英文摘要 | This study attempted to more accurately predict the production performance and recoverable reserves in the late development stage, by formulating a new expression of Kro/Krw versus Sw by regression for the whole relative permeability curve. Further, on the basis of the Buckley-Leverett's frontal-drive equation and the Welge's average water saturation equation, two kinds of new water flooding curve were derived from the new expression of Kro/Krw, which are more applicable for predicting the final recoverable reserve. The laboratory tests conducted in the study show that the new cubic water flooding curve R-fw follows the experimental curve, and the the final oil recovery calculated in the tests are the amount predicted by the new water flooding curve. An oilfield case study was also carried out, which indicates that the economically recoverable reserve at the water cut of 98% is 2.789 ?? 104 m3 through the new approach, which has the smallest percentage of error 0.12%.; EI; 0; 5; 817-830; 32 |
