Abstract
The utility model discloses a flowmeter for ultralow liquid flow measurement. The meansurment status of the current oilfield individual well is as follows: petroleum metering instruments generally adopted in an oilfield are just metering various flowmeters produced at home and abroad, can only measure a full tube of medium which continuously flows but cannot measure a wellhead which outputs oil discontinuously and has low output, therefore, the measure for the oilfield individual well is always in almost blank state. The flowmeter comprises a case body (1); the upper part of the case body (1) is provided with an electrical apparatus control chamber (2) with a lock, and a display instrument (3); the electrical apparatus control chamber (2) is respectively connected with an oil storage tank and a measuring pail (5) through circuits; the oil storage tank (4) is connected with the measuring pail through an electrically operated valve I (7) and a pipeline (6); a liquid level controller (8) is connected above the measuring pail; the oil storage tank is connected with an inlet (9) through an overflow valve and a pipeline; and the measuring pail (5) is connected with an outlet (10) through a pipeline (6). The utility model is used for oilfield individual well measurement.
Description
Technical field:
The utility model relates to a kind of ultralow flow liquid meter flowmeter.
Background technology:
The situation of oil field individual well metering at present: all kinds flowmeter of producing is the oil measurement instrument that generally adopt in the oil field both at home and abroad, but they can only measure the medium of full packages continuous flow, for yield poorly and intermittent fuel-displaced well head can't measure at all, so the oil field individual well metering is in almost blank situation always.
Summary of the invention:
The purpose of this utility model provides a kind of ultralow flow liquid meter flowmeter for the accurate metering of batch (-type) low discharge medium.
Above-mentioned purpose realizes by following technical scheme:
Ultralow flow liquid meter flowmeter, its composition comprises: casing, described casing top is provided with electrical equipment control chamber and Displaying Meter with lock, described electrical equipment control chamber is connected with fuel reserve tank, batch box respectively by circuit, described fuel reserve tank is connected with batch box by motorized valve I, pipeline, described batch box top is connected with the liquid level controller, and described fuel reserve tank is connected with import by surplus valve, pipeline, and described batch box is connected with outlet by pipeline.
Described ultralow flow liquid meter flowmeter; be provided with buffering filter in the described fuel reserve tank; the ball float protection warning device that is provided with in the described fuel reserve tank is connected with surplus valve; described buffering filter is connected with import by pipeline; the below of described batch box is connected with electric oil pump by motorized valve II, and described electric oil pump is connected with outlet by pipeline.
The beneficial effects of the utility model:
1. the utility model has adopted special metering method, so can accurately measure for batch (-type) low discharge medium.Can measure well head day output and cumulative production exactly, thereby solve the difficult problem of intermittent low yield well head metering.
2. this flowmeter has been broken through the design idea of other types flowmeters, solved the mechanical drive flowmeter the gage work that can not finish.Because it does not have mechanical driving part, so processing technology is simple, greatly reduced processing cost, and be easy to debugging.Because these characteristics are easy to promote the use of at oil field shaft mouth, and filled up a blank for one-well metering.

Embodiment:
Embodiment 1:
Ultralow flow liquid meter flowmeter, its composition comprises: casing 1, described casing 1 top is provided with electrical equipment control chamber 2 with lock and Displaying Meter 3, described electrical equipment control chamber 2 is connected with fuel reserve tank 4, batch box 5 respectively by circuit, described fuel reserve tank 4 is connected with batch box 5 by motorized valve I 7, pipeline 6, described batch box 5 tops are connected with liquid level controller 8, described fuel reserve tank 4 is connected with import 9 by surplus valve, pipeline, and described batch box 5 is connected with outlet 10 by pipeline 6.
Described ultralow flow liquid meter flowmeter; be provided with buffering filter 12 in the described fuel reserve tank 4; the ball float protection warning device 11 that is provided with in the described fuel reserve tank 4 is connected with surplus valve 18; described buffering filter 12 is connected with import 9 by pipeline 6; the below of described batch box is connected with electric oil pump 14 by motorized valve II 13, and described electric oil pump 14 is connected with outlet 10 by pipeline.
Described ultralow flow liquid meter flowmeter, described fuel reserve tank bottom is connected with hot-water circulation pipe 15, and described hot-water circulation pipe is connected with water delivering orifice 16, water inlet 17 respectively.
The course of work:
When measured medium when oil-in enters buffering filter, medium is by secondary filtration, guarantees each motorized valve, the action of surplus valve normal switch.This moment, motorized valve I was in normally open, and measured medium flows into batch box by motorized valve I.Motorized valve I and II are subjected to batch box liquid level controller control Push And Release, and every switch once promptly is to have injected a quantitative volume to batch box.
When metering system breaks down; when measured medium can not raise the fuel reserve tank liquid level by the discharge of metering pipeline smoothly; the action of ball float protection warning device; touch the holding circuit microswitch; the protection system circuit start, the overflow motorized valve is opened by normally off, and medium is no longer flowed through the metering system pipeline and is directly entered outlet conduit; warning system is reported to the police simultaneously, and cuts off the metering control system circuit.Press reset button after fault is got rid of, all control circuits recover normal operation.
When measured medium through fuel reserve tank motorized valve I when oil-in enters batch box, liquid level controller magnetic ball float rises along with liquid level and floats, when rising to desired location, control circuit is connected in the built-in dry-reed tube switch action in liquid level controller upper end, the fuel reserve tank motorized valve cuts out, no longer to the batch box injected media, the medium that has entered in the batch box just becomes a standard volume amount.Batch box motorized valve II opens after 5 seconds, electric oil pump starts simultaneously, measured medium is got rid of rapidly, the magnetic ball float descends with liquid level, when reducing to the original position, control circuit is connected in the built-in tongue tube action in liquid level controller lower end, closes motorized valve II and oil pump, and fuel reserve tank motorized valve I opens and carries out the next round metering process after 5 seconds.
