应用射线追踪技术预测大民屯凹陷油气运移路径与聚集区

The predication of hydrocarbon pathway by the way of ray-tracing technique

油气运移路径的研究一直是石油地质学研究的难点。近年来发展起来的射线追踪技术则基于油气二次运移的相对能量行为,将生烃凹陷与能量场结合起来,是对流体势分析技术的重要改进和实现油气藏定位预测的重要途径。油气运移的射线追踪技术在大民屯凹陷的应用结果表明:模拟结果与实际油气分布情况吻合较好;高蜡油分布范围较广,静西构造带是高蜡油的汇聚场所之一,具有重要的勘探潜力;正常油分布范围相对局限,仅分布在南部荣胜堡洼陷及其周边地区。

The study on the hydrocarbon pathway always is the nut of petroleum geology.The newly developed ray- tracing technology which integrate hydrocarhon kitchen and energy field is much improved comparing with the flu- id potential analyze,so it is an important technique of res- ervoir location.The application of ray-tracing technique on the Damingtun depression shows that:the modeling: results tally with the distrihution of hydrocarbom high- waxy oil is widely occurrence.Jingxi structural heh is the gathering place of high-waxy oil,which is exploration prospect;the normal oil is relative narrowly occurrence, which mainly distribute in the Rongshengpu sag and its perimeter zone.
