摘要
有效烃源灶的展布决定了油气勘探的领域,根据辽河西部凹陷西斜坡中南段油气成藏背景及分布特征,分析了辽河西部凹陷西斜坡中南段发育的两套有较高丰度的烃源岩,该区烃源岩具有烃源岩厚度大,有机质丰度高,类型优的特点。烃源岩存在3个沉积中心内。从目前已发现的油气藏特点来看,烃源灶控制油气分布范围,输导体系控制油气分布格局,烃源岩直接盖层控制油气富集,围绕这些烃源灶周边发育的有利聚集单元内是油气勘探的有利目标区,这一结论在鸳鸯沟地区的钻探中得到了验证。
The distribution of effective hydrocarbon kitchen determines exploration of oil and gas field. According to the background and the distribution characteristics of oil and gas reservoir on middle south of the west slope in Liaohe western sag, analysis of two sets hydrocarbon source rocks that having high abundance development, the hydrocarbon source rocks of the area with the big thickness, high organic matter abundance, types of superior characteristics. Hydrocarbon source rocks exist 3 sedimentary center. From the characteristics of the discovered oil and gas reservoir, hydrocarbon kitchen controls the range distribution of oil and gas, the grooming system controls the patten distribution of oil and gas, direct cap rock of hydrocarbon source rocks controls oil and gas accumulation, favorahle development around the surrounding these hydrocarbon kitchen gathering unit is favorable target areas for oil and gas exploration, this conclusion in Yuanyanggou area of drilling has been verified.
