【Abstract】 It is known that the multi-layered gas reservoirs exist in Penglaizhen member of Luodai gas field, after years exploration and production. In this paper, the author finds out the seismic and geological characters of Penglaizhen member, which are the strong amplitude and low frequency and low velocity,by using gas reservoir model studying and fine match of seismic data with geology data. The 3D distribution and thickness variation of main gas reservoirs are well described by adopting 3D perspective interpretation on the seismic data and well log constrained seismic inversion data. Combining geology analysis and seismic technique together, the favourable sedimentary facies zone is predicted. The sedimentary facies are meandering stream and anastomosed stream. Many research achievements and good geological result are achieved.更多还原
