Current status and progress of exploration technology for lithologic-stratigraphic reservoirs in China

Lithologic-stratigraphic traps (reservoirs) in China are characterized by complex boundary condition, irregular shapes, subtle occurrence, complicated reservoir forming condition and various migration and accumulation mechanisms. At present, China has formed basic research methods including sequence stratigraphic analysis method and three-phase interpretation technology for lithologic reservoirs exploration, and multi-parameter comprehensive evaluation methods for seismic data, such as pre-stack seismic inversion technology, seismic attribute analytic technique, fluid potential analytic technique and oil and gas detection technology. It is proposed that we should strengthen fundamental geologic research and continuouslyimprove the standard and criterion, attach importance to the organic integration of geological and geophysical exploration studies, timely organize key technology research and carry out technical storage for lithologic reservoirs exploration.
