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。
Based on the study on the distribution characteristics, lithologic assemblage, core observation, grain size analysis and seismic reflection characteristics of skeleton sandstone in the third member of the east of the Chaheji Formation, it is considered that the reservoir sand body is mainly caused by turbidity flow. The formation of turbidite is closely related to the whole process of the occurrence and development of the controlled depression (Cathay Fault) - NiuDong fault until its demise. After analysis, there are three turbidite fans in Xionggu 1-fork 39, fork 76 and fork 107-male 21 in the eastern section of the area. Due to the late compaction, three corresponding nose-shaped structures are formed, and industrial oil flow has been obtained , For the oil field yield increase is concerned, is the rolling exploration of favorable areas.
