Abstract

WZA-7N structure is located in the intersection area of multiple provenances, which is generally the prospective zone of development of lithological reservoir. Due to the limitation of seismic resolution, conventional seismic data cannot accurately describe lithological boundaries, not only increase the exploration risk, but also affect the reliability of reserve calculation.in face of this exploration problem, according to the difference of every seismic trace in one prestack gather, resolution in every prestack gather in aspect of seismic resolution imaging quality and geological characteristics reaction, combined with the seismic wave group characteristics of well synthetic seismogram and VSP corridor stacking traces, author designed a set of technical process for advantage seismic tace stacking, which can effectively improve seismic resolution and interpreted lithological boundaries again. The subsequent drilling confirmed the correctness of the new lithological interpretation scheme. Practice further shows that the advantage tace stacking technique can effectively improve seismic resolution and interpretation accuracy of lithological boundary, which is a practical technique suitable for fine exploration of lithological reservoirs in weizhouA-7N structure.

Key words： pre-stack gather VSP corridor stack traces advantage trace stack seismic resolution lithological boundary
