The Study Of Paleogene Reservoir Based On Seismic Inversion In Chengdao Eastern Slope

Reservoir is the direct target of oil exploration and development,the core of oil pool.The distribution and nature of the reservoir are closely related to the oil and gas reserves.Therefore,it is of great significance to develop a series of geological and geophysical solutions that can effectively identify the favorable reservoir and analyze the physical condition of the reservoir.Based on the geological knowledge,well logging data,seismic data and so on,this paper has obtained the underground reservoir parameter distribution through the inversion method,and has carried on the favorable target forecast.For the Paleogene of Chengdao eastern slope has low resolution seismic data,deeply buried target layer,small velocity difference between sandstone and mudstone,based on the previous research results,we analyze the original seismic data and physical condition of the reservoir of the two target sets of Paleogene.We use post stack wavelet frequency division processing technology to broaden the frequency band of seismic data and improve the resolution;and then,use the seismic phase controlled nonlinear stochastic inversion to reservoir prediction technology,to study the reservoir distribution characteristics of the main target layer of the well area.Finally,we preferred exploration targets,and lay a good foundation for further development of Chengdao eastern slope.
