【摘要】 通过阐述马厂地区的地震剖面资料,提出了该区断块潜山的四种构造样式:断阶状地垒断块潜山、不对称式半地垒断块潜山、倾斜不对称半地垒状断块潜山和高幅度不对称半地垒状断块潜山。在此基础上总结出断块潜山顶面的总体特点为:南高北低,南宽北窄,南缓北陡。并在综合地层和生产资料的基础上,讨论了马厂地区潜山的成藏特点。潜山储层具备风化侵蚀作用形成广泛发育的裂缝、后期的构造翘倾运动造成的地势差以及其切割断层发挥的油气运移通道作用和封堵作用,得出潜山储层是油气勘探优势储层的结论。更多还原

【Abstract】 According to interpreting seismic cross sections,four structural patterns of buried hill are put forward,they are step-like horst buried hill,asymmetry half-horst buried hill,tilt asymmetry half-horst buried hill and high range asymmetry half-horst buried hill.Thus the top face topography of block buried hill can be summarized as:the southern part is high,wide and gentle,while the northern part is low,narrow and steep.The oil accumulation of buried hills in Machang reign are also discussed integrated by strata and production data.Because abundant cracks formed by weathering and erosion,terrain height formed by tectonic tilting and the functions of oil-gas migration channel and sealing which the cutting faults play,buried hill reservoir can be recognized as the advantaged reservoir for petroleum exploration.更多还原
