摘要
从中国石油水平井生产简况、应用的油藏类型、完井方式、出水类型及产水危害等几个方面介绍 了水平井堵水的背景,从水平井底水脊进机理、堵水剂、堵水工艺的研究以及油藏动态研究、水平井产 出剖面测试、新型化学剂、物理模拟实验等方面论述了水平井堵水的现状及存在的问题,指出水平井堵 水技术研究重点是选择性堵水剂和选择性注入工艺。
The background of water shutoff in horizontal well is introduced from the aspects of China s horizontal well production situation, reservoir types of application, modes of well completion, type of water production, and the damage of water production, the current situation and problems of water shutoff in horizontal wells are denoted from the aspects bottom water coning mechanism in horizontal wells, water plugging agent, its plugging process study, dynamic reservoir study, the measurement of the well production profile, new chemical agents and physical simulation experiment. It is pointed out that the focus of water shutoff technique is to use a selective plugging agent and injection process.
