Seismic-geological comprehensive interpretation technology for complex reservoir in sandstones

摘要

In terms of subtle pools, lithologic reservoirs in sandstones are important, and the key points to exploring such reservoirs are reservoir recognition. The recognition and description of sandstone reservoirs mean the tight integration of geology, seismic and well log. According to seismic-geological characteristics of complex sandstone reservoirs in Jiyang depression and main difficulties for the exploration, and based on geological studies, this paper proposes seismic-geological comprehensive interpretation technology for complex reservoir in sandstone using log-constrained inversion, 3D visualization and multi-attribute joint interpretation, etc. The technology has been a complete comprehensive interpretation technology for various reservoirs, which obtained good effects in Yanjia and Luojia areas.
