摘要
在常规岩心流动试验的基础上,采用多功能万能显微镜先进技术,对辽河油田洼38块进行了钻井完井液与储层配伍性的研究。该项研究的特点是从宏观深入到微观,在模拟地层温度下观察动态变化的全过程。8种常用钻井完井液的研究结果表明:油基体系的配伍性最好,NH_4—PAN聚合物体系和CMC—FCLS体系配伍性较好,其它体系的配伍性均差。本工作为优选钻井完井液体系,保护好储层提供了依据。
The compatibility of well completion fluid to Wa-38 reservoir is studied by normal core flow test and all-powerful microscope . The advantage of this method is observing the whole dynamic course of fluid invasion . Test results of 8 kinds of fluid are : oil based system is the best , NH4-PAN polymer system and CMC-FCLS are good , and others are not ideal for reservoir protection .
