Research On Well Trajectory Control In The Inclined Of Block On Daqing The Sixth Oil Production Plant

In La-bei west block of Sixth Oil Production Plant of Daqing drilling area.some factors such as the large stratigraphic dip, more hard interlayer and strong formation natural deflectingability result in a series of problems including in the process of drilling construction the mechanical drilling rate of lower well section is low, borehole curvature is large, immersion timeof oil layer is long and well drilling cycle is delayed, especially the target precision of directional well is low. To solve these problems,\through studying the formation rock characteristicsand formation natural deflecting law of this area and some related factors, the corresponding technical countermeasures are developed. And thetopic about the study of optimized drilling technology for apt skew blocks of Sixth Oil Production Plant is put forward, in order to achievethe goals、of enhancing the mechanical drilling rate and ensuring the quality of well bore.This article emphatically from the Sixth Oil Production Plant of easily inclined areaformation natural deflecting law, BHA and drilling parameters optimization, theSixth Oil Production Plant of inclined area ground moving location method, directional wellborehole trajectory control technology from four aspects, It proposed theSixth Oil Production Plant of daqing oil field is inclined block hole control technology. Thetechnology through field test, and ultimately reached the oil extraction factory of easilyinclined block against the purpose of the inclined to play fast.
