潍北拉分盆地形成演化及其对成油气条件的控制
Tectonic evolution and its controlling on petroleum generation in Weibei Basin
【摘要】 潍北盆地是发育于郯庐断裂带内的中、新生代盆地。在大量地震资料解释与构造成图的基础上,通过构造解析和沉积分析等基础工作.证实潍北盆地是一个典型的走滑伸展盆地,盆地演化经历了走滑挤压阶段(白垩纪末)、走滑伸展阶段(孔店组沉积期)、坳陷与走滑挤压阶段(新近纪)等3个阶段。构造样式包括花状构造、伸展构造以及走滑挤压产生的压扭性断鼻等。控盆断裂的右行走滑导致了孔店组一段、二段砂体向南迁移。潍北盆地发育良好的生储盖组合以及多类型圈闭,具有良好的勘探前景。图7参6
【Abstract】 Weibei Basin is a Mesozoic-Cenozoic basin developed in the Tanlu fault zone. Based on interpretation of large amount of seismic data and structure mapping, the basin is proved to be a typical slip-extensional basin according to structure and sedimentation analysis. The basin experienced 3 stages of evolution, slip-compressing movement in the end of Cretaceous, slip-extensional movement during the deposition of Kongdian Formation and depression and slip-compressing movement in Neogene. Structure styles include flower structure, extensional structure and fault nose caused by slip-compression. Favorable source-reservoir-caprock association and multi-type traps were developed in Weibei Basin and that should be a favorable area for petroleum play.
