Problems solved by technology

[0004] The object of the present invention is to provide a natural gas single well multi-phase flow metering equipment to solve the problems in the prior art that the equipment is huge, the construction is complicated, the use cost is high, and all single wells cannot be continuously metered. A large number of gas wells with intermittent liquid production such as bubble row and plunger gas lift cannot be effectively measured, and the lack of liquid production data of a single well affects the effective development of drainage and gas recovery, high testing costs, and cannot be widely used.

Embodiment 1

[0027] A natural gas single well multiphase flow metering equipment, such as figure 1 As shown, including gas-liquid separation container system, gas metering system, liquid metering control system, pressure measuring element, temperature measuring element and signal processing system;

[0028] The gas-liquid separation container system includes an inlet connection flange 1, an inlet pipe 2, a liquid inlet baffle 3, sawtooth 4, an inclined baffle 5, a separation container bottom plate 6, a gas-liquid separation net 7, a separation container topping 8, a separation The container cylinder 9, the separator 10 and the bottom plate of the separation chamber 45; the separation container topping 8 is welded on the upper part of the separation container cylinder 9, the separation container bottom plate 6 is welded on the bottom of the separation container cylinder 9, and the gas-liquid separation net 7 is welded on the separation container cylinder 9 The upper part, the inlet connecti...

Embodiment 2

[0036] A single-well multiphase flow metering device for natural gas, similar to Embodiment 1, the difference is that the metering device also includes a box assembly, and the box assembly includes a box shell 43; a gas-liquid separation container system, a gas The metering system, the liquid metering control system, the pressure measuring element, the temperature measuring element and the signal processing system are arranged in the box shell 43 .

[0037] In this way, all its measuring components are placed in the box shell 43, so as to prevent the measuring system from being exposed to the wind and the sun, and to avoid premature aging and damage of the measuring instruments caused by environmental factors.

Embodiment 3

[0039] A single-well multiphase flow metering device for natural gas is similar to Embodiment 2, the difference is that the box assembly also includes an insulation layer 44 , and the insulation layer 44 is attached to the inner wall of the box shell 43 .

[0040] In this way, it adopts the self-insulation design idea, which can avoid the damage to the measurement system (especially avoid the freezing of the liquid in the separation container) under the low temperature working conditions in the wild in the north, so that the instrument is still not easy to be damaged in the low temperature environment. .

Description

technical field [0001] The invention relates to the technical field of metering equipment, in particular to a natural gas single well multiphase flow metering device. Background technique [0002] At present, natural gas fields adopt inter-well connection and wellhead wet gas metering technology, and single-phase flowmeters are used to measure the gas production of a single well, and there is no single-well liquid production measurement. As the gas field enters the stable production stage, the lack of single well fluid production data restricts the fine management of gas wells and the optimization and effect evaluation of drainage and gas production measures. In order to grasp the water production of gas wells and evaluate the effect of key well measures, skid-mounted separation metering devices are often used to measure the gas-liquid production of gas wells on site. However, the equipment is huge, complicated to construct, and expensive to use, and cannot continuously meas...
