| 摘 要： | 在绥中36－1油田，钻井液滤液，水泥浆滤液和碱性完井液之间配伍性能，相互接触时产生大量沉淀，导致岩心渗透率下降，损害储层，研究了一种稳形酸完井液，该完井液由过滤海水或过盐水，粘土稳定剂HCK和稳表酸螯合剂HTA组成，该完井液能够在井下释入H^ ，对前期钻井，固井作业时各种滤在地层中产生的沉淀具有良好的消除作用，对滤液间产生的无机沉淀和有机沉淀具有良好的溶解作用，同时能够防止海水及地层水中的新的钙，镁沉淀的形成，经绥中36－1油田应用表明，隐形酸完井液明显地提高了比采油指数，降低了表皮系数，提高了油井产量。

| Abstract: | The incompatibilities among drilling filtrate, cement slurry filtrate and basic completion fluid filtrate in Suizhong 36-1 Oilfield result damage to oil-gas reservoir, and implicit acid completion fluid is developed. The fluid is composed of filtrated saltwater, clay stabilizer HCS and chelating agent HTA. H can be released downhole and sediment could be eliminated or prevented effectively. Field using in Suizhong 36-1 Oilfield shows that the fluid increase the productivity factor, reduce the skin factor and the production is increased. |
