喇嘛甸油田不同类型储层水洗状况评价

The evaluation of different period water washing condition for Lamadian Oilfield

喇嘛甸油田经过近30多年的开发调整,各类储层水洗状况较为复杂。本文应用喇嘛甸油田不同时期10口密闭取心检查井资料,对不同类型储层的水洗状况、剩余油分布特点进行了系统地评价,为油田聚驱上下返、三次加密调整工作、水驱综合调整提供准确的地质依据。

Lamadian Oilfield has been developed for 30 years, the water washing condition of oil zones is relatively complex. In this article, the water washing condition, remaining oil distribution characteristic of different period oil zones style, sedimentary microfaees, thickness classification and the injection-production relation are systemic evaluated by applying different period ten sealed core examing well data in Lamadian Oilfield. It provides exact geology evidence for up and down-return zones of polymer flooding and the tertiary oil recovery encrypt adjustment.
