【摘要】 以东西伯利亚南部最大碳酸盐岩油气田尤罗伯钦—托霍姆油气田为例,采用地质、地球物理等多种基础资料,在GIS系统支撑下,运用多元信息综合分析方法,从裂缝的成因、发育规律等方面开展碳酸盐岩油田多尺度裂缝信息的综合研究。利用地震资料圈定里菲系储层局部发育带,对不同尺度来源的构造裂缝进行裂缝发育带预测。对里菲系裂缝性储层进行了综合评价,确定储层评价因子分级原则,建立影响储层发育的多因子裂缝信息数据库,运用空间分析模型建立主题图件,进行拓扑运算及成图等工作。在上述工作的基础上,进行高产区预测,实现了不同尺度和空间关系的多元裂缝信息的综合分析。多元裂缝信息综合分析方法的优势在于,可最大化地集合各种裂缝信息,建立海量相关数据库,快捷方便地进行信息提取、检索、对比和主题空间分析,充分结合油气田本身的地质特点、专家智慧,去伪存真,优化裂缝信息,高效率地为油田实际生产服务。更多还原

【Abstract】 The study is focused on the largest carbonate rock oil and gas field in the southern part of East Siberia-Yurubcheno-Tokhomskoye Oil and Gas Field.Based on geological and geophysical data and backed by GIS system,the study adopts the comprehensive analysis method for multi-element information to scrutinize the information on the fractures of different sizes in the carbonate rock oil field in the light of fractural origin and development laws.The seismic data are used to identify regional Riphean reservoir development zone and predict fractural development zones caused by structural fractures of different sizes.The Riphean fractural reservoir is brought under comprehensive evaluation for the purposes to determine the principle for classification of reservoir-appraising factors,establish the database of multielement fracture information that influences reservoir development,build thematic map by means of space analysis model,and conduct topological calculation and drawing.The high-yield zone is predicted on the basis of the above-mentioned work in the efforts to make a comprehensive analysis of the information on multi-element fractures of different sizes and space relations.The advantages of this method are to maximize collection of various fractural information,establish a magnitude database of relative information,and facilitate rapid selection and comparison of information and thematic space analysis.This study makes full use of geological characteristics of oil and gas fields and wisdom of experts and optimizes fractural information to effectively serve actual production of oil fields.更多还原
