摘要： 为研究川东北地区黑池梁台地南江东-黑池梁、镇巴地区储层特征及差异性主控因素，开展了露头及新增钻井岩心观察描述、岩石普通薄片及铸体薄片鉴定、储层物性测试、地震解释等工作。从沉积、成岩方面入手，系统对比与剖析了南江东-黑池梁及镇巴地区长兴组-飞仙关组储层岩性、储集空间、储层厚度及物性的差异性，并对其成因进行了分析。结果表明，这2个地区在储层岩性、厚度、储集性能等方面具有一定的相似性，同时也存在一定的差异，并且认为古地貌及基底断裂、成岩作用与构造作用均是造成储层差异的关键因素。该研究成果可为川东北地区下一步油气勘探提供地质依据。

Abstract: In order to study the reservoir characteristics and main controlling factors of reservoir differences in Zhenba and eastern Nanjiang-Heichiliang areas in Heichiliang platform of northeastern Sichuan Basin,the observation and description of outcrops and newly added drilling cores,identification of common and cast thin sections of rocks,reservoir property test and seismic interpretation,were carried out to systematically compare and analyze the reservoir lithology,space,thickness and properties of Changxing-Feixianguan Formation in eastern NanjiangHeichiliang and Zhenba areas from the aspects of sedimentation and diagenesis,and their causes were analyzed. The results show that the two areas have some similarities in reservoir lithology,thickness and reservoir performance,but there are also some differences. Paleogeomorphology,basement faults,diagenesis and tectonism are the key factors causing reservoir differences. The research results can provide geological basis for the next oil and gas exploration in northeastern Sichuan Basin.

Key words: reservoir characteristics, cause of difference, Changxing-Feixianguan Formation, northeastern Sichuan area
