Description

Horizontal well rod tube conveying dynamic logging technique rod tube post

Technical field

The present invention relates to horizontal well rod tube conveying dynamic logging technique rod tube post, belong to oilfield horizontal well well logging field.

Background technology

Production Logging in Horizontal Wells generally adopts three kinds of modes such as the conveying of oil pipe coiled tubing, tractor conveying, Hydraulic transportation both at home and abroad at present.Existing oil pipe conveying and Hydraulic transportation, pumping liquid, liquid enters stratum, directly affects test result, and tractor conveying and coiled tubing carry input cost higher.In the urgent need to finding a kind of testing method as straight well is logged well.

Chinese patent literature " continuous tube horizontal borehole process and device " publication number: CN101382069A, publication date: on March 11st, 2009, adopt continuous-tube as the means of delivery of downhole logging instrument, but horizontal well is adopted for numerous machine, also cannot carry out producing profile testing under normal production status at present.

Chinese patent literature " horizontal well gas lift method producing profile testing process adopted by machine " publication number: CN101403292A, publication date: on April 8th, 2009, adopt the gaslift mode of production, tester is driven, " mainly solving the problem that existing horizontal well cannot carry out producing profile testing under normal production status " with tractor.Shortcomings is that the gaslift mode of production not only needs special nitrogen to produce car and compression locomotive, and truly can not reflect that the normal production status of horizontal well adopted by machine.

Chinese patent literature " preset production fluid section plane test method of mechanical mining horizontal well and special shaft mouth test apparatus " publication number: CN101403291A, publication date: on April 8th, 2009, " method adopting prior preset tester and downhole tractor to combine coordinates special shaft mouth test apparatus to realize machine and adopts horizontal well presetting system producing profile testing." Shortcomings is that whole technique is more complicated.

Chinese patent literature " method for testing horizontal well oil conduit transportation under pumping state " publication number: CN101377127A, publication date: on March 4th, 2009, adopts conventional pumping tool wire rope swab to carry out pumping production, oil pipe conveying test.Shortcomings is because test cable is positioned at outside oil pipe, and not only whole to remove technique more complicated, and whether goes out the uncertainty of protective due to the leakage of pumping instrument and tester, can not reflect that the normal production status of horizontal well adopted by machine.
