摘　　要：随着黄骅坳陷勘探程度不断提高,在盆地内正向构造带寻找构造油气藏的难度日益加大,斜坡区岩性油气藏越来越受到研究人员的重视。基于黄骅坳陷斜坡区实际勘探实践,在斜坡区油气藏类型和分布的基础上,结合斜坡区油源条件、砂体发育机制、砂体与断层耦合关系等,明确了斜坡区油气富集高产主控因素。研究表明,斜坡不同部位油气富集高产主控因素不同斜坡高部位源-砂耦合控藏,优势砂体高产;斜坡中部位断砂耦合控藏,优势储层高产;斜坡低部位优势组构控藏,地质工程甜点高产。进而提出了斜坡区常、非连续成藏和差异富集高产模式,即油气藏在富油凹陷整个斜坡区连续分布,高斜坡主要发育常规油藏,中斜坡为过渡带,常规油藏、致密油藏及页岩油藏都有分布,低斜坡主要为页岩油藏。With the deepening of exploration in Huanghua Depression,it gets more difficult to find structural reservoirs in uplift area inside the basin,and lithologic reservoirs in slope area are paid more and more attention by researchers.Based on the exploration practice and the types and distribution of oil and gas reservoirs in the slope area of Huanghua Depression,combined with the oil source condition,sand body development mechanism and the coupling relationship between sand body and fault in the slope area,the main controlling factors of hydrocarbon enrichment and high yield in the slope area are clarified.It indicates that main controlling factors of hydrocarbon enrichment and high yield differ in different parts of the slope.Reservoirs in the higher part of the slope are coupling controlled by source and sand body,rich in dominant sand body.Reservoirs in the middle part of the slope are coupling controlled by fault and sand bodies,rich in dominant reservoirs.In the lower part,reservoirs are coupling controlled by dominant formation and structures,rich in favorable spots of geological engineering.Furthermore,the high-yield model of conventional and discontinuous accumulation and differential enrichment in slope area is put forward,in which hydrocarbon reservoirs are continuously distributed in the whole slope area of the oil-rich sag.Conventional reservoirs are mainly developed in the higher slope,conventional,tight and shale reservoirs are distributed in the middle slope,a transitional belt.Shale reservoirs are mainly developed in the lower slope.
