The load-position diagram of rod-pumped well needs often test for judging the main foundation of Oil Well Working.Measuring of load-position diagram need be finished by sensor special, and the sensor of each field use mainly divides following three kinds at home at present: hydraulic pressure transducer, activity sensor and fixation of sensor.
Hydraulic pressure transducer is owing to reasons such as complex structure, easy oil leakage, failure rate height, the domestic application scale that do not form.
Activity sensor precision height is widely used at present, but shortcoming is that needs will bump off a well when testing, and the son of checking card needs 2,3 people to cooperate just and can finish.Oil well is had damage, influence output, execute-in-place has potential safety hazard.
Fixation of sensor is installed on every mouthful of rod-pumped well for a long time, does not need stop pumping, the son of checking card during well logging, quick and safety; Shortcoming is that sensor is worked on oil well throughout the year, and sensor drift takes place easily, and the life-span is short, and precision is low, and every mouthful of oil well need be joined a fixed load sensor separately.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of oil well polished rod work of deformation map sensor, this oil well polished rod work of deformation map sensor is analyzed stressing conditions by stressed polished rod diameter variation in the test motion process, thereby test the time does not need stop pumping, the son of checking card, execute-in-place safety, convenience.This oil well polished rod work of deformation map sensor is finished after the measuring task for convenience detach, has saved a large amount of manpower and materials, has improved work efficiency.
For overcoming the above problems, concrete technical scheme of the present utility model is as follows: the sensor beaer is provided with U type mouth, is provided with V-type locating slot and distortion fulcrum groove on a sidewall of U type mouth, flexibly connects the bolt handle on another sidewall of U type mouth; Also be provided with distortion and amplify groove on the sensor beaer, the end that is positioned at distortion amplification groove is provided with jackscrew; Briquetting is connected with the sensor beaer by force column, and jackscrew contacts with the upper surface of briquetting, is provided with resistance strain gage on force column; At the distolateral signal Processing and the communicator of being provided with of sensor beaer, resistance strain gage is connected by lead with signal Processing and communicator.
Described signal Processing and communicator comprise signal Processing and communication module, acceleration chip, wireless receiving and dispatching antenna and power supply.
Described signal Processing and communicator also can increase by a backguy displacement box, are provided with permanent magnet on the surface of backguy displacement box, and backguy displacement box links to each other with signal Processing and communication module by helix.
Described V-type locating slot opening angle is 120 °.
This oil well polished rod work of deformation map sensor adopts distortion fulcrum groove and distortion to amplify groove, make two grooves bee-line place apart produce the fulcrum of distortion for the sensor beaer, make force column produce deflection, the resistance strain gage on it passes to signal Processing and communicator with stressed variation.
Signal Processing and communicator comprise signal Processing and communication module, acceleration chip, wireless receiving and dispatching antenna and power supply.The acceleration chip is used for the displacement of survey sensor, and signal Processing and communication module will be handled by the resistance strain gage signal that lead passes, and be transferred in the external unit by the mode of wireless receiving and dispatching antenna with wireless telecommunications then.
In sum, this oil well polished rod work of deformation map sensor is analyzed stressing conditions by stressed polished rod diameter variation in the test motion process, thereby test the time does not need stop pumping, the son of checking card, execute-in-place safety, convenience.
Description of drawings
Fig. 1 is the structural representation of oil well polished rod work of deformation map sensor.
Embodiment
As shown in Figure 1, a kind of oil well polished rod work of deformation map sensor, sensor beaer 1 is provided with U type mouth, is provided with V-type positioning groove 13 and distortion fulcrum groove 7 on a sidewall of U type mouth, flexibly connects bolt handle 2 on another sidewall of U type mouth; Also be provided with distortion and amplify groove 8 on sensor beaer 1, on sensor beaer 1, the end that is positioned at distortion amplification groove 8 is provided with jackscrew 6; Briquetting 4 is connected with sensor beaer 1 by force column 3, and jackscrew 6 contacts with the upper surface of briquetting 4, is provided with resistance strain gage 5 on force column 3; At the distolateral signal Processing and the communicator 10 of being provided with of sensor beaer 1, resistance strain gage 5 and signal Processing and communicator 10 are connected by lead.
Described signal Processing and communicator 10 comprise signal Processing and communication module 17, acceleration chip 11, wireless receiving and dispatching antenna 9 and power supply 12, signal Processing and communication module 17 are used for the signal of resistance strain gage 5 is handled, by wireless receiving and dispatching antenna 9 signal is issued external unit then, power supply 12 provides required electric weight for signal Processing and communicator 10.
Described signal Processing and communicator 10 also can increase by a backguy displacement box 15, are provided with permanent magnet 16 on the surface of backguy displacement box 15, and backguy displacement box 15 links to each other with signal Processing and communication module 17 by helix 14.
Described V-type locating slot 13 opening angles are 120 °.
Its course of work is: sensor beaer 1 utilizes resilient material to process, be clamped in oil well polished rod 18 in the U type mouth V-type locating slot 13 of sensor beaer 1 by spiral handle 2, the polished rod of operation is subjected to the pulling force effect, after diameter changes, the sensor beaer 1 of resilient material will be experienced the vary in diameter of oil well polished rod 18, the thin-walled at positioning groove 7 places is a fulcrum, amplify the leverage of groove 8 by distortion, the jackscrew 6 that makes distortion amplify the end of groove 8 produces minute movement, briquetting 4 is produced snap-in force, make force column 3 produce distortion.By the mode of adhering resistance strain sheets on elastic body force column 3, form a Wheatstone bridge, measure elastomeric situation of change, be converted to the stressed load value of polished rod after the demarcation calibration.Sensor internal also is equipped with signal Processing and devices such as wireless communication module and power supply, is used for detecting handling test data, and test result is transferred in the portable testing apparatus by wireless communication mode.
