| 摘 要： | 巴喀下侏罗统气藏具有埋藏深、高温、高压和岩性致密的地质特点,单井自然产能极低,绝大多数气井都需经过压裂改造才能获得工业产量。该文根据气藏特征,分析了压裂改造技术的难点,探索出了高温降阻延迟交联压裂液体系与大排量、大规模、中高前置液、中高砂比、组合粒径加砂的压裂工艺技术,该技术体系应用于巴喀区块致密气藏取得了显著的增产效果和较好的经济效益。

| Abstract: | The J_1b reservoir in block Baka is characterized by deep buried depth,high temperature,high pressure and compact lithology,which leads to very low natural production of single well,and most of the gas wells can obtain high production by fracturing stimulation.According to the characteristics of gas reservoir,the main difficulties of fracturing stimulation technology are analyzed,and the delayed crosslinked fracturing fluid system with high temperature and resistance reduction and the fracturing technique o... |
