device and into an annulus between the casing and the bore, and activating the vibration generator to vibrate a portion of the casing to condition a portion of the volume of cement slurry adjacent the vibration generator.
- In the methods described above, the vibration generator may be activatable using a pressure sensor disposed in communication with the power source to detect an activating condition. For example, in one embodiment, a pressure sensor may be disposed to detect the pressure in a fluid passage in the drill string, the casing, in a sub or in the float device. The pressure sensor may be coupled to a microprocessor programmed to monitor readings of the pressure sensor and to recognize an activating condition or sequence. For example, but not in the way of limitation, the pressure sensor may detect a first predetermined pressure threshold, followed by a pressure trough lasting for a predetermined interval of time, followed by a second predetermined pressure threshold, altogether comprising a sequence of events recognizable by the microprocessor. In response, the microprocessor may close an electrical circuit to provide current from the a power source to a motor to activate the vibration generator. A subsequent predetermined event or sequence may be used to deactivate the vibration generator.
- One embodiment of the method of conditioning a cement slurry may comprise coupling the vibration generator to a float device, such as a float shoe or float collar. Another embodiment of the method of conditioning a cement slurry may comprise coupling the vibration generator to one or more drillable components, such as a float device, so that the vibration generator and the float device may be drilled or destroyed to provide an unrestricted passage through the casing to facilitate further extension of the bore after the cementing step.
- An embodiment of an apparatus that may be used to implement a method described above comprises a mass rotatably coupled within a frame and having a mass center, a motor coupled to the mass, and a power source coupled to the motor to provide energy for spinning the mass on an axis offset from the mass center to produce reactive vibrations in the frame.
- A power source for providing energy to a motor may, in one embodiment, comprise a battery having a high power-density including, but not limited to, a nickel-cadmium battery, a nickel-metal-hydride battery or a lithium-ion battery. While high power-density batteries may provide for optimal performance of the vibration generator, a conventional lead acid battery may also be used.
- A mass to be spun to produce vibrations may, in one embodiment, comprise an elongate member of a high density material, such as lead, or it may comprise a substrate to which weighted attachments are secured to provide a mass center offset from an axis about which the mass is spun. It will be understood that factors affecting the frequency and magnitude of vibrations includes the weight of the mass, the offset between the axis of rotation and the mass center, the angular velocity of spinning of the mass and the relative size of the sub, float device or other frame to which the mass is secured.
- The foregoing, as well as other, objects, features, and advantages of the invention will be more fully appreciated and understood by reference to the drawings, described below, and to the claims appended hereto.

It will be understood that theball 57 is disposed by thespring 58 against therestriction 59 to prevent flow through therestriction 59 until the pressure in thefluid passage inlet 61 exceeds the pressure in thefluid passage outlet 63 by a differential that is sufficient to overcome the force of thespring 58 against theball 57, at which time fluid (not shown) will flow from thefluid passage inlet 61, past theball 57, through thefluid passage outlet 63 and through theexit port 74. Operating in this manner, thefloat device 62 prevents fluid within the bore 2 (seeFIG. 3 ) from flowing into thefluid passage inlet 61 and entering the casing 30 (seeFIG. 3 ). - The terms “comprising,” “including,” and “having,” as used in the claims and specification herein, shall be considered as indicating an open group that may include other elements not specified. The terms “a,” “an,” and the singular forms of words shall be taken to include the plural form of the same words, such that the terms mean that one or more of something is provided. The term “one” or “single” may be used to indicate that one and only one of something is intended. Similarly, other specific integer values, such as “two,” may be used when a specific number of things is intended. The terms “preferably,” “preferred,” “prefer,” “optionally,” “may,” and similar terms are used to indicate that an item, condition or step being referred to is an optional (not required) feature of the invention.
