Solid-fluid coupling pressure controlled hydrocarbon generation and expulsion simulating experimental device

Abstract

The invention provides a solid-fluid coupling voltage controlled hydrocarbon generation and expulsion simulating experimental device. In the device, a high pressure kettle is formed by a high pressure kettle body which is connected with a high pressure kettle top cover and a high pressure kettle base respectively, wherein a vertical pressurizing column is axially arranged in the middle of the high pressure kettle; a three-way valve is connected between the high pressure kettle and a high pressure pipeline in a high pressure buffer which is provided with a piston; the high pressure buffer is connected with a fluid pressure control pump pipeline; a two-way valve with a switch is connected to a connecting pipeline of the three-way valve and a gas collecting device; a stainless steel piston is arranged in the high pressure buffer, and distilled water for controlling pressure and stratum simulated fluid are filled in cavities at two sides of the stainless steel piston; an upper connecting hole and a lower connecting hole on the high pressure reacting kettle are communicated through the high pressure pipeline; and the high pressure pipeline is communicated with the three-way valve.

Description

Technical field: [0001] The invention relates to experimental equipment, and more particularly relates to a solid-fluid coupled pressure-controlled hydrocarbon generation and expulsion simulation experiment device applied to hydrocarbon source rocks. Background technique: [0002] The hydrocarbon generation and expulsion simulation experiment is to reproduce the underground hydrocarbon generation and expulsion process under indoor conditions. Through the simulation experiment, the evolution law of hydrocarbon generation and expulsion of source rocks can be studied, and the quantitative parameters of hydrocarbon generation and expulsion can be obtained. Only by simulating the underground conditions as much as possible can the experimental results reflect the objective situation more accurately. The influencing factors of hydrocarbon generation and expulsion under geological conditions are complex, including temperature, static rock pressure, fluid pressure, fluid composition,...

Problems solved by technology

If this condition cannot be met, it is difficult to effectively simulate the effect of subsurface overpressure fluid on hydrocarbon generation and expulsion, and it is also impossible to simulate the influence of fluid chemical properties on hydrocarbon generation.
