【摘要】：本文以构造地质学、油区构造解析、沉积学、地震勘探原理和石油地质学理论体系为指导,在前人研究的基础上,利用地震、测井、钻井、录井和生产动态资料,通过井震结合和动静结合,采用切片技术、相干体技术、蚂蚁追踪技术和三维可视化技术等多种技术手段,进行构造精细解释,在几何学、运动学和动力学方面进行构造特征研究,利用定性分析和定量预测相结合完成储层预测。滨南油田滨8块整体表现为西部凹槽、中部隆起、东部斜坡的构造格局。南、北受到边界断层的控制,北部边界断层走向由近东西向到北东-南西向变化,向南倾斜,具有两段式的特点,南部边界断层走向由西向东依次为东西向、北东-南西向、东西向,向南倾斜,具有三段式的特点。内部发育多条低级序断层,东西向小断层占主导地位,受边界断层的控制,多为南倾。结合岩心、测井资料,通过单井相、连井相、平面相分析,认为该区发育三角洲相中的三角洲前缘亚相,主要包括水下分流河道、河口坝、远砂坝、前缘席状砂和支流间湾等沉积微相。结合地震属性分析和地震反演,提高了对无井地区储层认识的准确度,完善了单纯依赖井资料得出的砂体厚度和沉积相分布的结论。研究认为砂体主要分布在北部靠近滨县凸起的地带,东北部砂体最厚,中部地区砂体厚度居中,越靠近中部,断裂越发育,构造位置相对较高,是油气有利的聚集区域。
[Abstract]:Under the guidance of structural geology, structural analysis of oil area, sedimentology, seismic exploration principle and petroleum geology theory system, and based on previous studies, this paper makes use of seismic, logging, drilling, logging and production dynamic data. Through the combination of well and earthquake and static, using slicing technology, coherent volume technology, ant tracing technology and 3D visualization technology, etc., to carry out structural fine interpretation in geometry, In kinematics and dynamics, structural characteristics are studied and reservoir prediction is accomplished by combining qualitative analysis with quantitative prediction. Binan block 8 in Binnan Oilfield shows the structural pattern of the western trough, the central uplift and the eastern slope. The southern and northern boundary faults are controlled by the boundary faults. The strike of the northern boundary faults changes from near east to west to north to east to west, and tilts south to south. The southern boundary faults strike from west to east in order of east to west, and from north to south to west, and to the south from west to east, and to the north from east to south. East-west, inclined to the south, with a three-section characteristics. There are many low-order faults in the interior, and the small faults are dominated by east-west faults, which are controlled by boundary faults and tend to be southward. Combined with core and logging data, through the analysis of single well facies, contiguous well facies and plane facies, it is concluded that delta front subfacies are developed in the delta facies in this area, including underwater distributary channel, estuarine dam, far sand dam, etc. Sedimentary microfacies such as the front matting sand and the bay between tributaries. Combined with seismic attribute analysis and seismic inversion, the accuracy of reservoir recognition in no-well area is improved, and the conclusions of sand body thickness and sedimentary facies distribution obtained by relying solely on well data are improved. It is considered that the sandbody is mainly distributed in the area near Binxian uplift in the north, with the thickest sand body in the northeast. The thickness of the sand body in the central region is in the middle, the closer the sand body is to the middle part, the more developed the fault is, and the higher the tectonic position is, which is a favorable oil and gas accumulation area.
