摘要
介绍了MMH钻井液体系的特点及其在保护储层方面的作用。MMH钻井液体系用大理石或大理石和重晶石组合加重时,其渗透率恢复值高于盐粒液和油基钻井液体系,是一种优良的保护油层钻井液体系。按照设计完井液的思路,根据单一处理剂评选结果,给出了5种完井液配方,并简单分析了MMH钻井液体系保护油层的作用机理。
The advantage and reservoir protecting function of MMH drilling fluid are presented . It is shown that return permeability of MMH drilling fluid weighted by marble or marble/ barite is higher than those of sized salt system and oil based mud . MMH is a good system for reservoir protection . Five well completion fluid compositions of MMH are given .
