The volume flow can be counted by using the counter to count the reciprocating frequency of the piston and the volume of the cubing pipe.
Description
The utility model relates to petroleum industry department, and a kind of hydraulic control piston type small flowmeter utilizes it can be to the production fluid amount at 0-100m
3The crude oil production well of/d realizes fast, accurately, automatically measure, be specially adapted to high viscosity, low-producing remote producing well.
The open question that high sticking low yield crude oil one-well metering is the puzzlement field production management always.Because metering is inaccurate, time-consuming, be difficult to accomplish the field produces science and management efficiently.The sticking low yield crude oil individual well metering method of the height that uses is to adopt traditional volumetric method at present, it is big that this method exists error in dipping for the metering of the sticking low yield crude oil of height, sometimes can reach 20%, the metering time is long, and the stripper well metering once needs more than two hour remarkable shortcoming sometimes.
In order to overcome above-mentioned shortcoming, a kind of novel hydraulic-control piston type small flowmeter of using the power drive flowmeter work of liquid self is proposed.
The purpose of this utility model is that a kind of hydraulic control piston type small flowmeter will be provided.
According to the purpose of this utility model, a kind of hydraulic control piston type small flowmeter that provides is made up of liquid measure volumescope buret, main pilot operated directional control valve, auxilliary pilot operated directional control valve and overpressure protection mechanism.The volumescope buret is made up of volume metering piston, volume metering cylinder body and O-ring seal; main pilot operated directional control valve is made up of main liquid controlled reversing valve core and main reversing valve body; auxilliary pilot operated directional control valve is made up of auxilliary liquid controlled reversing valve core and auxilliary commutation valve body, and overpressure protection mechanism is made up of spring, valve ball and valve plate.Its principle of work is: the left chamber that enters auxilliary pilot operated directional control valve when the highly pressurised liquid that comes from entering the mouth by main pilot operated directional control valve, promote auxilliary liquid controlled reversing valve core right lateral, liquid enters the right of volume metering piston through the right flow channels of auxilliary liquid controlled reversing valve core, promote the piston left lateral, the liquid on the piston left side is discharged from pipeline by the flow channels on the auxilliary liquid controlled reversing valve core left side; When the volume piston advances to left end, drive the valve rod left lateral of main liquid controlled reversing valve core, the highly pressurised liquid that comes from entering the mouth enters the right chamber of valve body of auxilliary pilot operated directional control valve by the flow channels of main pilot operated directional control valve, promote auxilliary liquid controlled reversing valve core left lateral to stop, liquid enters the left side of volume piston to the left side of valve core flow channels through auxilliary hydraulic control, push body area piston right lateral, the liquid on volume piston the right is discharged from pipeline by the right flow channels of auxilliary liquid controlled reversing valve core.If barrier makes inlet pressure be elevated to the permissible value that overpressure protection mechanism sets for some reason, then valve ball is opened, and liquid stream is directly discharged from pipeline, to the release of fluid flow tube road, plays a protective role.Go round and begin again like this, move in circles, in one moves in circles, the valve rod of main liquid controlled reversing valve core promotes rolling counters forward once, because the volume metering piston of liquid measure volumescope buret and the physical dimension of volume metering cylinder body are certain, so it is certain that each circulation is discharged to the volumetric flow rate of output pipe, just can calculate total volumetric flow rate according to the counting of counter.The flow rate calculation formula of hydraulic control piston type small flowmeter is as (1) formula:
Trial correction can be calculated and use to instrument constant in the formula.
Example: this meter reading is 8001, and last time, meter reading was 8000, and instrument constant is 5.8896, and the time is 1.0 minutes, then
The production fluid amount=(8001-8000) * 5.8896/1.0
＝5.8896m
