【摘要】：束鹿凹陷位于冀中坳陷南部,为东断西超的单断箕状凹陷。雷家庄地区位于束鹿凹陷的南部,研究区生、储、盖搭配合理,油气资源丰富,近些年在该地区勘探取得了一些新的突破,但由于断层分布密度、储层条件及油水分布复杂,油气成藏特征的研究不够深入,该地区的下步勘探方向仍不明朗。本文系统的分析雷家庄地区的层序、沉积、构造特征等各种成藏条件,剖析已发现油气藏成藏,认清雷家庄地区的油气成藏特征、总结油气成藏主控因素,提出下步勘探的有利区带。通过基础石油地质研究认为研究区具有良好的烃源条件、有利的储层分布、稳定的盖层条件、良好的运移条件和有利的圈闭条件。选取雷家庄地区不同构造带上的典型油气藏,对油气成藏条件、成藏特征综合分析认为雷家庄地区有构造、地层、岩性和复合型四类油气藏;分析输导体系要素及总结油气成藏特征的研究,研究区的输导体系组合模式主要有两种类型:断层-渗透性储层型输导体系和不整合面-渗透性储层型输导体系。在此基础上,分析研究区的油气藏在纵向上和平面上的分布特征,通过综合分析阐明了雷家庄地区油气成藏的主控因素:烃源岩的展布控制成藏分布;圈闭的有效性控制油气成藏;断层的封堵条件是油气聚集成藏的关键;不整合面及有效砂体连通性控制斜坡带油气分布与富集。
[Abstract]:Shoulu depression is located in the southern part of Jizhong depression, which is a single-faulted dustpan sag with east fault and west superimposed. The Leijiazhuang area is located in the south of Shulu sag. The study area is characterized by its source, storage, reasonable cap collocation and abundant oil and gas resources. In recent years, some new breakthroughs have been made in the exploration in this area, but due to the complexity of fault distribution density, reservoir conditions and oil-water distribution, the study on the characteristics of oil and gas reservoir formation is not deep enough. The next exploration direction in this area is still unclear. This paper systematically analyzes the sequence, sedimentation, structural characteristics and other reservoir forming conditions of Lejiazhuang area, analyzes the oil and gas reservoir forming conditions, and recognizes the oil and gas accumulation characteristics in the Leijiazhuang area. The main controlling factors of oil and gas accumulation are summarized, and the favorable zones for the next exploration are put forward. Through the basic petroleum geology research, it is considered that the study area has good hydrocarbon source conditions, favorable reservoir distribution and stable caprock conditions. Good migration conditions and favorable trap conditions. Typical oil and gas reservoirs in different structural zones in Lejiazhuang area are selected. Comprehensive analysis of oil and gas accumulation conditions and reservoir forming characteristics shows that there are structures and strata in Lejiazhuang area. Lithologic and composite oil and gas reservoirs; analysis of the elements of the transportation system and summary of the characteristics of oil and gas accumulation, There are two main types of transport system combination models in the study area: fault-permeable reservoir transport system and unconformity-permeable reservoir transport system. The distribution characteristics of oil and gas reservoirs in the study area are analyzed. The main controlling factors of oil and gas accumulation in Leijiazhuang area are expounded through comprehensive analysis: the distribution of hydrocarbon source rocks, the effectiveness of traps, the control of oil and gas accumulation, the distribution of oil and gas reservoirs in Lejiazhuang area, the distribution of oil and gas reservoirs in Luijiazhuang area. The fault plugging condition is the key to the accumulation of oil and gas and the unconformity surface and effective sand body connectivity control the distribution and enrichment of oil and gas in the slope zone.
