HOW TO PKOMOTE THE DEVELOPMENT OF SEQUENCE STRATIGRAPHY RAPIDLY IN CHINA

Xu Huaida(China University of Geosciences,Beijing,100083)  
Sequence stratigraphy has been developed just like a wildfire at large in theworld since it came out in 1987,and it is very interesting especially to the petroleum geo-logic circle. It walks with difficuIty,however,in China and is progressing slowly, Thereasons of this situation are discussed in this paper:(1) It is not understood that the seis-mic reflections are basically geological synchronous surfaces,(2) The concepts of sequencestratigraphy result from studies of marine sediments deposited on passive margins of thecontinent and they are considered to be unacceptable to nonmarine sediments. (3)The fre-quencies and resolutions of conventional seismic data are too low and not available for se-quence stratigraphic studies,(4)Sequence stratigraphy is one of pure sciences,it is usual-ly divorced from realities of oil/gas exploration,and it may disrupt the order of geologicalworking if we accept the concepts of sequence stratigraphy in exploration work. The prob-lems mentioned above are discussed in this paper positively.
