摘要
充分利用地层倾角技术、高分辨率相干加强技术等技术,落实车镇南坡下古生界潜山构造特征,探讨潜山油气运移模式及成藏规律。研究表明:车镇南坡下古生界发育的10排潜山;其中,1-8排山由反向断层控制,9-10排山由顺向断层控制。建立三种潜山油气运移模式:源山对接型、不整合面型和内幕疏导型,相应地发育了三种油藏类型:风化壳油藏、地层油藏和潜山内幕油藏。潜山也同样具有断层分割油藏的特点,反向遮挡断层断距与含油高度正相关,反向断层断距越大,侧向遮挡越好,含油高度越大。研究结果可为潜山油气藏勘探开发提供参考。
This paper intends to make full use of stratigraphic dip technology and high-resolution coherent strengthening technology to realize the structural characteristics of the Lower Paleozoic buried hill on the south slope of Chezhen,and discuss the oil and gas migration model and reservoir-forming law of the buried hill.The study shows that there are 10 buried hills developed in the lower Paleozoic in the south slope of Chezhen,among which 1-8 is controlled by reverse fault and 9-10 is controlled by forward fault.Three oil and gas migration models of buried hill are established:source mountain docking type,unconformity surface type and insider dredging type.Accordingly,three reservoir types are developed:weathering crust reservoir,stratigraphic reservoir and buried hill insider reservoir.The buried hill also has the characteristics of fault segmentation of the reservoir.The reverse shielding fault distance is positively related to the oil-bearing height.The larger the reverse fault distance is,the better the lateral shielding is and the greater the oil-bearing height is.The research results can provide reference for the exploration and development of buried hill reservoir.
