摘要
层序地层学被引入我国10年来，地质工作者结合我国的具体地质情况，运用层序地层学的理论对古生代海相沉积盆地碳酸盐岩地层进行了研究，探讨了沉积体系域的控矿作用。在一些大比例尺沉积岩区区调工作中，开展了露头层序地质学的研究。在陆相盆地工作中，发现影响陆相地层层序的因素很多，随机性更强。针对这种情况，提出了利用露头、地震和钻井资料综合进行层序地层学的研究，指导油气勘探。此外，利用层序地层学理论，在岩相古地理研究方面也取得了可喜的成果。
Being indroduced into China for 10 years,theory of sequence stratigraphy has been applied by Chinese geologists to the research for marine carbonate formation in Paleozoic sedimentary basins and for ore control in depositional system tract. A research on outcrop sequence stratigraphy has been made in large-scale regional geological surveying in sedimentary petrologic provinces. Stratigaphic sequence in continental basins is affected by numerous factors. To counter these circumstances,we use ortcrop,seismic and drlling data for making a research on sequence stratigraphy in order to guide our oil and gas prospecting. Moreover,the application of sequence stratigraphy to sedimentary facies and paleogeography has made encouraging progress.
