Description
Technical Field
The invention relates to a method for prolonging the service life of a battery in a testing plunger, belonging to the technical field of underground instruments.
Background
The testing plunger is used for testing the underground pressure and temperature of the plunger well and mainly comprises the testing plunger and a wellhead wireless device, and the testing plunger has the same overall dimension as a common drainage plunger used in the plunger well. When the plunger well is opened, the testing plunger can move upwards from the bottom of the well to the well head under the push of airflow, and accumulated liquid in the plunger well is discharged in the process; when the plunger well is shut in, the test plunger can fall to the bottom of the well under the action of self gravity. Under the control of the well switching period of the plunger well, the test plunger periodically reaches the well head from the well bottom, and then reaches the well bottom from the well head. The testing plunger is internally provided with a temperature and pressure measuring circuit and a wireless communication assembly, and the testing plunger can continuously test the pressure and the temperature in the well in the moving process. After the test plunger reaches the wellhead, the connection with the wellhead wireless device is established through the wireless communication assembly, data in the previous period of the test plunger is transmitted to the wellhead wireless device, and then the data are transmitted to the user computer through the wellhead wireless device through GPRS.
Due to the limitation of application environment, the testing plunger can only be powered by a disposable high-temperature battery. Therefore, under the condition that the battery capacity is limited, how to reduce the consumption of electric energy in the testing plunger is important to prolong the working time of the testing plunger in the well. The battery consumption of the wireless communication assembly in the test plunger is hundreds of times of that of circuits for measuring temperature and pressure and the like. Therefore, the primary task in controlling the power consumption of the test plunger is to optimize the operating mode of the wireless communication assembly. The working mode of the wireless communication assembly in the test plunger in the prior art is to judge whether the test plunger is about to reach a wellhead or not in advance according to pressure and temperature data, start a wireless communication function in advance when the test plunger is about to reach the wellhead, continuously send a wireless handshake signal, and establish communication connection with a wellhead wireless device until the test plunger reaches a certain distance away from the wellhead wireless device. Because the test plunger is when being close the well head, the test plunger under the effect of air current, generally can make a round trip to oscillate half an hour to about several hours near the well head, and the wireless function of test plunger can be opened always this moment. The power consumption speed in the test plunger is very high, the battery needs to be replaced frequently, and the running cost is high. The operation of replacing the testing plunger battery is very complicated, the wellhead blowout preventer needs to be disassembled after the well is shut down, the workload is high, and potential safety hazards exist. Therefore, the prior art still has the defects and needs to be further improved.
Disclosure of Invention
The invention aims to provide a method for prolonging the service life of a battery in a testing plunger so as to prolong the service life of the battery in the testing plunger and the period of replacing the battery, and improve the running economy of the testing plunger, thereby overcoming the defects in the prior art.
In order to achieve the purpose, the invention adopts the following technical scheme:

In the method for prolonging the service life of the battery in the test plunger, the starting of the wireless communication assembly in the test plunger is controlled by a Hall sensor arranged in the test plunger and magnetic steel arranged in a wellhead blowout prevention pipe; when the testing plunger moves upwards to the wellhead and approaches to the magnetic steel in the wellhead blowout prevention pipe, the distance between the Hall sensor in the testing plunger and the magnetic steel in the wellhead blowout prevention pipe is very close, and when the Hall sensor senses that the magnetic field intensity of the magnetic steel is larger than a set value, the battery in the testing plunger supplies power for the wireless communication assembly.
In the method for prolonging the service life of the battery in the test plunger, the magnetic steel in the wellhead blowout preventer is bonded at the bottom of the cavity of the spring seat in the wellhead blowout preventer, and the spring seat is made of a non-magnetic material so as to avoid shielding magnetic field signals.
In the method for prolonging the service life of the battery in the test plunger, magnetic field strength test software is installed in the test plunger; when the magnetic field intensity sensed by the Hall sensor is larger than a set value and keeps stable and unchanged within a set time, the wireless communication assembly in the testing plunger is started, so that the situation that the wireless communication assembly in the testing plunger is not required to be tested to work is prevented, and the wireless communication assembly is continuously started to cause electric energy consumption.
In the method for prolonging the service life of the battery in the test plunger, after the test plunger is captured, the wireless communication assembly in the test plunger is started and connected with the wellhead wireless device, data in the previous period of the test plunger is transmitted to the wellhead wireless device, and then the data is transmitted to the user computer through the wellhead wireless device through GPRS.
According to the method for prolonging the service life of the battery in the test plunger, the release catcher is manually controlled after data transmission is completed, the test plunger falls due to self weight after being released, a magnetic field signal sensed by the Hall sensor is weakened, when the magnetic field intensity is smaller than a set value, the wireless communication assembly in the test plunger is closed, the power consumption of the test plunger is extremely low, and a pure test mode is entered.
Due to the adoption of the technical scheme, compared with the prior art, the testing plunger in the invention does not start the wireless communication function every time the testing plunger reaches the vicinity of the wellhead wireless device like the prior art, but starts the wireless communication component in the testing plunger to acquire the testing data of a previous period of time by manually operating the catcher when the testing data is required according to the requirements of users. The test data interval can be days or months; when the test plunger is not tested, the wireless communication assembly in the test plunger is not started, so that electric energy is not consumed, the power consumption of the test plunger is greatly reduced after improvement, the continuous working time of a battery of the test plunger in the underground can be as long as more than 1 year, the service life of the battery is greatly prolonged, meanwhile, the replacement period of the battery in the test plunger is also prolonged, the long-term operation of the test plunger is realized, and the operation cost of the test plunger is reduced.

Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples.
According to the method for prolonging the service life of the battery in the test plunger, as shown in figure 1, a catcher 6 is arranged at a wellhead, the test plunger 5 reaching the wellhead is caught and fixed through manually controlling the catcher 6, and the test plunger 5 is prevented from oscillating back and forth near the wellhead under the action of a wellhead damping spring and air flow, so that the working stability of a wireless communication assembly in the test plunger 5 is kept, and the time of consuming electric energy by the wireless communication assembly is shortened. Starting a wireless communication assembly in the testing plunger 5 is controlled by a Hall sensor 4 arranged in the testing plunger 5 and a magnetic steel 3 arranged at the bottom of a wellhead blowout prevention pipe 1; when the test plunger 5 ascends to the wellhead and approaches the bottom of the wellhead blowout preventer 1, the Hall sensor 4 in the test plunger 5 is very close to the magnetic steel 3 at the bottom of the wellhead blowout preventer 1, and when the magnetic field strength sensed by the Hall sensor 4 is greater than a set value, the battery in the test plunger 5 supplies power for the wireless communication assembly. The magnet steel 3 at the bottom of the wellhead blowout preventer 1 is bonded at the bottom of the cavity of the spring seat 2 in the wellhead blowout preventer 1, and the spring seat 2 is made of a non-magnetic-conductive material so as to avoid shielding magnetic field signals. The test plunger 5 is internally provided with magnetic field intensity test software; when the magnetic field intensity sensed by the Hall sensor 4 is larger than a set value and keeps stable and unchanged within a set time, the wireless communication assembly in the testing plunger 5 is started, so that the situation that the wireless communication assembly in the testing plunger 5 is uninterruptedly started to consume electric energy when the wireless communication assembly works is avoided. After the test plunger 5 is captured, the wireless communication assembly in the test plunger 5 is started and connected with the wellhead wireless device 7, data in the previous period of the test plunger 5 is transmitted to the wellhead wireless device 7, and then the data is transmitted to the user computer through the wellhead wireless device 7 through GPRS. After data transmission is completed, the catcher 6 is manually controlled and released, the testing plunger 5 falls due to self weight, a magnetic field signal sensed by the Hall sensor 4 is weakened, when the magnetic field intensity is smaller than a set value, the wireless communication assembly in the testing plunger 5 is closed, the testing plunger 5 consumes extremely little electric energy at the moment, and the testing plunger enters a pure testing mode.
When the method is concretely implemented;
the invention mainly comprises a testing plunger 5 and a wellhead wireless device 7, wherein the testing plunger 5 is provided with a conventional temperature and pressure measuring circuit, a wireless communication component and a battery component, and a Hall sensor 4 is arranged at the top end wireless communication component accessory, so that the external magnetic field intensity can be sensed. The interior of a spring seat 2 in the wellhead blowout prevention pipe 1 is hollowed to be used for mounting magnetic steel 3, and the spring seat 2 is processed by non-magnetic-conductive materials to avoid shielding magnetic field signals. The catcher 6 can catch the test plunger 5 by manual operation when the test plunger 5 reaches the wellhead.
The wireless communication function of the test plunger 5 is not started in most working time, and when the test plunger 5 needs to be started to obtain test data, a user can select to open the catcher 6 when the test plunger 5 moves upwards. Catch by catcher 6 when test plunger 5 reachs the well head, hall sensor 4 is very close from magnet steel 3 distance in the spring holder 2 this moment, and the magnetic field intensity of response is big, simultaneously because test plunger 5 has been caught no longer removes, and fixed in position between hall sensor 4 and the magnet steel 3, the magnetic field intensity signal that hall sensor 4 sensed keeps stable. Software judgment program is added in the testing plunger piston 5, if the magnetic field intensity is larger than a set value, and meanwhile, the testing plunger piston 5 is kept stable and unchanged within a period of time, so that the fact that the testing plunger piston 5 is located at a wellhead and a user needs to copy out test data can be judged. At this point, the wireless communication function is activated again, and the test data of a previous period of time is transmitted to the wellhead wireless device 7. After receiving the data, the user releases the test plunger 5 by operating the catcher 6, the test plunger 5 falls, the magnetic field signal is weakened and is no longer stable and unchanged, at the moment, the wireless function in the test plunger 5 is closed, and the pure test mode is entered.
In this mode of operation, the test plunger 5 no longer activates the wireless communication function each time it reaches the vicinity of the wellhead wireless device 7 as before, but rather activates the wireless communication function by manual operation at intervals (which may be days or months depending on user requirements) to obtain test data for a previous period. Therefore, the power consumption of the testing plunger 5 is greatly reduced, and the working time of the testing plunger 5 can be more than 1 year.
By adopting the technology, the invention greatly reduces the starting time of the wireless communication assembly in the testing plunger, greatly reduces the power consumption of the testing plunger, prolongs the replacement period of the battery in the testing plunger, realizes the long-term operation of the testing plunger and reduces the operation cost of the testing plunger.
