王界油区是延长油田股份有限公司杏子川采油厂管辖区的延长组主要含油区块之一,是鄂尔多斯盆地东北缘安塞油田的一部分。本论文以含油层系长8油层为主要研究对象,采用石油地质综合评价技术及油藏描述技术,对安塞油田王界油区三叠系延长组主要含油层段长8进行砂体展布规律进行系统地研究。通过对长8地质研究,优选有利滚动评价目标区,提出勘探开发部署建议,为该区今后的勘探决策、勘探部署及其高效开发提供依据。
Wangdian Oilfield is one of the main oil-bearing blocks in Yanchang Formation under the jurisdiction of Xingzuo Oil Production Factory of Yanchang Oilfield Co., Ltd. It is a part of Ansai Oilfield on the northeastern margin of Ordos Basin. In this paper, the Chang 8 reservoir of the oil-bearing strata is the main research object. By means of comprehensive evaluation of petroleum geology and reservoir description technology, the sand body is distributed to the Chang 8 reservoir of the Triassic Yanchang Formation in the Wangdi Oilfield, Ansai Oilfield The law of systematic research. Through the study of Chang 8 geology and the favorable rolling evaluation of the target area, a proposal of exploration and development deployment is proposed to provide the basis for future exploration, exploration, deployment and efficient development of the area.
