| 摘 要： | 对于非均质严重、地层能量不足的“三低”油层,复合压裂技术将高能气体压裂和水力压裂两种技术优势互补,有效地达到增产增注的目的。通过对几种压裂手段的效果对比和8口实验井的现场统计表明,复合压裂工艺在长庆油田安塞油区和陇东油区施工成功率100%,有效增产率100%,效果明显好于单一的水力压裂或高能气体压裂工艺。该工艺有利于长庆油田“三低”油藏挖潜改造。

| Abstract: | To the three low oil layers with seriously low heterogeneity and inadequate formation energy,compound fracture technology combines advantages of high energy gas fracturing technology with hydraulic fracturing technology to effectively achieve the goal of increasing productivity and injection increasing.Contrasting effect of some kinds of fracturing technology and field statistics to eight experimental wells show that successful rate is 100% by using compound fracture technology in Ansai and Longdong blocks ... |
