高凝油油藏SMG可动微凝胶深部调驱技术研究与应用

摘要

In order to solve the problems of the flooded seriousness and sweep unevenness in the waterflooding development of high pour-point oil reservoirs, the performance of SMG movable microgel system is evaluated scientifically and some parameters are designed optimally, such as the size of SMG movable microgel, the injection rate, the injection concentration and so on.The field test result shows that the SMG profile control and flooding achieves the desired results.This technology bears great value to improve the development effect in the similar reserviors.%针对高凝油油藏注水开发中存在油藏水淹严重、注水波及不均等突出问题,系统开展了SMG可动微凝胶调驱体系性能评价.并对SMG调驱体系胶团尺寸、注入量、注入浓度等参数进行优化设计.现场试验结果证明,SMG调驱可以有效实现油藏深部调驱.该技术可为同类油藏进一步改善开发效果提供借鉴.
