我们在石油地质工作中的主要研究对象是沉积岩石层。因而,在普查和勘探过程中,首先要正确地建立地层层序和进行地层划分、对比工作。同时,对组成各该岩层的沉积物质及其特征必须详细研究,以便进一步了解它们之间的相互关系和在空间、时间上的变化规律性;探索它们在特定地质条件下可能形成的生油岩、储油岩及盖层情况;研究它们的岩相古地理特征。并结合地质构造等因素,对普查勘探地区进行含油气远景的正确评价;指导进一步勘
Our main research object in petroleum geology is sedimentary rock layers. Therefore, in the census and exploration process, we must first correctly establish stratigraphic sequence and stratigraphic division, comparison work. At the same time, it is necessary to study the sedimentary materials and their characteristics which constitute each rock formation in detail in order to further understand the relationship between them and their regularity in space and time; explore the possible source rocks that they may form under certain geological conditions , Oil-bearing rocks and cap rocks; and studying their lithofacies palaeogeographical features. Combined with the geological structure and other factors, the prospect of petroleum exploration in the census area of the correct assessment of the future; guidance for further exploration
