| Abstract: | Yuanba 121H well marine gas reservoir is buried deep,the depth of horizontal wells is above 7000m,the temperature in bottom is high,and the pressure is high,which have very high requirements on horizontal drilling.In order to efficiently develop marine reservoir in Yuanba and complete "Twelve-Five" planning strategic objectives,Sinopec conducted pilot research on Yuanba 121H well.This article focused on analysis of the difficulty in oblique section and horizontal section of Yuanba 121H well,explored to use high temperature resistance screw drilling tool and high temperature resistance MWD control trajectory,and summed up a set of trajectory control technology of exceeding horizontal well in Yuanba district. |
