煤层气井用压裂液技术研究

The technology of fracturing fluid in CBM well

摘要: 针对沁水3^#煤储层的地质特征,在优选水基压裂液添加剂的基础上,结合压裂工艺的要求,形成了不同类型水基压裂液配方体系,并且较完整地对煤层气井用水基压裂液配方体系进行了测试。通过对优选的不同水基压裂液性能的实验表明,其各项性能较好地满足了煤储层和压裂工艺的要求。

Abstract: A water type based fracturing fluid formulation system is established,based on geological characteristics of Qinshui 3^# coal seam reservoir,water based fracturing fluid additive and fracturing requirement.The test for system in coalbed well is described in this paper.The test result indicates that the water type based fracturing fluid formulation system can meet the requirements of coal reservoir and fracturing technology.
