Description
Technical field
The utility model relates to oil drilling machine field, more specifically to a kind of can the oil drilling of positioning operation.
Background technology
At present, petroleum industry is in drillng operation, and for ensureing the construction precision of completion all kinds of underground work of oil well later, general adopted method the casing string within the scope of certain depth installs a casing nipple, as the reference mark of the down-hole degree of depth.Although the method accurately can provide the foundation of down-hole depth calculation, function singleness can only be determined the degree of depth and can not determine orientation, and with instrument be difficult to the use of.
Underground location is the key problem in technology of multilateral well, and positioner needs enough axial load resistants, Chinese People's Anti-Japanese Military and Political College's moment of torsion and high pressure sealing ability.Domestic and international specialty limits due to technology, adopts slip-type anchor tool to add in old street district Multilateral Wells
Packer or simply with sleeve pipe long distance tieback location from bottom to top, these instruments cause many disadvantages due to the inherent shortcoming of itself, and after completion, main run through casing size significantly reduces, and brings a lot of problem to follow-up oil recovery, well workover and oil formation improvement etc.External specialized company is after completing multilateral well, and just must can carry out subsequent job with the special instrument of the said firm, construction cost is large.Locating unreliable is another shortcoming of above-mentioned instrument, poor-performing in axial load resistant, Chinese People's Anti-Japanese Military and Political College's moment of torsion and high pressure sealing ability, slips has hard defects to damage to sleeve pipe, long distance sleeve tieback cannot bear larger load and moment of torsion, cause directed inaccurate, under prop up well tool not easily centering position and orientation, Zhi Jing " selective reentry " is become and beats a large difficult point of multiple-limb technology.Moreover the use of above-mentioned instrument, after completion, main run through casing size significantly reduces, and therefore, should not make a call to the Multilateral Wells of more than 3 in the main sleeve pipe of small size in a main sleeve pipe.But the domestic production sleeve pipe overwhelming majority is small size sleeve pipe, cause the domestic difficulty that digs a branch well higher, success rate is less, limits application and the popularization of domestic multi-lateral well technology.
