Embodiment Construction
[0036]Based on the actual situation of natural gas production introduced in the background technology, in the process of measuring natural gas flow, we need to consider the influence of condensate oil on the measurement of gas flowmeter, and the flow form of liquid in natural gas. The measurement of natural gas flow should be regarded as It is a gas-liquid two-phase flow measurement problem. For this reason, the present invention proposes the following method and device for measuring the gas-liquid two-phase flow rate of natural gas and condensate oil.
[0037] Such as figure 1 As shown, the gas-liquid two-phase flow measurement method of natural gas and condensate oil / water of the present invention specifically comprises the following steps:
[0038] Step 1, a U-shaped pipe 1 connected to the measuring pipe 12 is arranged at the entrance of the measuring pipe 12. The diameter of the U-shaped pipe 1 is the same as that of the measuring pipe 12, and its height is 3-5 mm of its...
