| 摘 要： | 目前苏里格气田水力加砂压裂在压裂液优化、支撑剂选择、泵注程序参数确定和液体返排技术方面存在较多问题.针对这些问题进行了认真研究,优选出了适合该区块的压裂液配方和支撑剂,优化了压裂液配置程序,提出了"适度规模、小排量、造长缝、合理砂浓度、有限导流能力"的水力压裂改造思路.经现场试验,桃7-8-5和桃7-9-14井均获得大幅增产,效果显著.

| Abstract: | In Sulige gasfield, there are many technical problems existing in hydraulic sand fracturing, such as fracturing-fluid optimization, proppant selection, program-parameter determination and liquid flowback. In this paper, one problem which emphasizes the poor effect of sand fracturing on the gasfield is fully studied; the fracturing-fluid formula, proppant, and optimized fluid configuration program, which are suitable to the block, have been optimized; and the thoughts on hydraulic fracturing, including moder... |
