地震地层学是七十年代以来新兴起的一门边缘科学,它的诞生适应了油气勘探中晚期寻找地层岩性油气藏的需要,近几年来,国外利用这一方法在研究海相沉积盆地中,不断取得新的成效.对于渤海这类沉积条件较为复杂的陆相沉积盆地,在石油勘探的早期阶段,如何充分利用大量的地震资料信息进行岩性岩相预测,进而提出油气资源评价、指出勘探方向,做到寻找构造油气藏的同时注重非构造油气藏的尝试,无疑是很有意义的.本文结合在渤海含油气区开展地震地层的研究实践,谈些初步认识.
Seismology and stratigraphy is a newly emerging edge science since the seventies. It was born to meet the need of searching for stratigraphic lithologic reservoirs in the late period of oil and gas exploration. In recent years, the use of this method in the study of marine sedimentary basins , And made new achievements.For the continental depositional basin with more complex sedimentary conditions in the Bohai Sea, how to make full use of a large amount of seismic data to make lithologic and lithofacies prediction in the early stages of petroleum exploration, and then put forward the evaluation of oil and gas resources, pointing out It is undoubtedly significant to search for the exploration direction and pay attention to the non-structural reservoirs in the construction of oil and gas reservoirs.Based on the research and practice of seismic strata in the Bohai oil-bearing area, some preliminary understanding is given.
