Seismic identification and evaluation of Ordovician carbonate reservoir in Shunnan area
摘要
Abstract
The carbonate reservoir of Shunnan area is characteristized by multiply types,deep burial depth,large reservoir scales,complex space distribution and development degree,few drilling wells and relatively lower SNR of seismic data and difficult for the reservoir identification and evaluation and evaluate.Aimed at the research difficulties,firstly,based on the drilling,logging,seismic and geology data,the petrophysical parameters are analyzed;then,the seismic-geologic model is built which is coinciding with the actual underground situation,and the seismic wavefield features of carbonate reservoir is studied with forward modeling.On the basis,identification patterns of different reservoir types are established.Secondly,we carry out the analysis and experiments on seismic sensitive parameters to different types of reservoir,the prediction methods for different scales of reservoir and the detection methods for micro-faults,fractures are determined.Finally,we conduct hydrocarbon reservoir evaluation with comprehensive utilization of reservoir identification,fractures detection results and hydrocarbon prediction results,and favorable area and exploration targets are selected optimally.Carbonate reservoir recognition and evaluation are proved available in Shunnan area.关键词
