Description
Technical field:
The utility model relates to the oilfield test field, particularly a kind of liquid level self-operated measuring unit.
Background technology:
The oilfield test field uses ATE that the well head liquid level is tested mostly at present.And on-the-spot test only just can be carried out shaft mouth test liquid level data under the situation that casing pressure or low casing pressure (below the 0.3MPa) are arranged, and has tangible limitation on the scope of application; Existing equipment is by automatically discharging the gas sounding, and continuous automatic measurement causes gas vent to be stopped up by dirt in the well easily, and can cause to a certain degree pollution to environment; Also there is potential safety hazard; Existing equipment is single liquid level test device, and is relatively poor with the associativity of miscellaneous equipment, can not form complete closed-loop control system, function singleness.
The utility model content:
Can't measure automatically under no casing pressure or low casing pressure situation in order to solve prior art; gas vent is stopped up by dirt in the well easily; and discharge the deficiency of gaseous contamination environmental problem; the utility model provides a kind of oil well liquid level self-operated measuring unit, and this installs the advantage that realization oil well is continuous, efficient, energy-conservation, protect environment, safety in production.
The purpose of this utility model is achieved by the following technical solution: this device air pump connects air chamber, air chamber is built-in with pressure sensor, air chamber connects well head by valve and wellhead connector, valve is controlled by the internal controller data processing module, wellhead connector is built-in with sound and receives amplifying device, sound receives amplifying device and connects sound transducer and internal controller data processing module successively, the internal controller data processing module is connected with air pump and peripheral control unit and display, and peripheral control unit and display are connected with the GPRS wireless module.
The utlity model has following effect: owing to adopted technique scheme, air pump gives the interior pressure of air chamber all the time than borehole pressure big (greater than 0.3Mpa), and having overcome prior art is not having the problem that pressure or low pressure can not be tested; And the moment of the valve open of this device make and produce sound in the air chamber, transmission sound is returned a signal behind the liquid level and is received amplifying device to sound, measures automatically; Air chamber sound excites and has saved the human factor that prior art use sound bullet excites simultaneously, the corresponding dirt that does not exist bearing band falls in the well, make gas vent dirt can not occur, let alone dirt blocking problem in the well, just there is not environmental pollution phenomenon yet.
Description of drawings:
Accompanying drawing 1 is a structural representation of the present utility model.
In the accompanying drawing: the 1-air pump, the 2-air chamber, 3-internal controller data processing module, the 4-sound transducer, the 5-air valve, 6-sound receives amplifying device, 7-peripheral control unit display, 8-GPRS wireless module, 9-well head, 10-wellhead connector, 11-pressure sensor.
The specific embodiment:
Below in conjunction with embodiment the utility model is further described:
As shown in Figure 1, this device air pump 1 connects air chamber 2, and purpose can suppress for air chamber 2 by air pump 1, makes that the pressure in the air chamber 2 remains at more than 0.3, overcomes the problem that nothing is pressed or low pressure can not be tested in the prior art; Air chamber 2 is built-in with pressure sensor 11, be used to measure the pressure that air chamber 2 internal pressures and air pump 1 inflate for air chamber 2, air chamber 2 connects well head 9 by valve 5 and wellhead connector 10, valve 5 is opened and is closed by 3 controls of internal controller data processing module, wellhead connector 10 is built-in with sound and receives amplifying device 6, the voice signal that is used to receive and amplifies that air chamber 2 produces and return by liquid level, sound receives amplifying device 6 and connects sound transducer 4 and internal controller data processing module 3 successively, sound transducer 4 converts the speech simulation signal that sound receives amplifying device 6 reception amplifications data signal to and is sent to internal controller data processing module 3,3 pairs of data of internal controller data processing module are handled, internal controller data processing module 3 is connected with air pump 1, air valve 5 and peripheral control unit and display 7, and peripheral control unit and display 7 are connected with GPRS wireless module 8, running parameter is set and shows curve to automatic equipment by peripheral control unit and display 8, store to remote data center by GPRS wireless module 8 wirelessly transmitting datas.
During concrete operations, should place well head 9 by device, connect power supply, peripheral control unit display 7 is started working, control internal controller data processing module 3, open valve 5, pressure sensor 11 writes down air chambers 2 internal pressures at this moment, air chamber 2 internal pressures and borehole pressure value equal and opposite in direction, force value has been surveyed, peripheral control unit display 7 control internal controller data processing modules 3 valve-offs 5, and control internal controller data processing module 3 work, at first control air pump 1 to air chamber 2 inflations, by pressure sensor 11 readings, make air chamber 2 internal pressures greater than the force value 0.3Mpa before the valve-off 5, be that air chamber 2 pressure are greater than borehole pressure 0.3Mpa, inflate finish after, internal controller data processing module 3 one control air valve 5 are opened and are exitted, the venting of moment, because air chamber 2 internal pressures are different with borehole pressure, make and produce gas pulsation in the air chamber 2, and then generation sound, send in the well by wellhead connector 10, sound receives to be gathered for sound transducer 4 after amplifying device 6 receives the sound echo of returning from the shaft bottom liquid level, sends into internal controller data processing module 3 afterwards and handles and storage, and the data after the processing are sent to peripheral control unit and display 7 again, show echo curve and liquid level change situation, by GPRS wireless module 8 test data is sent to the remote data center storage again.
