Abstract
A polish rod sealer comprises a polish rod, a high temperature and high pressure resistant expansion pipe, a high-temperature high-pressure emergency sealing device and a seamless polish rod clamp. The high temperature and high pressure resistant expansion pipe, the high-temperature high-pressure emergency sealing device and the seamless polish rod clamp are sleeved on the polish rod, the upper end of the high temperature and high pressure resistant expansion pipe is fixedly connected with the polish rod in a tight holding manner while the lower end of the same is connected with the high-temperature high-pressure emergency sealing device in a threaded manner, the high-temperature high-pressure emergency sealing device is seamlessly connected with the seamless polish rod clamp, and the lower end of the seamless polish rod clamp is connected with a wellhead via a slip of the seamless polish rod clamp. The polish rod sealer has the advantages that sealing is more reliable as compared with tightening type sliding seal; high-temperature high-pressure emergency sealing can substitute for expansion sealing temporally, the expansion pipe is convenient to replace, and the wellhead can be closed when the polish rod is broken so as to prevent blowout; oil well management is facilitated, the seamless polish rod clamp substitutes for a toothed square clamp, and oil well management measures such as oil well pump bumping, anti-impact stoke adjustment and stroke adjustment are faster and more convenient to implement; efficiency of an oil pumping unit system is improved, and wear and frication of up-down strokes of an oil pumping rod are reduced.
Description
Technical field
The present invention relates to the oil extraction oil pumper, particularly relate to pumping unit rod sealing device.
Background technology
The fastening-type slipper seal devices of the most of employings of the oil-extractor polish-rod of heavy oil wells at present, has complex structure, complex operation, need the frequent packing of changing, the stop pumping time is long, rate while both affecting oil well production, increased again labor strength and cost of production, also the weak point such as easy bleed contaminated environment.
Summary of the invention
The technical problem to be solved in the present invention is, provide a kind of sealingly secure reliable, reduce and safeguard the sealer workload, improve oil pumper production efficiency, reduce the Novel wellhead polished rod sealer of maintenance cost.
The technical scheme adopted is:
Polished rod sealer, comprise polished rod, high temperature high voltage resistant telescoping tube, the emergent sealing device of HTHP, seamless polish rod clamp.Described high temperature high voltage resistant telescoping tube, the emergent sealing device of HTHP, seamless polish rod clamp are sleeved on polished rod, high pressure resistant high temperature telescoping tube upper end adopts anchor ear fixing seal mode closely to be fixedly connected with polished rod, the high pressure resistant high temperature telescoping tube lower end emergent sealing device of HTHP that is threaded, the emergent sealing of the HTHP seamless polish rod clamp of seamless link (one), seamless polish rod clamp lower end connects production wellhead with its slips.
Above-mentioned high temperature high voltage resistant telescoping tube, heatproof≤200 ℃, withstand voltage>=2.5MPa, stretching frequency≤6min
-1, under environment temperature-35 ~ 45 ℃, wind speed≤8 grade operating mode, after compression, length is 0.5 ~ 1.0 meter, at least 3 meters of spread lengths.
The above-mentioned HTHP sealing device of meeting an urgent need, heatproof≤370 ℃, withstand voltage≤14.0Mpa.
Advantage of the present invention is:
1, adopt fixing seal, seal solid and reliable, more reliable with respect to the fastening-type slipper seal;
2, sealingly secure is reliable, and the emergent sealing of HTHP can temporarily substitute flexible sealing, is convenient to change the high temperature high voltage resistant telescoping tube, can seal well head during light rod-broken, prevents blowout;
3, facilitate oil well management, seamless polish rod clamp substitutes tooth side's clamp, implement oil well touch pump, adjust dead space, more convenient while adjusting the oil well management measure such as stroke;
4, improve Analysis of Oil Well System Efficiency, reduce the resistance of sucker rod up-down stroke mill, improve the power of motor utilization rate.
The accompanying drawing explanation
Fig. 1 is structural representation of the present invention.

The specific embodiment
Polished rod sealer, comprise polished rod 4, high temperature high voltage resistant telescoping tube 1, the emergent sealing device 2 of HTHP, seamless polish rod clamp 3.Described high temperature high voltage resistant telescoping tube 1, the emergent sealing device 2 of HTHP, seamless polish rod clamp 3 are sleeved on polished rod 4, high pressure resistant high temperature telescoping tube 1 upper end is held the fixing seal mode tightly with polished rod 4 employings and closely is fixedly connected with, the high pressure resistant high temperature telescoping tube 1 lower end emergent sealing device 2 of HTHP that is threaded, the HTHP seamless polish rod clamp 3 of sealing device 2 lower end seamless link of meeting an urgent need, seamless polish rod clamp 3 lower ends connect production wellhead with its slips.Described high temperature high voltage resistant telescoping tube 1, heatproof reach 200 ℃, the withstand voltage 2.5MPa that reaches, and stretching frequency reaches 6min
-1, under environment temperature-35 ~ 45 ℃, wind speed≤8 grade operating mode, after compression, length is 0.7 meter, 3.2 meters of spread lengths; The HTHP sealing device 2 of meeting an urgent need, heatproof reaches 370 ℃, the withstand voltage 14.0Mpa that reaches.
Operating principle
A is in the oil pumper course of work, polished rod passes the emergent sealing device 2 of HTHP telescoping tube 1, HTHP, seamless polish rod clamp 3, well head four-way and enters in pit shaft and move up and down, polished rod 4 moves up and down in process, high temperature high voltage resistant telescoping tube 1 is because upper end is fixed on polished rod 4, therefore its upper end moves up and down with polished rod, high temperature high voltage resistant telescoping tube 1 lower end, the emergent sealing device 2 of HTHP, seamless polish rod clamp 3 are fixedly connected on well head, and these parts do not move.In upstroke, 1 elongation of HTHP telescoping tube, minute quantity liquid upwards flows into high temperature high voltage resistant telescoping tube 1 inner chamber by the gap that polished rod and well head, seamless polish rod clamp 3, HTHP are met an urgent need between sealing device 2 with polished rod; In down stroke, HTHP telescoping tube 1 shrinks, in high temperature high voltage resistant telescoping tube 1 inner chamber, liquid is extruded with polished rod and by the gap that polished rod and well head, seamless polish rod clamp 3, HTHP are met an urgent need between sealing device 2, flows in pit shaft downwards, guarantee that polished rod is in the process of moving up and down, in pit shaft, liquid can not flow out this polished rod sealer.
B is in the oil pumper course of work, and when light rod-broken occurring fall in pit shaft, the effect of HTHP telescoping tube 1 sealing wellhead was lost efficacy, and enables the emergent sealing device 2 of HTHP and in envelope mode entirely, seals well head and prevent that blowout from occurring.
C is according to the oil well production situation, needs to implement to touch pump, adjusts dead space, while adjusting the oil well management measure such as stroke, and seamless polish rod clamp 3 blocks polished rod to intermediate closed, is convenient to oil pumping machine unloading.
