摘　　要：对陆家堡凹陷油藏形成的石油地质条件、已知油藏类型及分布的分析认为:生油区、生储配置关系、储集物性、沉积相带和二级构造带控制了油藏的形成和展布,其中围绕生油洼陷的油藏含油最丰富;夹持或嵌入主要生油层中,储层发育、储集物性又相对较好的九佛堂组上段是主要含油层段;近岸水下扇的扇中和扇三角洲前缘是最有利的相带:凹陷的陡坡带以构造油藏为主,斜坡带以构造-岩性及储层上倾尖灭油藏为主,深陷带主要为透镜状岩性油藏。该结果为陆家堡凹陷下一步的勘探提供了一定的依据。Analysis of petroleum geology, reservoir types and distribution in Lujiapu Depression indicates that:the forming and distribution of reservoirs had been controlled by source area, source-reservoir relationship, petrophysical characteristics, sedimentary facies and secondary structure, and oil is most abundant in reservoirs around hydrocarbon kitchen; the upper member of Jiufutang formation which was entrained or embedded in the main oil source layer has well developed reservoir and good petrophysical property and is the principle oil-bearing interval; the mid-fan and fan delta front of nearshore submarine fan is the most favorite facies; the steep slope of the depression mainly consists of structural reservoirs, the slope belt mainly consists of structural-lithologic and updip pinchout reservoirs, the depressed belt mainly consists of lenticular lithologic reservoirs. This result provides basis for further exploration in Lujiapu Depression.
