Detailed description of the invention
Fig. 1 is a kind of structural framing schematic diagram that the embodiment of continuous automatic well-selecting metering system provides of the utility model;
Fig. 2 is a kind of structural framing that the other embodiments of continuous automatic well-selecting metering system provide signal of the utility model Figure.
Specific embodiment
The principles of the present invention and feature are described below in conjunction with attached drawing, example is served only for explaining that this is practical It is novel, it is not intended to limit the scope of the utility model.
The application is illustrated below with reference to Fig. 1 Fig. 2.
As shown in Figure 1, being a kind of structural framing that the embodiment of continuous automatic well-selecting metering system provides of the utility model Schematic diagram, the system include: test separator 1, the first multiple-way valve 2, the second multiple-way valve 3, gas phase measurement loop group 4 and liquid phase meter Measure loop sets 5.
The import of test separator 1 is for obtaining fluid to be batched, for example, the import of test separator 1 can be connected In pipeline road.
Fluid to be batched refers to crude oil, associated gas or the two mixture etc..
The gas vent of test separator 1 is connect with the import of the first multiple-way valve 2, liquid outlet and the second multiple-way valve 3 Import connection.
The petroleum of input test separator 1 obtains crude oil and associated gas, wherein association after the separation of test separator 1 Gas leads to the first multiple-way valve 2, and crude oil leads to the second multiple-way valve 3.
Gas phase measurement loop group 4 includes: the mutually different gas phase measurement loop 41 of at least two measures ranges, each gas phase meter The air inlet in amount circuit 41 is connect with the outlet of the first multiple-way valve 2 respectively.
It should be noted that the quantity and range of gas phase measurement loop 41 can be arranged according to actual needs.
For example, it is assumed that the flow of associated gas can be 100 to 200, then, gas phase measurement loop 41 can be 3, metering Range is 90 to 130,120 to 160,150 to 190 respectively.
It should be understood that the range of each gas phase measurement loop 41 can have the part of overlapping, for example, two gas phase measurement loops 41 measures range can be respectively 100 to 150 and 120 to 160, wherein 120 to 150 be exactly the part being overlapped.Setting weight Folded part can increase the measures range of each gas phase measurement loop 41, the minor change of associated gas is avoided to cause more than first The frequent switching of port valve 2.
Similarly, the range of each gas phase measurement loop 41 can not also be overlapped, for example, two gas phase measurement loops 41 Measures range can be respectively 100 to 150 and 170 to 190.
It should be understood that the specific measures range of each gas phase measurement loop 41 can be arranged according to actual needs, each gas phase The span of the measures range of measurement loop 41 can be mutually the same, can also be different.For example, the meter of 3 gas phase measurement loops 41 Measuring range can be respectively 100 to 200,200 to 300 and 300 to 500.Wherein, the metering of preceding 2 gas phase measurement loops 41 The span of range is identical, is all 100, and the span of the measures range of the 3rd gas phase measurement loop 41 is exactly 200, with preceding 2 gas phases The span of the measures range of measurement loop 41 is different.
Preferably, the measures range of each gas phase measurement loop 41 covers the possible metering of whole of association throughput Value.
It should be noted that possible variable refer to the flow of associated gas to be measured maximum value and minimum value it Between in the range of, including maximum value and minimum value, any one value therein are exactly possible variable.
For example, it is assumed that the possible variable of the flow of associated gas is 100 to 400, measured back then 3 gas phases can be set Road 41, the measures range of this 3 gas phase measurement loops 41 are respectively 100 to 200,200 to 300,300 to 400;Also it can be set 2 gas phase measurement loops 41, the measures range of this 2 gas phase measurement loops 41 are respectively 100 to 300,300 to 400.
