The PVT analyzer is an analytical device used to determine the high-pressure physical properties of formation fluids (including heavy oil, black oil, volatile oil, condensate gas, natural gas, CO2, formation water, etc.), and is also an important equipment for improving oilfield recovery experiments. The main measurement includes the relationship between the volume and pressure of the sample under formation temperature conditions, saturation pressure, compression coefficient, formation crude oil viscosity, formation crude oil density, original dissolved gas oil ratio and volume coefficient, as well as the viscosity of crude oil under various gas containing (CO2, N2, H2O, etc.) concentration conditions. It can simulate multi-stage degassing and multi-stage viscosity measurement of oil and gas separation due to pressure reduction in formation oil production process. Widely used in the analysis of formation crude oil components, constant mass expansion experiments, single degassing experiments, multiple degassing experiments, separation experiments, and viscosity measurement.
