Abstract:
Based on the principle of chromatographic fingerprinting technology, P 2 l 2 2-1 , P 2 l 2 2-2 and P 2 l 2 2-3 single layer shale oil chromatographic fingerprint libraries of upper sweet spot in Jimsar Sag were established by laboratory matching experiment. The partial least squares method was used to realize the capacity contribution calculation and dynamic monitoring of the single layer in two layer and three layer shale oil of the dessert in Jimsar. The result shows, upper sweet shale oil of Lucaogou Formation in Jimsar Sag are mainly supplied by P 2 l 2 2-1 layer and P 2 l 2 2-2 layer. Oil mainly supplied by P 2 l 2 2-1 layer in the wells of JI 37 and JI 171, which are combined with P 2 l 2 2-1 and P 2 l 2 2-2 . Oil mainly supplied by P 2 l 2 2-2 layer in the wells of JI 25 and JI 173, which are combined with P 2 l 2 2-2 and P 2 l 2 2-3 . Oil mainly supplied by P 2 l 2 2-1 layer in the wells of JI 174 and JI 176, which are combined with P 2 l 2 2-1 , P 2 l 2 2-2 and P 2 l 2 2-3 , followed by P 2 l 2 2-2 . In addition, it is found that with the progress of oil exploitation, the contribution rate of P 2 l 2 2-1 in JI 174 well and JI 176 well is gradually reduced, and P 2 l 2 2-2 becomes the main oil supply layer. The physical properties and oil saturation of the corresponding reservoirs in each well were analyzed. And the results proved the accuracy and rationality of the calculation results.
