摘　　要：车镇洼陷北带的沙四上—沙三下亚段,发育有多类型、多期次砂砾岩扇体,是油气运移的主要指向。通过解剖典型探井,对不同扇体的发育类型、沉积特征、成藏控制因素进行分类总结,归纳出针对不同砂砾岩扇体的研究技术思路和方法,并在实际生产中得到验证,为类似地区的研究提供了方法和借鉴。Glutenite fans of various types and stages had developed in upper s4-lower s3 of north Chezhen sag,where was the main direction of hydrocarbon migration.This paper studies typical exploration wells and generalizes the types,sedimentary characteristics and controlling factors of hydrocarbon accumulation of various fans,and sums up the methods of study for different glutenite fans.This method has been verified through practical application and provides a reference for other similar areas.
