梁9-平1井位于梁家楼油田中区西部,东临纯56块,目的层为沙三中油层。该井为二靶点水平井,钻探目的是开发梁9断块西部沙二中构造高部位剩余油,该井设计井深3076.43 m,实钻水平段长337.37 m,完钻层位S3段,完钻原则是B靶中靶后留足35 m口袋完钻。由于井身结构设计合理,井眼轨迹控制方法得当,且采用了MWD+电阻率测试仪的轨迹跟踪测量技术,加之技术保证措施正确,各方面配合密切,从造斜点开始一趟钻钻达A点,仅用26 d完钻,取得了较好的经济效益和社会效盖。

Liang9-ping1 well is located in west of Liangjialou Oilfield middle area,it’s east near Chun56 block,production formation is S3.This well configuration of is two target point horizontal well. Residual oil in Liang9 block exploitation is the main purpose of drilling.the well design dep this 3076.43 m,horizontal interval is 337.37 m,measured layer is S3.Due to ho le trajectory design accurate,well path control method suitable and using MWD+ resistivity logging instrument,This well was successfully drilled from build up point to A target, the net drilling time is only 26 d,and has better economic benefit and social benefit.
