摘　　要：碳酸盐岩油藏在开发过程中,由于油井的出水造成了产量的大幅度减少。对于碳酸盐岩油藏,堵水已成为改善油田开发效果、增产稳油的重要措施之一。首先,对国内外常用的化学堵水工艺及其堵水机理进行了详细介绍,目前,化学堵剂依然以聚合物堵剂和凝胶堵剂为主。其次,以 M 碳酸盐岩油田为例,对 M 油藏的堵水情况进行了简单介绍,通过与堵水效果有关的碳酸盐岩储集层、完井方式、见水类型、堵水方式、采出程度和堵前含水率 6 个方面,对堵水有效性进行了评价。In the process of developing the carbonate reservoir, water breakthrough resulted in a substantial reduction of the well production. For carbonate reservoirs, The water shutoff has become one of the most important measures to improve the effects of oilfield develop- ment and increase the production. Firstly, the commonly chemical water shutoff technology in the domestic and foreign has been described in detail. Currently, Chemical blocking is still based on polymer and Gel. Secondly, taking the M carbonate reservoir for exzample, The water shutoff of the M carbonate reservoir has been briefly introduced. Through the reservoir strata, the well completion method, the waterbreakthrough type, water control methods, the recovery degree and the moisture content before plugging in six aspects, we evaluated effec- tiveness of the water shutoff technology.
