| 摘 要： | 辽中凹陷沙河街组及部分东营组储层埋藏深度大及储层物性变化大的特点制约了中深层油气的勘探；通过分析沉积相、储层组成特点、成岩作用、异常高压、油气充注等对储层物性的控制．提出了中深层存在次生孔隙发育带，其形成主要源于岩屑长石砂岩中长石、碳酸盐岩胶结物、岩屑的溶蚀以及超压和早期油气充注对储层的保护。 |
| 关 键 词： | 辽中凹陷 古近系 中深层储层 主控因素 成岩作用 次生孔隙 |

| Abstract: | The exploration of mid-deep oil and gas is constrained mainly by reservoir petro-physical changes of deep Dongying and Shahejie Formations. The petrophysical controlling factors, which include the sedimentary facies, reservoir compostion characteristics, diagenesis, overpressure, early oil and gas injection are discussed, then it is predicted that there exist secondary pore zones in the mid-deep reservoirs, which are derived from the protection of the feldspar, carbonate cement, debris and the protection of the overpressure and early oil and gas injection. |
| Keywords: | Liaozhong Depression Paleaogene mid-deep reservoir main controlling factor diagenesis secondary pores |
