Chemical Kinetics Application of Hydrocarbon Generation of Shuang Yang Stratum in well Chang 27

Abstract:

To determine the hydrocarbon - generating characteristics of Shuangyang Formation in Well Chang 27.We selected dark mudstone in Shuangyang Formation to launch Rock-Eval (open system) thermal simulation. Through thermal simulation data to demarcate a kinetic model,the Shuangyang Stratum mudstone samples reveal the gas intensity is mainly distributed in (210~230) kJ/mol),the average activation energy is 223kJ/mol. The hydrocarbon - generating characteristics of Shuangyang Formation in Well Chang 27 whose hydrocarbon generation stage mainly in the period (37~24) Ma, corresponding the late period of the Yongji Formation deposition to the late period of the Qijia Formation deposition. In Chang 27 Well area,the average generating strength of gas in Shuangyang Formation is (21~37×10⁸) m³·km². The hydrocarbon generation stage of Shuangyang Formation in Chang 27 Well area is mainly in (37~24) Ma, corresponding to the late deposition period of the Yongji Formation and Qijia Formation. Both the shorter periods of hydrocarbon generation and late hydrocarbon generation period made great contributions to accumulation, in which Shuang_1 formation played a bigger role.
