王场油田北断块精细地质研究实践与认识

Practice and Cognition of Fine Geological Study on North Fault Block of Wangchang Oilfield

王场油田北断块经过多年的开发,已进入中高含水的开发中后期,但是有进一步提高采收率的潜力。从进一步提高采收率的角度出发,开展了三个方面的精细地质研究:研究薄隔层展布规律、研究储层特征、精细描述剩余油分布。成果目前应用成效显著,最终达到了提高采收率的目的,对同类油藏持续稳产有一定的借鉴作用。

Although Wangchang Oil Fields north fault block has gone into high water cut stage due to over years of development, there is potential to improve its recovery. To reach the aim, this paper conducted fine geological research from three aspects, that is, research on spreading pattern of thin interlayers, on character of reservoir and fine description of remaining oil distribution and finally achieved higher recovery rate of crude oil. The result provides experiences for the same practice to other reservoirs of the same kind.
