The air-drilling gas-into-well three-parameter measuring device solves the problem that smooth straight tube sections need to be arranged at a position of more than 2 m away from the front and the back of the flowmeter, or the measuring precision is influenced in the prior art. The air-drilling gas-into-well three-parameter measuring device can be widely used for measuring the flow rate, the pressure and the temperature of the gas into well in the air drilling, the nitrogen drilling, the foam drilling or the mixed gas drilling.
Description
Technical field:
The utility model relates to a kind of air, nitrogen, foam or mist drilling well, and the flow of gas well gas body is gone in measurement, the air drilling that pressure and temperature is used is gone into gas well gas body three-parameter measuring device.
Background technology:
In the gas drilling process of oil field, must measure three parameters of flow, pressure and temperature of gas well gas body.Before " V " shape internal cone type gas flowmeter occurs, for gasmetry generally is with eddy-current flowmeter or orifice flowmeter, and eddy-current flowmeter and orifice flowmeter in use to require before and after the flow meter must be smooth more than two meters, unobstructed pipeline section.Particularly the requirement of the front end of flow meter is higher, otherwise can have a strong impact on certainty of measurement.Therefore in order to reduce influence as far as possible, generally all pressure gauge and thermometer are placed on after the flow meter flow measurement.Though the part requirement satisfy flow meter is set like this, when gas flows through the vortex street baffle plate of flow meter or orifice plate, all can produces the variation of pressure reduction and temperature difference, thereby have influence on the precision that pressure and temperature is measured.And " V " shape internal cone type gas flowmeter does not in use need smooth, unobstructed straight tube, thus the gas drilling process with in " V " shape internal cone type gas flowmeter is more satisfactory.But " V " shape internal cone type gas flowmeter exists gas flow through the pressure reduction that " V " shape awl back produces and the variation of the temperature difference equally, has influence on the certainty of measurement of the pressure gauge and the thermometer of back.
The utility model content:
The purpose of this utility model provides a kind of air and goes into gas well gas body three-parameter measuring device, this device solves must be smooth without hindrance straight length more than 2 meters before and after the flow meter that exists in the prior art, otherwise can influence the variation that certainty of measurement and " V " shape internal cone type gas flowmeter exist the pressure reduction and the temperature difference equally, have influence on the certainty of measurement problem of the pressure gauge and the thermometer of back.
The technical scheme that its technical problem that solves the utility model adopts is: air drilling is gone into gas well gas body three-parameter measuring device, is made up of flange, measuring tube, thermometer, pressure gauge, signal processor, flow transmitter, V-arrangement cone; The measuring tube two ends are connected to flange, and the flow meter that V-arrangement cone and flow transmitter are formed is installed in the tract of measuring tube, Upstream section front end jointing temp meter, back termination pressure gauge.Because the small-sized obstacle or the bend pipe of the front and back end of " V " shape internal cone type gas flowmeter all can not influence its certainty of measurement, therefore pressure gauge and thermometer are arranged on the certainty of measurement that the flow meter leading portion promptly solves pressure gauge and thermometer, do not influence the certainty of measurement of flow meter again; Flange and measuring tube welding, thermometer and measuring tube welding back screwed connection, pressure gauge and measuring tube, " V " shape cone and flow transmitter are and are welded to connect, welding was understood after flow change biography device inserted measuring tube, and thermometer, pressure gauge, flow change biography device are lead with signal processor and are connected.
The beneficial effects of the utility model are, and are simple in structure, install, easy to use; Pressure gauge and thermometer are placed in the certainty of measurement that the flow meter front end promptly solves pressure gauge and thermometer, do not influence the certainty of measurement of flow meter again.
Description of drawings:
Accompanying drawing is the utility model overall structure schematic diagram.
Among the figure 1, flange, 2, measuring tube, 3, thermometer, 4, pressure gauge, 5, signal processor, 6, flow transmitter, 7, " V " shape cone.
The specific embodiment:
In the accompanying drawings, air drilling is gone into gas well gas body three-parameter measuring device, by flange 1, measuring tube 2, thermometer 3, pressure gauge 4, signal processor 5, flow transmitter 6 and " V " shape cone 7 are formed: flange 1 is welded to connect with measuring tube 2, thermometer 3 and measuring tube 2 welding back screwed connections, pressure gauge 4 and measuring tube 2, " V " shape cone 7 is with flow change biography device 6 and is welded to connect, flow is welded to connect after becoming biography device 6 insertion measuring tubes 2, thermometer 3, pressure gauge 4, flow speed changer 6 is lead with signal processor 5 and is connected, and flow is counted " V " shape inner cone flow meter.
