摘　　要：吐哈盆地巴喀区块位于北部山前带,地层倾角大、可钻性差、岩性多变,由于其特殊的地质油藏特征导致该区块机械钻速低、钻井周期长、井身质量难以保证,如何实现该区块防斜打快是吐哈急需解决的难题。本文介绍了巴喀区块防斜打快取得的新进展,通过对该区钻井难点及制约因素的分析,开展了个性化钻头优选、充氮气欠平衡钻井、MWD+低速螺杆复合钻井、PowerV垂直钻井等新工艺、新技术的试验与应用。实践表明,上述技术能够实现巴喀气田防斜打快的预期目标,是加快该区块勘探开发进程的重要技术,具有推广应用价值。The Baka block of tuha basin is located in northern piedmont belt,with big diplog,poor drillability,and changeable lithology.Due to its special geological reservoir characteristic,the penetration rate of this block is low,the mechanical drilling cycle takes long time and body quality is poor.How to solve the problem is urgent for toha oilfield.This paper introduces the new progress of preventing from inclining in the baka block.Tne practice shows the bit type,underbalanced drilling,and MWD composite guidance technology application can realize baka anticipated target,which accelerates baka block exploration and has practical value.
