摘要

本文根据洪德地区岩芯、录井、测井解释及动态资料综合研究了沉积环境与储层物性,认为该地区长6储层为特低孔-超低渗储层类型致密砂岩储层,沉积相为三角洲前缘亚相沉积,可细分为水下分流河道、河口坝和水下分流间湾3种沉积微相。结合试油数据、含油性录井资料,将储层划分为三个等级,并选出15个Ⅰ类有利储层、13个Ⅱ类有利储层和7个Ⅲ类有利储层。
        Based on the core, logging, logging interpretation and dynamic data of Hongde area, the sedimentary environment and reservoir properties are studied comprehensively. It is believed that the Chang 6 reservoir in the area is a tight sandstone reservoir of ultra-low porosity-ultralow permeability reservoir type. The sedimentary facies are sub-facies of the delta front, which can be subdivided into three sedimentary microfacies:the underwater distributary channel, the estuary dam and the underwater diversion bay. Combined with oil test data and oil-bearing logging data, the reservoir is divided into three grades, and 15 Class I favorable reservoirs, 13 Class II favorable reservoirs and 7 Class III favorable reservoirs are selected.
