摘要
通过对CB11C-2井动、静态资料分析认为该井高含水是产层中边水推进的结果。考虑到海上油田的施工特点,在常用堵剂的适应性分析基础上,研制开发了以聚合物为主剂,复合有机物为交联剂,含有稳定剂的冻胶类堵水剂。实验结果表明,所研制的堵剂具有成胶时间可控,胶体强度可调,良好的封堵能力等性能。立足于不动管柱组织了现场施工,取得了良好的降水增油效果。CB11C-2井堵水的成功,对在埕岛油田同类型高含水油井上实施化学堵水,提供了可借鉴的矿场实例。
Through analyzing the dynamic and static data of the well CB11C-2, the result shows that the well high-water-cut is edge water propelling in pay formation. In consideration of operation character in offshore field, the gelled plugging agents with stabilizer have been developed based on analyzing the adaptability of usually plugging agent. Experimental result indicates: the gel time of the plugging agents developed is controllable, gel strength is adjustable, the shut-off capacity is better and so on. After field application, the effect is comparatively good.
