The Turbidite Found in Chaxi Area and Its Importance for Exploration Petroleum
-
摘要: 通过对岔河集西部地区东三段的骨架砂岩分布特征、岩性组合、岩芯观察、粒度分析和地震反射特征等研究,认为储油砂体主要为浊流成因。浊积岩的形成与控凹断层—牛东断裂的发生、发展直至消亡的全过程密切相关。经分析该区东三段存在雄古1岔39、岔76及岔107雄21三个浊积扇,由于后期差异压实作用形成三个对应的鼻状构造,均已获得工业油流,对于油田的增储上产来讲,是进行滚动勘探的有利地区。Abstract: By studying the distribution characteristics, lithologic assemblages, core features,grain size analysis and seismic reflectance of skeleton sandstone of D Ⅲ interval in Chaxi area,it is regarded that the reservoir sandstones was mainly the result of turbidity and the turbidite measure was connected with the whole event of the fault controlling sag—Niudong fault origin,evolution and extinetion. There are three turbidity fan (Xionggul-Cha39,Cha76 and Cha107-Xiong21)in the area by analysis. Because of late differential compaction,they belong to three structural nose respectively and all have gained commercial oil and gas. For the Sake of increasing reserves and production,they are the best area for the roll-over exploration.
