复合钻进技术在吐哈油田的应用

Applications of Complex Drilling Techniques in Tuha Oilfield

吐哈油田丘陵西块由于地层倾角大 ,地层走向一致 ,导致方位稳定不变 ,井斜控制极为困难 ,普遍采用降钻压吊打防斜 ,钻井速度很慢。在保证井身质量的前提下 ,为加快钻井速度 ,在丘陵西块运用了复合钻井技术 ,取得了明显效果。并将该技术推广应用到其它区块及定向井施工中 ,极大地简化了施工工序 ,降低了劳动强度 。

In order to improve drilling penetration rate as well as ensuring borehole quality, complex drilling techniques are applied in western block of Qiuling in Tuha Oilfield and obvious effects were obtained in this area. The technique has been widely used in other blocks and in directional drilling operations. It can greatly simplify operating procedures and improve drilling efficiency.
