为了进一步提高文东斜坡带滚动勘探开发水平,本文重点从油气成藏条件、控制因素分析入手,对该区油气成藏规律进行了研究,结果表明:该区油气供给充足、储盖和油气运移圈闭配置良好;受构造格局和断裂活动影响,油气主要聚集在斜坡带较高的构造部位,油气富集程度明显受构造和储层发育及物性的控制;由于烃源岩热演化生烃的时空差异性导致了文东斜坡带上油下气的分布格局。并通过勘探开发部署,取得了一系列丰硕的成果。
In order to further improve the exploration and development level of Wendong slope belt, this paper focuses on hydrocarbon accumulation conditions and control factors from the analysis of hydrocarbon accumulation in this area. The results show that there is sufficient oil and gas supply, Due to the tectonic structure and the fracture activity, the oil and gas mainly accumulate in the higher tectonic parts of the slope belt, and the enrichment degree of oil and gas is obviously controlled by the structure and reservoir development and physical properties. Due to the thermal evolution of hydrocarbon source rocks The spatial and temporal differences caused the distribution of oil and gas in the Wendong slope. Through the exploration and deployment, a series of fruitful results have been achieved.
