Device for measuring gas factor

The utility model relates to the oil and gas industry and can be used to measure the gas factor of oil with high gas content and to determine the proportion of gas entering oil wells from the gas cap during the development of the reservoir.

A device for separating well products, consisting of a gas separator with gas treatment sections (1), is known.

The known device allows you to separate the gas from the liquid (oil) and purify the gas from mechanical particles, however, the accuracy of determining the gas factor is low.

The closest to the utility model in technical essence is a device for measuring the gas factor, including a fitting, a pipeline and a gas separator (2).

The known device allows you to more accurately measure the gas factor of oil, however, the device does not allow you to accurately determine the gas factor of oil with high gas content.

The utility model solves the problem of increasing the accuracy of determining the gas factor of oil with high gas content.

The problem is solved by that. that the device for measuring the gas factor, including the gas separator and pipelines, according to the utility model, contains an additional gas separator and shut-off equipment, while the first gas separator

Utility Model

In oil fields with a large gas phase and with a gas cap, the problem arises of accurately determining the amount of gas entering the wells from the gas cap. In this case, the development parameters of the oil reservoir are determined, the need to create barriers for separating the gas cap and the oil zone, the equivalence of gas withdrawals from the gas cap and oil from the oil zone, etc. However, the gas factor, and therefore the amount of gas cap gas in wells, cannot be measured with sufficient accuracy by existing devices. The utility model solves the problem of increasing the accuracy of measurements of the gas factor of oil with high gas content. The problem is solved by the device for measuring the gas factor shown in FIG.

The device includes a vertical gas separator 1 connected by a gas pipeline 2, equipped with a throttle measuring washer 3, a check valve 4 and a valve 5, with a gas manifold 6. A vertical gas separator 1 is connected to a horizontal gas separator 7 by an oil pipe 8, equipped with a valve 9 and a check valve 10. Horizontal the gas separator 7 is connected by a gas gas duct 11 provided with a throttle measuring washer 12 and a check valve 13, with a gas collector 6 and. as well as an oil pipeline 14, equipped with a turbine meter 15 and a discharge valve, valve 16, with an oil manifold 17

the oil pipe 8 through the open valve 9 and the check valve 10 to the horizontal gas separator 7 where the pre-pre-heater is separated from the gas and passes through the oil pipe 14 through the turbine meter 15 and the relief pneumatic valve 1S to the oil manifold 17. The separated gas and oil vapors after the vertical gas separator 1 pass through the gas pipeline 2 through the throttle measuring washer 3, the check valve 4 and the open valve 5 to the gas manifold 6. The separated gas after the horizontal gas separator 7 flows through the gas pipeline 11 through the throttle th measuring washer 12 and check valve 13 into the gas mixing manifold 6 with a gas after the vertical gas separator 1. By measuring throttle washers 3 and 12 define :: ra gas passages that summarize By turbine meter 15 determines the flow rate of oil. Knowing the costs of oil and gas determine the total amount of gas. Knowing the gas factor of oil, the amount of gaaa entering the production wells when calculating the deposit is calculated as the difference between the total amount of gas and the amount of gas from the gas factor.

Check valves, gate valves, relief pneumatic valves are elements of shut-off equipment and are used to connect, separate pipelines and to prevent the backflow of oil and gas.

Specific Execution Example

A device for measuring a gas fayetor (Fig.) Includes an SC-400 cyclone separator 1 as a vertical gas separator, an AM 40 separator as a horizontal gas separator 7, and a 1G turbine meter

TOR counter. The electrical part of the device is provided by integrated gas meters. Gas meter ZM. The device is installed on a wellbore and connected to the Sputnik automatic gas meter. The device serves the production wells of the Luginetsk oil and gas condensate field. As a result of measurements, it was found that the total amount of gas entering through the oil production well is 220 with a gas factor of 200 mt, which indicates the flow of 20 M gas from the gas cap of the oil reservoir.

The use of a useable modoli will increase the accuracy of determining the gas phase of oil and the amount of gas. coming into production wells from the cap at the development of the oil reservoir
