水平井完井方式与分段压裂工艺适应性研究

Adaptability of Horizontal Well Completion and Staged Fracturing Technology

优选水平井的完井方式,需要考虑储层类型、驱动方式、产层岩性、钻井工艺、生产控制等;如果需要进行水平井压裂作业,就不得不考虑到水平井完井方式与分段压裂工艺是否适合。论述了水平井完井方式分别与水力喷射分段压裂工艺、限流压裂工艺、机械分段压裂等工艺的适应性研究结果,可为水平井在选择完井方式及其分段压裂工艺上提供借鉴。

During choosing the horizontal well completion method, we need to consider reservoir type, drive way, producing formation lithology, drilling technology, production control; if the horizontal well fracturing operation is required, it is necessary to take into account the adaptability of the horizontal well completion method and the section fracturing technology. In this paper, research results about the adaptability of horizontal well completion method with hydraulic injection section fracturing technology, limited flow fracturing process, mechanical fracturing and other technology were introduced, which could provide reference for selection of completion methods and section fracturing technologies.
