油藏地球物理技术在大庆长垣LS油田的应用
Application of the Reservoir Geophysics Technology to LS Oilfield of Daqing Changyuan
摘要
Abstract
According to the problem of using reservoir geophysical techniques in potential tapping of residual oil becoming hard in Daqing Changyuan,this article systematically expounds well-to-seismic integration structure research and reservoir prediction.Well-to-seismic integration technique makes micro structure interpretation successful in the practice.(1) Hierarchical structural interpretation is carried out,and structural interpretation of small-scale geologic body is established; (2) On low grade faults identification and combination,well log data are used to guide and to verify seismic faults interpretation,combined with the techniques concluding coherent body inclination positioning,3 D visualization,etc; (3) On micro-amplitude structure,well point hierarchical data grid mapping are adopted,assisted by hand recognition,trend surface analysis,coherence cube,to implement the structure one by one.The practice of reservoir application proves that the popularity of using seismic attribute to predict reservoir is very limited,but in predicting ' bit balling sand' sand body,it is successful.The accuracy of seismic reconstruction inversion technique in reservoir prediction proves to be very high.It not only reflects sand bodies contact relationship well,but also predicts sand body horizontal boundary.By the method of ‘ well determine facies,slice assemble shape',using the characteristics of well log shape difference and height difference etc,assisted by inversion slice in river course vertical evolution research,finally multiperiod river classification is achieved.关键词
