摘　　要：通过对鄂尔多斯盆地陕北斜坡中部长63砂组沉积体系研究,在成岩作用和沉积作用研究的基础上,对工区长63砂组的储层进行了评价。通过沉积体系研究、储层评价、构造分析及已发现油层平面展布图等4图叠加,结合工区的成藏条件和成藏因素分析,查明了研究区长63砂组的有利勘探区域,认为6-1R岩性圈闭和6-2R岩性圈闭及6-3背斜构造和6-4鼻状构造是有利的勘探区。By studying the depositional system in Chang 3 Sand Group, the reservoirs in Chang 63 Sand Group were evaluated on the basis of diagnosis and depositional study. Through the study of the depositional system evaluating the reservoir quality of the Chang 63 Sand Group,and congruence, the maps of depositional system are discovered, in combination with the analyses of reservoir forming condition and the reservoir forming factors, the favorable oil exploration area in sand group is clarified, it is considered that the 6-1R ,6-2R lithological traps, 6-3 anticline structure and 6-4 nose structure are the favorable exploration plots.
