运用成藏动力学和成藏压力箱观点,阐明了白庙构造4期构造活动对深层油气成藏的影响和控制作用。分析了构造活动和断层发育通过对沉积扇体、储集层的控制,影响到该区岩性圈闭形成和有利储层分布,从而控制油气成藏和油气分布。研究表明,构造活动和断层发育在白庙构造4次油气充注过程中直接地影响和控制油气运移、聚集、保存、破坏,同一断层在不同的时期对油气成藏分别有不同的作用;认为由于构造活动和断层发育导致该区地层不均衡压实和同沉积作用存在,而在断层发育区地层压力得到释放,它们是现今地层压力分布和流体压力封存箱形成的主要原因,也是白庙地区油气成藏的主要动力。
Using the viewpoints of accumulation kinetics and reservoir pressure tank, the influence and control action of the 4th member of the Baimiao tectonic activity on deep hydrocarbon accumulation are clarified. It is analyzed that the tectonic activities and fault development control the formation of oil and gas reservoirs and the distribution of oil and gas through the control of sedimentary fan bodies and reservoirs and the formation of lithologic traps and the distribution of favorable reservoirs in this area. The results show that tectonic activities and fault development directly affect and control hydrocarbon migration, accumulation, preservation and destruction during the formation of the four reservoirs in the Baimiao structure. The same fault has different effects on hydrocarbon accumulation in different periods. It is thought that due to the tectonic activity and fault development, the strata in this area are unevenly compacted and have the same sedimentation effect. However, the formation pressure in the fault zone is released. These are the main reasons for the formation pressure distribution and fluid pressure accumulation tank formation. Regional oil and gas accumulation of the main driving force.
