根据室内试验结果,评价各种滤液之间的配伍性及对储层的损害程度,同时研究了钻井液和水泥浆对储层的综合损害。在此基础上,提出用屏蔽式暂堵技术改造油田现用PEM钻井液的方法,这对提高油田产量具有重要的现实意义。
According to the indoor test results, the compatibility between various filtrates and the degree of damage to the reservoir were evaluated. At the same time, the comprehensive damage of drilling fluid and grout to the reservoir was studied. On this basis, it is proposed that the temporary plugging technology should be used to transform the existing PEM drilling fluid in the oilfield, which is of great practical significance to improve oilfield production.
