Study and application of drilling technology for Permian igneous rocks in Shunbei Oil and Gas Field
摘要
Abstract
The Permian igneous rocks formation in Shunbei Block of Tarim Basin has the characteristics of large thickness,high hardness,developed fractures and strong heterogeneity,which leads to low ROP and long plugging time.the average drilling cycle increases by 1.5 times compared with the adjacent areas.In recent years,through continuous strengthening the drilling fluid plugging technology and the optimization of high-efficiency drilling technology,the leakage and plugging time have been gradually shortened,and the drilling index has been increased year by year.In this paper,the main controlling factors affecting the long plugging time and low penetration rate are analyzed,and the plugging technology is improved by adding bamboo fiber and deformed particles into the plugging slurry.The applicable conditions of the impact tool are clarified,and the PDC bit with aggressiveness and impact resistance is optimized.Technical countermeasures such as improving the structure of the mixed bit and supporting the high torque and long life screw have achieved remarkable results in increasing drilling speed and reducing cost,which provides guidance for accelerating the efficient exploration and development of Shunbei Oil and Gas Field.关键词
