【摘要】 以济阳坳陷富台油田为例,研究了箕状断陷湖盆下古生界滑脱潜山的形成机制、分布规律与储集体特征、油气成藏条件,建立了滑脱潜山的成藏模式。提出了滑脱型潜山的形成受控于盆地边界的坡坪武断层,沿边界断层呈带状分布,滑脱型潜山发育不整合面型储集系统和内幕型储集系统,形成多套有效储集层。油藏的空间分布受储层的控制,各油藏在纵向上呈层状分布,各自形成独立的油水系统。平面上台阶断层控制油气的分布,纵向上储层发育程度控制油气的富集高产,潜山内幕油藏是主要的富集高产层系,并预测了济阳坳陷下古生界滑脱潜山的资源潜力及有利勘探方向。更多还原

【Abstract】 <abstract>king Futai oilfield in Jiyang depression as an example, the forming mechanism, distribution rule, reser-voir characteristic, and pool forming condition of lower Paleozoic detachment buried hill in half-graben fault depression lake basin are studied. The pool forming mode of detachment buried hill is established. It is put forward that the forming of the detachment buried hill is controlled by the sloping plateau-type fault of basin boundary which distributes as belt along boundary. Unconformable surface-type and internal curtain-type reservoir systems form several sets of effective reservoirs. Space distribution of the oil reservoir is controlled by reservoirs distributing as layers in the vertical, which each formed independent oil-water system. Step fault controlled the oil -gas distribution in plane and the development degree of the reservoir in depth controlled the oil-gas enrichment and high production. The buried hill internal curtain-type oil reservoirs are the main rich strata with high production. The resource potential and favorable exploration direction are predicted in Jiyang depression.更多还原
