| 摘 要： | 川东北三叠系飞仙关组储层为一套鲕粒细晶白云岩、细晶白云岩、生屑细晶白云岩,经后期成岩作用和构造运动的作用改造而成,溶孔(洞)和裂缝十分发育。根据层序地层学的基本原理,结合大湾区块飞仙关组取心井岩心、测井等数据,对典型剖面进行了分析研究。大湾飞仙关组可划分出2个三级层序、7个四级层序和16个五级层序。研究区内层序控制不同沉积的发育,沉积相控制有利储层的展布范围。有利沉积相带位于三级层序的高位体系域中,鲕粒滩微相的鲕粒细晶白云岩为最有利岩相,溶蚀较发育,物性最好。

| Abstract: | This paper on Dawan block coring wells, the author analysis of the typical profile use rock cores and logging data. The results show that the Feixianguan formation of the study area can be divided into two third-order sequence. Sequence of coherence can be compared. Sequence control different deposition,Sedimentary facies control the range of favorable reservoir distribution. Favorable sedimentary facies on the third-order sequence of HST, oolitic facies of the oolitic fine grained Dolomite is the best reservoir rock, corrosion growth, physical best. |
