摘　　要：对车拐斜坡区三叠系百口泉组沉积相目前存在的认识不统一、有利储层分布范围认识不清等问题进行分析,综合利用目前完钻井的录井、测井、岩样的化验资料及三维地震属性技术,认为三叠系百口泉组整体经历了一个气候由干旱到潮湿,沉积水体由浅到深的湖侵沉积演化过程。研究区主要发育扇三角洲平原、扇三角洲前缘、滨浅湖3种亚相,三支扇体之间为扇间洼地,向凹陷逐渐过渡为扇三角洲前缘,凹陷中心为滨浅湖沉积。扇三角洲前缘储集岩孔隙度及渗透率较好,为最有利的沉积相带。The understanding of the Triassic Baikouquan formation sedimentary phase is not unified,and the favorable reservoir distribution range haven＇t a clear understanding,based on these problems in cheguai slope of Junggar basin, us- ing the drilling data and 3D seismic attribute technology,we consider that Triassic Baikouquan group went through a whole process of a climate from arid to humid and sedimentary water changed from shallow to deep.The study area Mainly developed such 3 kinds of subfacies：fan delta plain,fan delta front and shore-shallow lacustrine.Among the 3 kinds of fans,there are depressions,gradually transitions to the the fan delta front,the center of the depression is the shore-shallow lacustrine.The porosity and permeability of fan delta front is better,which is the most favorable sedimenta- ry facies.
