东濮凹陷濮城构造形成演化及与油气关系的开题报告【摘要】东濮凹陷位于中国山东省东南部，是中国主要的油气勘探开发区之一。其中，濮城构造是该凹陷区域内的一个重要构造单元，其构造形成及发育演化与油气成藏有着密切联系。本文以东濮凹陷濮城构造为研究对象，探讨其构造形成演化历史及与油气勘探开发的关系，为后续油气勘探开发提供科学依据。本文首先介绍了东濮凹陷概述及研究现状，然后对濮城构造的地质特征进行了分析，包括构造类型、构造分布、构造特征等。接着，对濮城构造形成演化历史进行了探讨，分别从古构造基础、前古生代、中生代和新生代四个时期进行了分析，强调了构造演化中断的作用。最后，通过分析濮城构造与油气勘探开发的关系，指出了不同阶段构造发育对油气成藏的影响，同时提出了有关油气地质问题的研究方向和对策建议，包括进一步深入认识油气来源、运移、成藏机制，完善勘探技术和加强勘探投入等方面。【关键词】东濮凹陷；濮城构造；构造形成；油气勘探开发；成藏机制【Abstract】TheDongpuDepressionislocatedinthesoutheastofShandongProvince,China,andisoneofthemostimportantoilandgasexplorationanddevelopmentareasinChina.ThePuchengstructureisanimportantstructuralunitinthisdepression,anditsstructuralformationanddevelopmenthistoryarecloselyrelatedtotheaccumulationofoilandgas.ThispapertakesthePuchengstructureintheDongpuDepressionastheresearchobject,exploresitsstructuralformationandevolutionhistory,anditsrelationshipwithoilandgasexplorationanddevelopment,providingascientificbasisforsubsequentoilandgasexplorationanddevelopment.Firstly,thispaperintroducestheoverviewandresearchstatusoftheDongpuDepression,andthenanalyzesthegeologicalcharacteristicsofthePuchengstructure,includingthestructuraltype,distribution,andcharacteristics.Then,theformationandevolutionhistoryofthePuchengstructureisdiscussed,andanalyzedfromfourtimeperiodsofancientstructurefoundation,earlyPaleozoic,Mesozoic,andCenozoic,emphasizingtheroleofstructuralevolutioninterruption.Finally,throughtheanalysisoftherelationshipbetweenthePuchengstructureandoilandgasexplorationanddevelopment,thispaperpointsouttheimpactofthedevelopmentofdifferentstagesofthestructureonoilandgasaccumulation,andproposesresearchdirectionsandcountermeasuresforoilandgasgeologicalissues,includingfurtherunderstandingofoilandgassources,migration,anddepositionmechanisms,improvingexplorationtechnologyandenhancingexplorationinvestmentandotheraspects.【Keywords】DongpuDepression;Puchengstructure;structuralformation;oilandgasexplorationanddevelopment;depositionmechanism
