Abstract

The application provides a method and apparatus to simulate an unconventional oil-gas forming process. The method comprises: increasing the temperature of a hydrocarbon source rock sample, placed in ageologic model cylinder of a simulating device, gradually to a target temperature via N stages, and increasing the pressure, which the top of the hydrocarbon source rock sample bears, gradually fromthe normal pressure to the target pressure via N stages, wherein in the different temperature rise and pressure rise stages, different hydrocarbon source rock samples are placed in the geologic modelcylinder and have the same properties; acquiring hydrocarbon forming parameters, which are used for evaluating the hydrocarbon forming process, corresponding to each temperature rise and pressure risestage. The method and apparatus provided herein provide better accuracy for the simulation results of the unconventional oil-gas forming process.

Description

technical field [0001] The embodiments of the present application relate to unconventional oil and gas technology, and in particular to a method and equipment for simulating the formation process of unconventional oil and gas. Background technique [0002] Unconventional oil and gas such as shale oil and gas, tight oil and gas, and coalbed methane have become an important component of oil and gas resources and will gradually become the main body of oil and gas resources. However, due to the special geological characteristics and accumulation conditions of unconventional oil and gas, it has a different accumulation mechanism and distribution law from conventional oil and gas. At present, the research on the accumulation mechanism and enrichment mechanism of unconventional oil and gas is still very weak, especially on the time-space matching between hydrocarbon generation and expulsion charging and reservoir densification, non-buoyancy driving efficiency, and fluid flow mechan...
