【摘要】 碳酸岩潜山地层结构复杂、非均质性强,油气分布明显受其内幕地层产状控制,特别是对于那些规模相对较小的低潜山储集体,地震资料通常难以较准确的刻画其内幕地层的结构特征。以辽河油田曙103区块低潜山为例,提出了在地震勘探落实潜山形态的前提下,应用岩石地层学、测井地质和构造地质学原理恢复潜山内幕地层产状的分析方法,为深入研究潜山油气藏特征提供了有效途径。更多还原

【Abstract】 Due to complicated stratigraphic structures and strong heterogeneity of burial hill carbonate reservoirs,hydrocarbon distribution is obviously controlled by the interior attitudes of the strata.Especially for those small sized hills,it is usually difficult to characterize the interior structures based on seismic data.This paper,taking Block Shu103 in Liaohe oilfield as an example,has proposed a comprehensive method to resume the interior attitude of strata for burial hills when the burial hills geometry has been determined according to seismic exploration.For this method,lithostratigraphy,logging geology and architectonic geology are used,and this analytical method can be effective for the study on the characteristics of burial hills reservoir.更多还原
