Description
Technical field
The utility model belongs to the oilfield test device, particularly relates to oil well liquid level restoring method automatic oil-measuring device.
Background technology
Current well fluid level field tests, some testing equipments can only be in the situation that there be casing pressure (being greater than 0.3MPa) just can be tested the liquid level data, on the scope of application with obvious limitation; Some testing equipments are by automatically discharging the gas sounding, and continuous automatic measurement easily causes gas vent to be stopped up by dirt in well, not only exists potential safety hazard, also can cause pollution to a certain degree to the oil well surrounding environment; The associativity of some testing equipments and miscellaneous equipment is poor, can not form complete closed-loop control system; Wherein most important one is exactly that field condition is used theftproof performance poor, easily is subject to artificial destruction.For above in esse problem, a kind of ATE that can integrate continuity, safety, associativity is needed in liquid level test field, oil field badly.Between oil well intelligent, take out and the radiation source long distance control system is exactly a solution of having done for these problems.Prior art equipment exists following not enough simultaneously: 1, liquid level test unit and communication control unit split cause the field control casing more, more in disorder.2, be installed on the liquid level test unit of oil well casing mouth, must draw high-voltage power-line and signal and communication line from control module, well head draws high-voltage power-line and has potential safety hazard.3, the liquid level test cellular installation, in well head, affects the oil well operation process, to oil well heat wash, the construction of dosing and maintenance activity makes troubles; Liquid level test equipment is easily damaged unintentionally.4, the liquid level test unit box is arranged separately in well head, and anti-theft effect is poor, easily is subject to artificial destruction.
Summary of the invention
The utility model is intended to overcome the deficiencies in the prior art, and a kind of oil well liquid level restoring method automatic oil-measuring device is provided.
Oil well liquid level restoring method automatic oil-measuring device of the present utility model, be to consist of central processing unit, remote data transport module, intelligent monitored control module, oil well liquid level automatic test module, Switching Power Supply, GPRS module and display are connected with central processing unit respectively.
As further improvement of the utility model, the oil well liquid level test module connects the oil well casing interface by the infrasound transmitting catheter.
As further improvement of the utility model, the infrasound transmitting catheter is high-pressure rubber pipe, is provided with sound between infrasound transmitting catheter and oil well casing interface and receives amplifying device.
As further improvement of the utility model, the GPRS module connects remote terminal.
As further improvement of the utility model, Switching Power Supply connects field power supply by transformer.
Oil well liquid level restoring method automatic oil-measuring device of the present utility model, utilize the infrasonic wave pulse signal to arrive oil well liquid level through oil sets annular space, realize that liquid level monitors automatically, continuous measurement, safety and environmental protection, this device structure adopts brand-new antitheft theory design simultaneously, guarantee that well head is without stube cable and signal cable, wellhead component and structure are not easy to suffer artificial destruction, all adopt the modulation conformity mode, design of major parts is arrived to the Comprehensive Control case away from well head, safe antitheft, and do not affect field operation.This matched with devices automatic closed loop control system, can make oil well remain under best submergence state moves, in the situation that output and efficiency optimization, automatic or the Long-distance Control by scene, change jig frequency or the rotating speed of computer collecting system, oil well is reached and adopt the adaptive equalization state of liquid ability and fluid supply capacity, thereby reached the purpose that volume increase lowers consumption.
This device adopts the anti-theft type Structured Design, and the well head place is without unnecessary article, and succinct clean, test module directly is configured in control cabinet, good anti-theft effect; The well head place is without stube cable, and non-contact electric danger, guarantee personal security; Test does not affect normal operation, and the sleeve pipe place joint of directly dismantling gets final product; Be not subject to low temperature effect, equipment is in control cabinet, and winter, convenient the realization heated; Not overhead just affected by sleeve opening; The hermetically sealed modularized design of liquid level test device, safe and efficient; Infrasonic wave pulse excitation mode, oil well has or not casing pressure can realize the automatic liquid level measurement; Liquid level echo self-identifying technology, this technology can guarantee that equipment identifies the liquid level echo voluntarily, directly calculates liquid level numerical value, this is the prerequisite that realizes that automated closed-loop is controlled.
The accompanying drawing explanation
Fig. 1 is oil well liquid level restoring method automatic oil-measuring device structured flowchart of the present utility model.
The specific embodiment
Oil well liquid level restoring method automatic oil-measuring device of the present utility model as shown in Figure 1, be to consist of central processing unit 1, remote data transport module 2, intelligent monitored control module 3, oil well liquid level automatic test module 4, Switching Power Supply 5, GPRS module 6 and display 7 are connected with central processing unit 1 respectively.
Oil well liquid level test module 4 connects oil well casing interface 9 by infrasound transmitting catheter 8.Infrasound transmitting catheter 8 is high-pressure rubber pipes, is provided with sound between infrasound transmitting catheter 8 and oil well casing interface 9 and receives amplifying device 10.
Oil well liquid level restoring method automatic oil-measuring device of the present utility model: set interval as required, automatically test in real time the oil well liquid level curve, and automatically identify the hydrodynamic face amount, and fluid value is real-time transmitted between intelligent control module realization automatically and takes out on off control; Also can directly real-time fluid value wireless transmission (GPRS) be arrived to control centre's computer software, realize artificial intelligence control start and stop; The following parameter of on-site data gathering module Real-time Collection: real-time fluid value, casing pressure value (can increase the parameters such as merit figure, the degree of balance, voltage, electric current, power, power consumption according to customer requirement); Upper computer software and control terminal show below parameter in real time: in real time fluid value, casing pressure value (can increase the parameters such as merit figure, the degree of balance, voltage, electric current, power, power consumption) according to liquid level data in real time both can with the frequency converter combination, automatically adjust frequency converter frequency, realize the steady and continuous energy-saving run, also can be set the reasonable cycle of operation, control module is controlled and is realized taking out between intelligence according to instruction; While automatically starting oil pumper, field control cabinet acousto-optic is reported to the police, and reminds the field personnel to note, guarantees safety.
