| 摘 要： | 论述了陕甘宁盆地东部地区上古生界低渗透砂岩气藏的主要损害因素。室内研究表明,采用粘土稳定剂,可将水敏和微粒迁移的综合损害由95％左右降至40％左右,采用表面活性物质,有利于滤液反排,使水锁损害明显降低,控制围压突然上升可缓和压力敏感效应对损害的加剧作用,并在此基础上研制出了低损害完井液配方。

| Abstract: | The main damage factors of the upper Palaeozoic gas reservoir are discussed in detail Tests shown that damage due to water sensitivity and fine migration can be reduced by use of clay stabilizer , damage due to water lock can be reduced by use of surfactant . Six compositions of drilling and completion fluids are given against the special points of reservoir protection |
