Abstract

Lower Devonian of the unconformity surface under the transgressive system tract, can be divided into 2 grade four parasequence. The parasequence boundary occurred in seismic lithology conversion, there exist obvious reflection feature, which marked the alignment sequence interface following seismic waveform analysis, barrier dam reflection characteristics as lenticular strong reflection characteristics, through a variety of cluster analysis of seismic attributes can be fast delineation of barrier dam development zone, three-dimensional perspective technology to identify single sand distribution range, in the 438B block of Lower Devonian using seismic data to study barrier sand bar distribution characteristics is the key to the accurate identification of sequence interface. Through the practical application of this technology effectively guide the exploration and production, and achieved good effect result for lithological reservoir exploration.
