摘　　要：构造地质成因分析,在油气田开发中具有十分重要的作用。文章从国内外研究现状入手,在文献调研基础上详细对比了油气田开发中构造地质成因分析的优缺点。总结了构造地质成因分析研究内容:(1)通过构造演化历史分析和地应力场等研究,确定断裂体系构造地质成因。(2)井震结合开展精细的构造解释,分析构造地质成因。(3)对构造地质成因研究方法进行探索和改进。(4)综合动静态资料,开展储层地质成因分析。(5)与沉积相研究和成岩作用研究等紧密结合。(6)加强地质成因分析成果应用,为油气田开发提供基础。(7)裂缝表征和建模。(8)微构造地质成因分析。油气田开发中构造地质成因分析的方法主要包括:基础地质研究、野外露头观察描述、岩心观察和描述、镜下薄片观察、物理模拟、各种测井解释、地震解释、各种分析测试统计、地质建模、动态监测和生产动态分析方法等。结合研究实践,对每一种方法的优缺点进行分析。在此基础上,指出了油气田开发中构造地质成因分析存在的8方面主要问题和发展趋势。The genesis analysis of structural geology plays an important role in the oil and gas field development. Based on the research advances in China and abroad, the advantages and disadvantages of the study in this field are compared in detail. There are eight research directions in general. First, the structural geological genesis of fault system is determined through the analysis of structural evolution history and stress field. Second, the genesis of geological structure was analyzed by means of detailed structural interpretation. Third, explore and improve the research methods of structural geological genesis. Fourth, the geological genesis analysis of reservoir is carried out based on comprehensive dynamic and static data. Fifth, structural geological genesis is studied by close combination with sedimentary facies research and diagenesis research. Sixth, application of metallogenic analysis results should be strengthened to provide a basis for the development of oil and gas fields. Seventh, microfracture characterization and modeling. Eighth, microstructural geological genesis analysis. Methods of structural geological genesis analysis in oil and gas field development mainly include: basic geological research, field description of outcrop observation, core observation and description, microscopic thin-section observation, physical simulation, well logging, seismic interpretation, geochemical analysis and testing, geological modeling, dynamic monitoring and dynamic analysis of production. The advantages and disadvantages of each method are analyzed based on case studies. On this basis, it is concluded that there are eight main issues and eight future research directions in the study of the genesis of structural geology in the oil and gas field development.
