摘要

川东北地区大量发育较好的海相碳酸盐岩储层,而海相碳酸盐岩储层在发育及油气成藏等方面表现复杂。本文通过野外调查,以蟠龙洞、通江铁厂河和羊鼓洞地区长兴组典型生物礁露头为代表并结合室内研究,在以往研究的基础之上结合现有地震资料得出长兴组沉积模式和沉积体系,认为长兴组为台盆对称沉积模式,主要发育台缘礁滩沉积体系、开阔台地(缓坡)沉积体系、浅滩-蒸发坪及盆地沉积体系,且通南巴地区广泛存在台地边缘礁滩相带,进而对长兴组储层区域进行了预测。
Large amount of good sea facies carbonate reservoir developed in northeastern Sichuan area,and showed great complexity in reservoir development and gas-oil reservoiring.This paper has concluded the sedimentary pattern and sedimentary systems by investigating outside and researching inside based on the former research,seismic information and several key biological reef outcrops of Chang Xing formation in Pan Long dong,Tie Chang he and Yang Gu dong areas,Thinking that Chang Xing formation developed mesa-basin symmetrical sedimentary pattern, including mesa fringe reef-shoal facies sedimentary system,open mesa sedimentary system,shoal-vaporizing level ground sedimentary system and basin sedimentary system.Mesa fringe reef-shoal facies belt exists largely in Tongnanba area and we have made further prediction for Chang Xing formation reservoir.
