【摘要】：塔里木盆地山前井是塔里木油田油气勘探开发的重要区域之一。针对山前井地层研磨性强、可钻性级值高,单只钻头进尺低,钻头消耗量大,机械钻速低,钻井成本高等问题,引进涡轮配合孕镶金刚石钻头钻井技术。2口山前井钻进实验数据表明:博孜102井配套工具进尺704 m,纯钻时间407.5 h,平均机械钻速1.73 m/h;克深2-1-14井配套工具进尺146.8 m,纯钻71.75 h,平均机械钻速2.05 m/h。两组配套工具与邻井同层PDC钻头、牙轮钻头对比,钻井速度提高了2~4倍,单只钻头平均进尺提高了3~10倍,平均纯钻时间提高了1.7~2.5倍。工具实验结果表明,涡轮配合孕镶金刚钻头钻井技术在塔里木山前井具有较好的提速效果,可为塔里木山前井钻井提速提供技术支持。
[Abstract]:Piedmont well in Tarim Basin is one of the most important areas for oil and gas exploration and development in Tarim Oilfield. Aiming at the high ground grinding ability, high drillability grade, low drill bit advance, large bit consumption and low mechanical drilling speed, the paper points out that the well in front of Tarim Basin is very important for oil and gas exploration and development in Tarim Oilfield. In order to solve the problem of high drilling cost, the drilling experiment data of .2 Piedmont wells with turbo matching diamond bit drilling technology show that the matching tool of Bozi 102 well is 704 m. The drilling time was 407.5 h and the average drilling speed was 1.73 m / h; Kesheng 2-1-14 matching tool is 146.8 m, pure drilling is 71.75 h, average mechanical drilling speed is 2.05 m / h. The two sets of matching tools have the same layer PDC bit as adjacent wells. Compared with the cone bit, the drilling speed is increased by 2 ~ 4 times, the average advance of a single bit is increased by 3 ~ 10 times, and the average drilling time is increased by 1. 7 ~ 2. 5 times. The turbine combined with impregnated diamond bit drilling technology has a better speed increasing effect in the front well of Tarim Mountain, which can provide technical support for the drilling speed increase in the front well of Tarim Mountain.
