摘要:

结合镇泾油田钻井现状，系统介绍了主要钻井工程工艺技术措施，重点分析“优快钻井”面临的钻井井漏、井眼稳定、定向钻井工艺技术优化、钾胺基聚合物钻井液体系抗盐侵的维护处理、“压稳防漏固井”等技术难点，结合钻井实践提出“优快钻井”的技术措施与方案，对该地区钻井施工具有一定的参考意义。

Abstract:

Based on the present drilling situation of Zhenjing oilfield, the paper systematically introduced the main technology measures of drilling engineering, analyzed the technical difficulties of high quality and high speed drilling: drilling well leakage, borehole stability, optimization of directional drilling technology, maintenance of resistance to salt erosion by potassium amine group polymer drilling fluid and leakproof by steady pressure well cementing. According to the drilling practice, the high quality and high speed drilling was put forward, which could be the reference to the drilling construction in Zhenjing oilfield.
