| 摘 要： | 辽宁绥中36-A油田是渤海海域亿吨级的大油田,古近系含油气层段主要集中在东二段.本文通过理论和实际相结合,物探和地质相结合,微观和宏观相结合,勘探和开发相结合,详细分析了该区东二段储层微观特征及其主控因素:东二段发育湖泊三角洲前缘亚相的有利储层相带.同时综合分析成岩作用,粘土矿物含量,温压场及流体充注等几个影响物性的重要方面,认清了该段发育侧向展布范围广、纵向厚度大,高孔高渗优质储层的根本原因.

| Abstract: | The 36-A Oil Field in Suizhong, Liaoning is a hundred million ton-sized oil-gas field in the Bohai offshore field. The Palaeogene oil reservoirs are mainly concentrated in the second member of the Dongying Formation. The present paper deals in detail with the microscopic features and controls of the hydrocarbon reservoirs in the study area. The favourable reservoirs are mainly organized in the lacustrine delta front subfacies in the second member of the Dongying Formation. The diagenesis, clay mineral content, temperature-pressure field and fluid filling as main controlling factors of the physical properties of the oil reservoirs are believed to be responsible for the devolopment of vast extensive distribution, tremendous vertical thickness, high porosity and high permeability favourable reservoirs. |
