Application of sand body description technology in reserves evaluation of fluvial facies reservoir in Neogene Bohai sea
-
Abstract
The role of sand body description technology of fluvial facies reservoir exploration and development in Neogene Bohai sea becomes more obvious,which mainly reflects in:reasonably determining fluvial facies oilfield exploration well placement and acquire coring data,improving the success rate of drilling and reservoir cores for accuracy;quantitative description of drilled oil sands body;accurately determination of oil-bearing area and effective thickness parameters;quantitative reserves potential and the overall grasp of the oilfield reserves.Through comparison analysis of sand body description technology application effect before and after double calculation of 6 fluvial facies oilfields,the technologyis found to provide area and effective thickness of higher accuracy.Besides that,the technology is of remarkable effect on undrilled potential oil sand body,and on the reasonable grasp of the reserves scale.
