Carbon/Oxygen Spectral logging was run 130 wells in Sartu Oilfield,Daqing,during 2002 to 2004.Applications of C/O log result in good effect in identifying flood layer,direct perforation-selecting in new well or perforation-adding in old well,as well as block off,etc,in middle and high porosity and permeability region,and provide bases for infill adjustment and syntheses measure.
C/O log data from 18 tertiary infilling & adjusting wells are processed, the interpreted results of which show that the C/O log data are an important proof judging the thin reservoir's remaining oil saturation, infilling & adjusting plan and reperforating in the later stage of oilfield development, and also have more advantage over other production logging techniques after casing running.
In the light of geological features of westblack, Nanliu zone in Daqing Oilfield, the C/O log data processing and interpretation model is improved, based on which established are new math models for calculation of shale content, median grain diameter, porosity, bound water saturation and permeability, etc. C/O log data from 18 tertiary infilling & adjusting wells are processed, the interpreted results of which show that the C/O log data are an important proof judging the thin reservoir's remaining oil satur...
