辽河坳陷中央凸起南部潜山带具有良好的石油地质条件。针对这个地区复杂的油气成藏特点,借鉴大民屯和兴隆台潜山内幕成藏勘探的成功经验,从中央凸起构造、沉积演化特征分析入手,开展了潜山构造形态、内幕结构、输导体系、油气保存等成藏条件研究,突出断裂对圈闭形成、储集空间分布以及对油气成藏的控制作用,源-储配置关系对成藏也具有重要的影响,通过成藏特征等研究,将研究区基岩油藏划分为顶部风化壳型块状油藏和内幕层状裂缝型油藏两种油藏类型,并建立了研究区基岩立体成藏模式。
The buried hill belt in the central raised southern Liaohe depression has good petroleum geological conditions. Aiming at the complicated characteristics of hydrocarbon accumulation in this area and using the successful experience of the buried exploration of Damintun and Xinglongtai buried hills, this paper starts with the analysis of the characteristics of the salient structure and sedimentary evolution of the central buried hill, Conducting system and oil and gas reservoirs. The research focused on the formation of traps, the spatial distribution of reservoirs and the control over hydrocarbon accumulation, and the relationship between source and reservoir has an important influence on the hydrocarbon accumulation. Through the characteristics of reservoir formation and so on In this study, two types of reservoirs are classified as top-weathered crust-type reservoir and inside -rock-type fractured reservoir, and three-dimensional bedrock formation model of the study area is established.
