| 摘 要： | 根据在大港油区部署的水平井地层特点以及对钻井完井液的技术要求,形成了BH-FDC无固相储层专打钻井完井液.该钻井完井液的基液为复合盐水,具有很低的水活度,可以使岩石中的水渗流入钻井液,加上离子交换作用,使钻井液具有很强的抑制性,同时该体系无固相,不含二价或二价以上阳离子,与地层水的配伍性好,因此该钻井液既能保证水平井井壁稳定,又能减少对储层的损害.该钻井完井液在港71-1H等10口井进行了应用,施工结果表明,该钻井完井液配方简单,维护方便,可以在裸眼段直接进行体系转换,减少了一层套管的下入,节约了钻井周期;现场取样检测该钻井完井液的平均渗透率恢复值达91.03%,10口井投产均获高产油流,实现了免酸洗投产目标,缩短了生产时效,降低了施工成本,取得了良好的经济效益和社会效益.

| Abstract: | BH-FDC,the solid-free drill-in fluid only used for reservoirs is developed for the horizontal wells in Dagang oilfield.Taking combined salt water as base fluid,BH-FDC has low activiey so water in rock seep into drilling fluid,and has good inhibition because of ion exchange.Without solid or bivalent ions,BH-FDC has good compatibility with formation water and good effect on borehole stability and reservoir protection.The application in 10 wells shows that BH-FDC can be transformed in open hole so as to save o... |
