海拉尔盆地乌尔逊—贝尔凹陷岩性一地层油藏成藏特征及勘探方向
Forming characteristics of iithologic and stratigraphic reservoirs and its exploration direction of Wurxun-Beir sag in Hailar Basin
摘要
Abstract
Wurxun-Beir sag is the mainly area of oil and gas exploration in Hailar Basin. Its exploration of lithologic and stratigraphic reservoirs is low degree and has a great potential of residual hydrocarbon resources. The research on reservoir forming characteristic indicate that there are three sets of regional source rocks, six depositional systems, three types reservoirs and many abnormal high porosity zone and develop multi-phase structural movement and depositional break and contains three source-reservoir-caprock assemblages. These properties offer the favorable geological condition for forming the lithologic and stratigraphic reservoirs. Based on the origin and geometry of traps, the lithologic and stratigraphic reservoirs are divided into three types of lithologic reservoir, stratigraphic reservoir and compound reservoir. The lithologic and stratigraphic reservoirs concentrate in the edge of trough belt, large slow slop fold belt,lower uplift in trough belt and terrace fault steep slop fold belt and distribute around the source trough and appear half-annularity. According to forming characteristic and distributing rule of the lithologic and stratigraphic reservoirs, the favorable play and exploration direction were predicted by comprehensive analysis method. Three full-scale the lithologic and stratigraphic reservoirs were founded by drilling. The distinct exploration benefits were obtained.关键词
