摘要
分析了塔里木 LN地区的储层特征。根据分析结果 ,在该地区采用 MMH正电胶钻井液体系 ,并加入暂堵剂 JHY和 QS- ,以起到屏蔽暂堵作用。该体系具有较好的流变性、抑制性 ,与地层水的配伍性较好 ,保护油气层效果好。动、静态损害评价试验表明 ,在岩心 4～ 6cm段 ,动、静态损害评价试验测得的渗透率恢复值均大于 90 %。
The reservoir characteristics and its potential damage in LN region of Tarim basin are analyzed The results from analysis shows that the positive electric colloidal drilling (MMH) in addition of JHY and QS Ⅱ is deployed to carry out temporary shielded plugging The fluid is characterized by good rheology and inhibitive property, proper compatibility with formation water,high efficiency of reservoir protection Both dynamic and static damage evaluation tests on 4 6 cm core show that the restoration rate of permeability is above 90%
