| 摘 要： | 山东东辛油田古近系沙河街组一段湖相碳酸盐岩过去仅作为盖层而忽视其油气地质意义。研究表明,其岩性以生物灰岩及鲕粒灰岩为主,并有少量螺灰岩。其中生物灰岩中以溶蚀孔隙、生物体腔孔及骨架孔隙等类型构成主要的油气储集空间,使其具有较高的孔渗性;鲕粒灰岩在形态上以长条鲕、圈层鲕最为常见,其核心以生物碎片(化石)为主,鲕粒灰岩以粒间孔和粒内孔作为主要的油气储集空间,亦具有较高的孔渗性。沙一段碳酸盐岩的主要矿物成分为白云石和方解石,且大部分白云石及部分方解石均含铁,不同岩性的储层具有不同的储集类型,储层性质受岩石类型、沉积环境、表生作用及胶结作用、溶解作用及白云岩化等成岩作用影响,且沙一段储层处于油气运聚非常有利的过渡带,在藻滩及高能浅滩部位可形成较好的油气富集带,所以对湖相碳酸盐岩储层的研究有助于老区滚动勘探开发。 |

| Abstract: | Lacustrine carbonate rocks in member 1 of Shahejie Formation consist of biolithitic and oolitic limestone and minor ancylus fluviatilis limestones.Biolithite,made up of stratums with bio-fragment and fossils,have admirable pervasion ability,in which dissolve pore,organism pore and framework pore play important roles in preserving oil and gas;In general oolitic deposits were formed in shallow and high energy surroundings,and usually the elongate and loop oolites with biogenic cores(predominate.) As an excellent reservoir rock, oolite limestones have excellent pervasion ability and are incarnated in intergranular pore and inner pore.Rocks of Member 1 of Shahejie Formation were formed by various processes of cementation,dissolution and dolomitization under favorable conditions. |
| Keywords: | member 1 of Paleogene Shahejie Formation lacustrine facies carbonatite biolithite limestone ooide limestone reservoir |
