油田完井方式工艺技术研究

Study on Well Completion Mode and Technology in Oilfield

分析了海上油田钻完井过程常见的完井工艺技术,特别是针对油田地层容易出砂的情况下,采用多种完井方式,以实现有效防砂、层间封隔以及分层注水。采用优质筛管、裸眼/管内砾石充填、套管射孔、压裂充填、高速水充填的综合完井防砂方式,能达到较好的防砂效果。

This paper analyzes the common well completion technologies in the process of drilling and completion in offshore oil fields,especially in the case of easy sand production in oil fields,a variety of well completion methods are adopted to realize effective sand control,interlayer sealing and layered water injection.The comprehensive completion sand control method of high-quality screen pipe,open hole/in pipe gravel packing,casing perforation,fracturing packing and high-speed water packing can achieve good sand control effect.
