Abstract
Disclosed is an experimental device and method for solubility determination of methane in oil-based drilling fluid, comprising a pressure-resistant gas chamber and an equilibrium still both arranged in a constant-temperature oil bath heating oven, a gas booster pump, and a vacuum system used for vacuuming the pressure-resistant gas chamber and the equilibrium still, and a data acquisition device for collecting temperature and pressure signals; the gas booster pump is connected to drive air source inlet, a gas check valve is arranged on the pipe between the pressure-resistant gas chamber and the gas booster pump that is also connected with a high-pressure gas cylinder, the equilibrium still is divided into a dissolution equilibrium chamber at the top and a hydraulic oil chamber at the bottom by a high-pressure dynamic seal structure, the dissolution equilibrium chamber is connected to a liquid inlet funnel through the fourth globe valve.
