摘要

针对巴音都兰凹陷典型的反转型凹陷,构造与有利储集相带不匹配,地震资料品质差等不利因素,通过对构造、层序、沉积、储层等多种控油因素综合地质分析认为,由于构造反转作用,在所形成的大型鼻状或反转背斜构造背景下,阿四段高位体系域进积型扇三角洲沉积于构造的翼部,其前缘砂体夹于湖相暗色泥岩之间,在正向构造的中低部位易形成岩性圈闭。巴Ⅱ号、巴Ⅰ号和包楞构造等翼部为有利靶区,经过多期沉降、多期反转的构造演化,有利于多种类型岩性圈闭的形成,扇三角洲前缘相分流河道砂和次生孔隙发育带控制油气富集。
Bayindulan Depression is a typical reversed depression with the structure failing to match with the favorable reservoir facis belt. The seismic data of the depression are poor in quality. Based on integrated geological analysis of various oil controlling factors, such as structure, sequence, sedimentation and reservoir, it is concluded that the fan delta of A-4 section high stand systems tracts is located on the sides of the structure. The frontal sandbody is between the lake-facies dark mudstone layers. The lithologic trap is formed in the middle and lower positions of the structure of the positive direction. Ba-Ⅱ, Ba-Ⅰ and Baoleng Structure are the favorable target zones. The multi-stage subsidence and multi-stage structural reversed development are favorable to forming lithologic trap. The branch channel sand stone of fan delta frontal facies and secondary porous development belt control the oil and gas abundance.
