The application of geophysical technology in the middle and late development of Bohai C oilfield
This study is based on the geological situation of high water content in the later stage of oilfield development.Targeted methods such as matched filtering seismic velocity spectrum,analysis of fluvial reservoir configuration,and hydrocarbon detection based on rock physics theory were used to solve the production pain points of low amplitude structural characterization,description of residual oil in fluvial sand bodies,and prediction of oil and gas boundaries in reservoir sand bodies in Bohai C Oilfield.An additional geological reserve of 111.5 million cubic meters was added,Realized the geological requirements of rolling edge expansion and fine potential tapping in the oilfield.
