【摘要】：府村区内勘探与研究程度均较低,对各油层组的沉积相展布、砂体发育的时空分布规律、储层性质以及成藏规律缺乏系统性的研究,制约了该区石油勘探进程。通过本文研究，，明晰府村地区油气成藏条件和今后的勘探方向。本文在文献调研、熟悉和了解工区钻测井和分析化验等资料的基础上,综合应用岩心、钻测井以及分析化验、测试等资料,从单井地层划分出发,在沉积微相、储集物性特征、四性关系研究及油气成藏条件和主控因素分析基础上,评价工区的油气富集规律。本文明确了构造-岩性复合圈闭油气藏为府村探区内主要油气成藏类型。长2油藏平面上受西倾单斜构造背景的控制,低幅度鼻凸控制油气分布；长6-长8油藏的形成和分布主要受沉积微相、盖层条件和储盖组合、鼻状隆起背景等多重因素控制,其中沉积微相和储层物性对本区油气分布的控制作为更为明显。
[Abstract]:The degree of exploration and research in Fucun area is relatively low. There is a lack of systematic research on the distribution of sedimentary facies, the temporal and spatial distribution of sand body development, reservoir properties and reservoir formation, which restricts the process of petroleum exploration in this area. On the basis of literature investigation, familiarity and understanding of the data of drilling and well logging and analytical testing in the working area, this paper comprehensively applies core, well logging, analysis, testing and other data, and so on, in order to clarify the oil and gas reservoir formation conditions and the future exploration direction in Fucun area. Based on the stratigraphic division of single well, on the basis of the study of sedimentary microfacies, reservoir physical characteristics, four-sex relationship, oil and gas reservoir forming conditions and main controlling factors, In this paper, the main oil and gas accumulation types in Fucun exploration area are identified as tectonic-lithologic complex traps. Chang2 reservoir is controlled by the westerly inclined monoclinal tectonic background and controlled by low amplitude rhinoconvex on the plane of Chang2 oil and gas reservoir, and the distribution of oil and gas is controlled by low amplitude nasal protrusions in Fucun exploration area. The formation and distribution of Chang 6-Chang 8 reservoir are mainly controlled by many factors, such as sedimentary microfacies, caprock conditions, reservoir cap assemblage, nose uplift background and so on, among which sedimentary microfacies and reservoir physical properties control the distribution of oil and gas in this area more obviously.
