辽东湾SZ36—1油田高难度丛式钻井

Extremely Difficult Cluster Drilling in SZ 36—1 Oil Field in Liaodong Bay

本文介绍渤海辽东湾SZ36-1 油田实验区AⅡ平台丛式钻井的情况。该平台造斜点浅,水平位移大,井斜角大,且地层疏松不胶结,裸眼段长,中靶精度要求高。用275天累计进尺32572m钻完了16口定向斜井,中靶率100％。

The Situation about cluster drilliog on A Ⅱ platform at the experimental area in SZ 36--1 oil field in Liaodong Bay is presented in this article. The well has a shallow deviating point, a large hori- zontal departure,a big deviation angle and a long open hole,the formation is loose and unconsolidated, and the precision reaching the target. is highly prescribed. Sixteen directional deviated wells were drilled in 275 days, obtaining 32572 m. of accumulated footage and 100% of the rate of reaching the target.
