The Comparative Analysis of the Hydrocarbon Generation KineticsCharacteristics of Marine Carbonate Rocks and Marine Mudstone
Use Santanghu limestone and Xiamaling shale respectively represent marine carbonate rocks and marine mudstone, doing research on their hydrocarbon-generating kinetics characteristics in opening system, the results show that the activation energy of oil and gas generation of marine carbonate rocks (Santanghu limestone) have a smaller distribution range, the activation energy of oil and gas generation of the marine mudstone (Xiamaling shale) have a larger distribution range. And applied the simulation results in well Mandong 1 in Tarim Basin, the comparisons show that; oil generation threshold depth of marine carbonate rocks (2 000 m) is 1 000 m shallower than the oil generation threshold depth of marine mudstone, but before S 000 m depth, the oil generation rate of the marine mudstone is slower. The gas generation threshold depth marine carbonate rocks are deeper. The hydrocarbon generation peak of marine carbonate rocks and marine mudstone are both at 6 000 m, but the gas generation rate of the marine carbonate rocks is faster.
