用叠后地震正演模拟方法精确解释东河砂岩尖灭点 - The result shows that the hydrocarbon resources are abundant , physical properties of the reservoirs are mainly of mid - porosity and mid - low permeability reservoirs , its trap types are mainly of overlying pinchout lithological traps and structural or lithological - structural traps , accumulation conditions are good
结果表明，研究区油气资源丰富，储层物性主要为中孔中低渗储层，圈闭类型主要为砂岩上倾尖灭的岩性圈闭和构造或岩性构造圈闭，成藏条件较好。 - 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
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。
