Abstract

The utility model discloses a kind of individual wells to produce liquid metering device, its main feature is that the metering device is formed by the intracorporal screw of case is arranged in, produces liquid pipe, flow instrument, pressure transmitter and threeway valve group, the pipe fitting for producing inlet pipe and outlet pipe composition that liquid pipe is valve connection, and it is horizontally set on lower box;One nozzle of screw is connect by the first control valve with inlet pipe, and another nozzle is connect by the second control valve with outlet pipe;One nozzle of threeway valve group is connect with pressure transmitter, and another nozzle is connected on the second control valve and the connecting line of outlet pipe;The pressure transmitter is arranged on cabinet top, and is to be electrically connected with flow instrument.The utility model has structure simple compared with prior art, easy to use, and measurement accuracy is high, and good reliability is not take up installation space, preferably resolves the measurement problem of tiny flow quantity.

Description

A kind of individual well production liquid metering device
Technical field
It is specifically a kind of based on the individual well of petroleum collection production liquid the utility model relates to oil measurement technical field Measure device.
Background technique
Currently, the calculating of oil production rate is generally used flowmeter during petroleum collection, these flowmeters and differential pressure type, The mainstream flow instrument of the conventional instruments such as positive displacement and float-type composition closed conduct.Due to usually companion during petroleum collection With air and water, cause existing measuring equipment not accurate enough there is measuring, the problems such as poor reliability, accuracy is low, especially It can not be detected at all under tiny flow quantity, bad adaptability, manufacturing cost is high.
Utility model content
A kind of individual well that the purpose of this utility model is in view of the deficiencies of the prior art and designs produces liquid metering device, uses The liquid moment of momentum of pressure transmitter measurement spiral coil structure realizes that petroleum single well produces the measurement of liquid using the moment of momentum, in nothing In the case where any throttling, choked flow piece and intermediary, using the natural turning of pipeline, measurement accuracy is high, preferably resolves The measurement problem of tiny flow quantity, high reliablity, manufacturing cost is low, adaptable, and maintenance workload is small, reaches conveying with metering Perfect unity.
Technical scheme of realizing the purpose of the utility model is that a kind of individual well produces liquid metering device, its main feature is that the meter Amount device is formed by the intracorporal screw of case is arranged in, produces liquid pipe, flow instrument, pressure transmitter and threeway valve group, the production Liquid pipe is the inlet pipe of valve connection and the straight-through pipe fitting of outlet pipe composition, and is horizontally set on lower box;The screw is The spiral coil on cabinet top is set, and one nozzle is connect by the first control valve with inlet pipe, and another nozzle is by the second control valve It is connect with outlet pipe;The pressure transmitter is arranged in threeway valve group and the middle part of cabinet;One nozzle of threeway valve group and pressure Power transmitter connection, another nozzle are connected on the second control valve and the connecting line of outlet pipe;The pressure transmitter setting exists Cabinet top, and be to be electrically connected with flow instrument.
The production liquid pipe is arranged by support in lower box, and two sides outside the enclosure are respectively set in two nozzles.
The utility model has measurement accuracy height compared with prior art, without any throttling, choked flow piece and intermediary In the case where, using the natural turning of pipeline, the measurement problem of tiny flow quantity is preferably resolved, structure is simple, and it is easy to use, Measurement accuracy is high, and good reliability is not take up installation space, and manufacturing cost is low, and adaptable, maintenance workload is small, make conveying with Metering reaches perfect unity.
Detailed description of the invention
FIG. 1 is a schematic structural view of the utility model;
Fig. 2 is Fig. 1 side view;
Fig. 3 is transmitter and flow instrument connection schematic diagram;
Fig. 4 is that the utility model liquid flows to schematic diagram.
Specific embodiment
Refering to 1 ~ Fig. 2 of attached drawing, the utility model by be arranged in cabinet 1 screw 2, produce liquid pipe 5, flow instrument 7, pressure Power transmitter 8 and threeway valve group 9 form, and the liquid pipe 5 that produces is the inlet pipe 51 that valve 6 connects and the straight pipe that outlet pipe 52 forms Part, and it is horizontally set on 1 lower part of cabinet;The inlet pipe 51 and two nozzles of outlet pipe 52 are separately positioned on the two sides outside cabinet 1;Institute Stating screw 2 is the spiral coil that 1 top of cabinet is arranged in, and one nozzle is connect by the first control valve 3 with inlet pipe 51, another Nozzle is connect by the second control valve 4 with outlet pipe 52;The pressure transmitter 8 is arranged in threeway valve group 9 and the middle part of cabinet 1; 9 one nozzle of threeway valve group is connect with pressure transmitter 8, and another nozzle is connected to the connection of the second control valve 4 and outlet pipe 52 On pipeline;The pressure transmitter 8 is arranged on 1 top of cabinet;The production liquid pipe 5 is arranged by support 10 in 1 lower part of cabinet.
Refering to attached drawing 3, the pressure transmitter 8 is to be electrically connected with flow instrument 7.
Refering to attached drawing 4, the utility model is installed and used in this way: liquid pipe 5 will be produced and be serially connected on the oil pipeline in well site, And be fixedly connected respectively with inlet pipe 51 and outlet pipe 52 by bolt, it is then shut off valve 6, opens the first control valve 3 and the second control Valve 4, and the balanced valve among threeway valve group 9 is closed, the shut-off valve on both sides is opened.After oil well works normally, petroleum is logical The inlet pipe 51 for producing liquid pipe 5 is crossed into screw 2, petroleum can generate certain move when flowing through the crooked pipeline of screw 2 Square is measured, at this point, the moment of momentum data input stream amount instrument 7 that pressure transmitter 8 will test, flow instrument 7 is according to the moment of momentum and flow Proportional relation, be converted into the instant playback on flow instrument 7 after flow, according to the flow on flow instrument 7, realize petroleum list Well produces the measurement of liquid, especially carries out high-precision metering to the production liquid of tiny flow quantity.
Above to be only further described to the utility model, not to limit this patent, all is the utility model Equivalence enforcement is intended to be limited solely by within the scope of the claims of this patent.
