Description
Technical field
The invention belongs to oil and gas development field, be specifically related to a kind of self-righting formula down-hole draw-gear.
Background technology
Since the nineties in 20th century, horizontal well, extended reach well, Drilling Technology for Multi-Bore Well have obtained swift and violent development, are playing the part of more and more important role in petroleum exploration and development process.But along with borehole condition becomes increasingly complex, the growth of the increase of hole angle, horizontal section length, being lowered to of downhole instrument becomes more and more difficult, be difficult to by under self gravitation to shaft bottom.Downhole instrument is conveniently lowered to and takes out the important leverage that becomes horizontal well development.Traditional downhole instrument is lowered to mode to be had following several: Drill Pipe Technology, pump into quickly pole technology of rigidity, and continuous-tube conveying etc., these methods engineering amounts are large, length consuming time, ground installation complexity.And a frequent lower tubular column is very serious to the wearing and tearing of sleeve pipe, may damage accurate instrument and cable.Research and develop simple to operately, conveniently down-hole running tool is more and more received people's attention.
Meanwhile, horizontal well cable puller progressively moves towards practice from design, and progressively grows up.Wheeled tractor relies on the stiction of driving wheel and the borehole wall to overcome the resistance that cable slides, thereby instrument is pushed to horizontal object section.This horizontal well cable puller can meet the requirement of the multiple underground work such as well logging, well workover, perforation, and is widely used.
Horizontal well downhole tractor is scale down-hole crawl device, traction robot etc. again, is the downhole tool that a kind of energy down-hole provides tractive force; Can be divided into three kinds of roller creeping-type, crawler belt creeping-type and telescopic slide formulas by its motion principle, wherein wheeled appearance the earliest.And draw-gear is downhole tractor obtains tractive force direct driving force source in shaft bottom, be also the most critical of tractor, the part of core.Having many companies in succession to develop abroad can be at the horizontal well draw-gear of down-hole independently working (that is: cable puller).Mainstream product mainly comprises: the horizontal well cable puller of a kind of practicality of Statoil, Maritime Well Service (MWS) and the development of Welltec company of Denmark, a kind of telescopic tractor of SmarTract company of Britain design, the wheeled cable puller in down-hole of Sondex company of Britain exploitation etc.
