A well yield metering device

Abstract

The invention provides a well yield metering device comprising a separator, a liquid quantity metering instrument and a gas quantity metering instrument. The side wall near the top of the separator is provided with a liquid coming opening connected with a liquid coming pipe and the bottom of the separator is provided with a liquid discharge port connected with a liquid discharge pipe. The top of the separator is provided with a gas discharge port connected with a gas discharge pipe. The liquid discharge pipe and the gas discharge pipe are jointly connected to a main outlet pipe backward. The liquid quantity metering instrument is arranged on the liquid discharge pipe and the gas quantity metering instrument is arranged on the gas discharge pipe. The separator comprises a separator cavity and a separator umbrella arranged in the middle of the separator cavity for separation. The separator also comprises a secondary separator plate also disposed in the middle of the separator cavity for separation. The secondary separator plate and the separator umbrella are integrally combined to form a cone structure. By using other information means on site, the well yield metering device can greatly improve system efficiency, facilitate the promotion and application of oil field information construction and improve the overall information level of oil field. The well yield metering device has the advantages of reliable performance, low cost, high metering accuracy, convenient installation and maintenance and easy extension and compatibility of systems.

Description

technical field [0001] The invention relates to a metering device, in particular to an oil well output metering device. Background technique [0002] The liquid production rate and gas production rate of an oil well are an indispensable parameter in oilfield development, production and geological analysis. The accuracy of these two parameters directly affects the development of oilfields, geological analysis and adjustment of process schemes. The metering devices widely used in oilfields mainly include traditional vertical separators. The vertical separator requires manual control of metering and cannot achieve continuous metering. It takes too long for low-production wells to measure oil, and the accuracy of gas metering for low-gas rate wells needs to be improved. The metering accuracy is greatly affected by fluctuations or intermittent wells and cannot Realize the matching and compatibility with the informatization and automation systems widely promoted in oilfields.

The vertical separator requires manual control of metering and cannot achieve continuous metering. It takes too long for low-production wells to measure oil, and the accuracy of gas metering for low-gas rate wells needs to be improved. The metering accuracy is greatly affected by fluctuations or intermittent wells and cannot Realize the matching and compatibility with the informatization and automation systems widely promoted in oilfields

Moreover, this measurement method is very labor-intensive for the on-site operators, and most of the time is spent on oil measurement, which affects other work and is inefficient.

At present, no effective automatic placement device has been put into field use
