水平井裸眼完井分段压裂技术研究

摘要

水平井裸眼分段压裂作为低压、低渗透油气藏开发的重要增产措施之一,日益受到广泛关注.介绍了水平井裸眼分段压裂工艺实施过程,给出了1种比较合理的水平井裸眼分段压裂管柱结构；针对该工具分析了压裂设计的难点.现场应用表明,应用该项技术进行水平井裸眼压裂可获得较高产能,经济效益显著.%The staged fracturing for openhole is an important measure to increase production of the low pressure and permeability reservoir, which is greatly concerned. The construction process of multistage fracturing of horizontal bare hole wells was described, a more reasonable multistage fracturing string of horizontal bare hole wells was presented,and the fracturing design difficulties was analyzed. Field application results showed that with the technology of multistage fracturing of horizontal bare hole wells,higher productivity was obtained and economic results were obvious.
