Embodiment Construction

[0018] A volumetric metering skid for crude oil, such as figure 1 As shown, it includes: hoisting platform 8; the cyclone gas-liquid separation tank 1 installed on the hoisting platform 8, the gas-liquid separator located inside the cyclone gas-liquid separation tank 1, the liquid collection tank 10, the gas-liquid separator located inside the liquid collection tank Float liquid level control mechanism, gas flow meter 17 ( image 3 ), liquid flow meter 6 and pipeline.

[0019] The gas-liquid separator includes a rectifier 12 , a separator 18 , a fixed sleeve 19 , a spiral guide vane 20 and a floating shaft 21 . The separator 18 is located on the inner wall of the cyclone gas-liquid separation tank 1, which divides the cyclone gas-liquid separation tank 1 into upper and lower parts. There is a through hole in the middle of the partition 18 , and a hollow cylindrical fixing sleeve 19 is arranged at the corresponding through hole, and the fixing sleeve 19 forms a sealed connect...

Abstract

The invention relates to a crude oil volume type measuring sledge which comprises a hoisting platform (8), a rotational flow gas and liquid separating tank (1), a liquid collecting tank (10), a gas flow meter (17) and a liquid flow meter (6). The rotational flow gas and liquid separating tank (1), the liquid collecting tank (10), the gas flow meter (17) and the liquid flow meter (6) are mounted on the hoisting platform (8). The side walls of the upper end and the lower end of the liquid collecting tank (10) are respectively provided with a pipeline opening, the upper pipeline opening is connected with the gas flow meter (17) through a pipeline, and the lower pipeline opening is connected with the liquid flow meter (6) through a pipeline. The crude oil volume type measuring sledge is characterized in that a gas and liquid separator is arranged in the rotational flow gas and liquid separating tank (1), and a floating ball liquid level control mechanism is arranged inside the liquid collecting tank (10). The crude oil volume type measuring sledge has the advantages of being simple in structure, few in auxiliary system, small in size, high in measuring precision and accurate in control.

Description

technical field [0001] The invention relates to the technical field of oilfield exploitation, in particular to a metering device for the production fluid volume of a single well in an oilfield. Background technique [0002] The measurement of the fluid produced by a single well in an oilfield is the basic data for oilfield development and an important basis for geological analysis and development plan design. As the oilfield enters a high water-cut development period, the difficulty of oil well measurement is becoming more and more difficult. In addition to the fine analysis of production and the demand for cost reduction and increased efficiency, the requirements for single well measurement technology are also increasing. Therefore, the accuracy of single well measurement technology , Reliability has become a key concern. [0003] The existing oil and gas metering technology can be divided into two categories, one is the traditional metering method, including metering sepa...
