Improving the technology for the measuring and calculating gas-oil ratio

The article presents the results of the development and field tests of mobile installations for measuring the mass flow rate of crude oil and the volume flow rate of associated petroleum gas, as well as the calculation of the gas factor of oil on their basis. One of the installations for measuring the volume flow of associated gas separated at the reception of the borehole pump and taken from the annulus of the well. The other allows you to select the watered products in the sampling column of the measuring tank and increase the accuracy of measurements of both water and gas. A statistical dependence of the gas separation coefficient at the reception of the electric centrifugal pump is obtained, which allows the installation to be designed in accordance with the amount of gas taken from the annulus of the well. Keywords: gas factor of oil; oil rate; dissolved and free gas; mobile unit; well annulus; gas separation coefficient; pump reception.
