Multi-channel distributing valve

Abstract

The invention discloses a multi-channel distributing valve. The valve comprises a valve body and a valve element located in an inner cavity of the valve body, wherein a plurality of inlets and two outlets are formed in the valve body, an inner channel is formed in the valve element, an outer channel is formed between the valve element and the valve body, the inner channel is communicated with one inlet and a first outlet of the two outlets and disconnected from a second outlet, and the outer channel is communicated with the rest inlets and the second outlet and disconnected from the first outlet; the valve further comprises a driving part for driving the valve element to act, and all the inlets 11 are located in the moving path of the valve element, so that all the inlets 11 can be communicated with the inner channel 22 during moving of the valve element 2. When the valve is used for metering the single well fluid production capacity, each inlet is communicated with each oil well, the first outlet is used for metering, the single well incoming fluid can be measured by controlling the driving part only, the operation is convenient, the labor intensity is greatly reduced, meanwhile, the driving part can drive the valve element to move continuously, continuous metering is realized, so that the accuracy of metering results is improved, and errors are reduced.

Description

technical field [0001] The invention relates to the technical field of natural gas transportation, in particular to a multi-channel distribution valve. Background technique [0002] In the field of natural gas acquisition, the liquid production rate of oil well is an essential parameter in oilfield development, production and geological analysis. The accuracy of oil well production rate directly affects the adjustment of oilfield development, geological analysis and production process plan. [0003] The traditional oil well single-well fluid production metering method is to use the metering process manifold to match the vertical separator metering method, and design measuring stations in areas where the oil wells are relatively concentrated. At the same time, multiple sets of upper and lower valves are combined to form a manifold. , connected to the vertical separator. When measuring, it is necessary to manually switch the upper and lower valves to pass the liquid productio...

Problems solved by technology

More importantly, the liquid production rate of a single well is converted by measuring the oil production rate in a specific period of time. The above-mentioned measurement process is difficult to achieve continuous, resulting in measurement errors as high as 10% to 20%.
