| 摘 要： | 川西坳陷低渗致密气藏部分压裂井由于地质条件、压裂工艺设计、压裂液体系与支撑剂的选型、施工质量等原因导致压裂达不到增产目的或者压后产量递减快。通过对川西低渗气藏压裂低效原因进行分析,阐述了影响重复压裂效果的关键技术,对川西低渗致密气藏重复压裂改造具有一定的指导作用。

| Abstract: | Due to geological conditions, fracturing design, fracturing-fluid system, proppant selection and fracturing quality, some fractured wells in low-permeability tight gas reservoir of western Sichuan depression lead to problems in which fracturing fails to live up to the purpose of stimulation and production decreases rapidly after fracturing. Some causes are analyzed and the key technologies that influence refracturing effect are discussed. It will provide some guidance to refracturing treatment in the low-pe... |
