Abstract:

A series of works was carried out to modernize the domestic automated software-measuring complex, designed to find the function of relative phase permeabilities in two-phase oil-water filtration, in order to equip it with the additional ability to filter gas together with two fluids.

The creation of a software-measuring complex that allows to study three-phase filtration is an urgent task of a complex analysis of a field. Complexes produced by the industry with the possibility of three-phase filtration have a high cost. In this regard, there is a need to create a structurally simple and low-cost method for gas filtration, which is the subject of this work.

In order to carry out gas filtration in the software-measuring complex, an intermediate stainless steel tank is installed in the area intended for creating reservoir pressure. Thus, part of the gas from the cylinder goes to the back pressure regulator, thereby forming reservoir pressure, and part is diverted to an intermediate reservoir. A pressure regulator is installed to regulate the gas flow. In this variant, gas is supplied directly to the end of the core holder in parallel with the water line, so fluids and gas are directly mixed in the body of the core holder.

Methodical experiments on filtration of a gas-liquid mixture with subsequent determination of the volumetric flow rate of gas using the equation of state of a real gas were carried out. An analysis was made of the possibility of using this modernization of the installation for further study of three-phase or two-phase filtration.
