摘要
通过构造格局研究、沉积相及储集特征研究、储集层预测评价、储集层分布发育特点、油气水分布聚集规律及影响因素分析 ,认为吉格森构造带面向生油洼槽 ,良好的沉积砂体、发育的构造圈闭与之相匹配 ,使之成为额仁淖尔凹陷的主要油气聚集带。据此指导油田滚动勘探开发 ,寻找出数百万吨地质储量 。
Through studies on a series of features in the Jigesen structural zonesuch as structural, sedimentary, reservoir property, predictive evaluation, genetic features of the reservoir beds, and control distributive trends of oil, water and gas accumulations, as well as factors, it is realized the zone is the main oil entrapment region in the Erennaor depression for its advantageous location with respect to the oil source trough in the depression and well developed sand bodies coupled well with structural heights of the traps. Successive exploration and development indicated this zone being of great oil reserves, and the structure group was discovered as a large scale oil field with up to 10 million tons of geological oil reserve.
