Problems solved by technology
The hydrocarbon expulsion rate calculated by this method is usually relatively large, and it is difficult to apply it to actual geological work
In order to more realistically simulate the process of oil and gas generation and discharge under geological conditions, in addition to considering various geological factors such as: temperature, time, overlying static rock pressure, formation fluid pressure, confining pressure, pore space, pore fluid properties and rock In addition to factors such as mineral composition, the hydrocarbon generati

The invention provides a simulation experiment device and a simulation experiment method for hot-press hydrocarbon generation and discharge based on the basin evolution history, and belongs to the technical field of petroleum and gas geochemical experiment study. The experiment device comprises a hydrocarbon generation system and a discharged hydrocarbon collecting system which are connected through a multi-channel combined valve (139). The method comprises the steps of dividing different stages of basin evolution according to the construction evolution history of an actual geologic basin, automatically regulating the communicated state of the hydrocarbon generation system and a hydrocarbon discharge device, and simulating the hydrocarbon generation and discharge processes under a basin dynamic evolution condition. According to the invention, the hydrocarbon source rock hydrocarbon generation and discharge simulation experiment approximate to the construction evolution history of the basin containing petroleum and gas is achieved by combining with the construction evolution history of the basin and considering influences of paleo-fluid pressure fields of hydrocarbon source rock and reservoir rock to the generation and discharge of petroleum and gas, which are caused by basin evolution.
Description
technical field [0001] The invention belongs to the technical field of oil and natural gas geochemical experiment research, and in particular relates to a thermal pressure hydrocarbon generation and expulsion simulation experiment device and method based on the evolution history of a basin. Background technique [0002] Since the 1970s, the simulation experiment method of hydrocarbon generation and expulsion under thermal pressure of source rocks established based on the theory of late thermal degradation of kerogen and the time-temperature compensation principle of organic matter thermal evolution proposed by B.P Tissot et al. It is one of the most effective methods for the formation mechanism of oil and gas, the evolution process of sedimentary organic matter, and the amount of hydrocarbon generation of source rocks. For this reason, many scholars at home and abroad have developed various source rock hot-press hydrocarbon generation simulation experimental devices, which c...
