摘　　要：利用三维地震解释、储层反演和相干数据体新技术 ,结合野外露头、地质、测井、钻井及生产动态等资料 ,对酒西盆地鸭儿峡志留系油藏的构造形态 (尤其是次一级构造 )、断裂系统、裂缝控制因素及发育区带、水体分布及运动规律、油气聚集特征及剩余油分布进行深入研究。研究结果认为 :油藏的油气聚集主要受构造高部位、断层、裂缝发育、岩性 4大因素的控制 ;潜山顶部 ,白云岩分布区、侵入体拱起区的次一级构造高部位 ,是油气聚集的有利区 ,也是目前剩余油富集区。Using 3D seismic interpretation, reservoir inversion and the new technique of coherent data, and combining with field outcrop, geology, logging, drilling and production performance data, deep study had been carried out for the structure (especially primary structure), fault system, dominated factors of fractures and its development belt, distribution and movement law of water, oil and gas accumulation features, and distribution of residual oil in Silurian reservoir of Yaerxia, Jiuxi basin. The result of this study was that, oil accumulation was mainly controlled by structure high, fault, fracture development, and lithology these four major factors; favorable areas of oil and gas accumulation were structure high of the main body of buried hill, and sub structure highs of dolomite area and the arching part of intrusive body, where were also abundance zones of residual oil.
