华庆油田位于鄂尔多斯盆地中部,构造上属于鄂尔多斯盆地的陕北斜坡;区域内侏罗系延安组含油层系较发育,但随着勘探程度的深入,已很难发现大面积侏罗系油藏,小型隐蔽性油藏成为主要的勘探目标。本文结合华庆地区区域地质背景,以侏罗系成藏有利条件、成藏模式为出发点,总结了侏罗系隐蔽性油藏的预测思路,并筛选出6个潜在隐蔽性油藏有利建产区,为下步产能建设提供了目标。
The Huaqing Oilfield is located in the middle of the Ordos Basin and is structurally belonging to the northern slope of Ordos Basin. The Jurassic Yan’an Formation in the area is well developed. However, with the deepening of exploration, it has been very difficult to find large-area Jurassic reservoirs Small subtle reservoirs have become major exploration targets. Based on the regional geological background in Huaqing area and the advantageous conditions and reservoir-forming pattern of Jurassic accumulation, this paper summarizes the prediction of Jurassic hidden reservoirs and screened 6 potentially concealed reservoirs for favorable construction District, for the next step in capacity-building has provided the goal.
