Problems solved by technology

The biggest disadvantage of this metering principle is that it takes a long time to measure to achieve a certain metering accuracy. When many oil wells share a metering device, the number of oil wells that can be metered is limited. In addition, there is a certain delay when crude oil flows into the dump The acceleration will also affect the measurement accuracy

Abstract

The invention discloses a novel tipping bucket type crude oil metering system. The novel tipping bucket type crude oil metering system comprises a liquid-gas separation tank and a metering tank. An input pipe, a gas outflow pipe and an oil outflow pipe are connected to the liquid-gas separation tank. A first bi-pass ball valve is arranged on the input pipe. A gas flow meter is arranged on the gas outflow pipe. A first thermometer, a second bi-pass ball valve, a first check valve and a third bi-pass ball valve are sequentially arranged on the oil outflow pipe. The oil outflow pipe is connected with the metering tank through a first pipeline, a second pipeline, a third pipeline, a fourth pipeline and a fifth pipeline. The first pipeline, the second pipeline, the third pipeline and the fourth pipeline are sequentially arranged on the portion, between the first thermometer and the second bi-pass ball valve, of the oil outflow pipe. The novel tipping bucket type crude oil metering system has the advantages that the oil-gas separation effect is good, and no impact phenomenon exists; the metering time is shortened, and the metering frequency is increased.

Description

technical field [0001] The invention relates to a crude oil metering system, in particular to a novel tipping bucket crude oil metering system. Background technique [0002] At present, the production measurement methods of conventional oil wells are mainly two-phase separation glass tube oil measurement, two-phase separation instrument measurement, three-phase separation instrument measurement, and oil-gas-water non-separation measurement, etc. The two-phase separation glass tube measures oil, the equipment is simple, but the operation is complicated, and the continuous measurement of the oil well cannot be realized, and the error is large when the production is converted by the intermittent oil measurement method; the mass flowmeter in the two-phase separation instrument measurement method is subject to installation, structure Factors such as wax and gas content are greatly affected, and there are large fluctuations in measurement, and the accuracy of measurement is unstab...
