Description
Technical Field
[0001] The invention belongs to the technical field of petroleum engineering and instrument detection, and in particular relates to a pulse generator testing device for oil drilling. Background Art
[0002] The oil drilling pulse generator test equipment is mainly used to simulate the real drilling environment and perform functional performance testing and durability evaluation on downhole instruments such as oil drilling pulse generators.
[0003] Chinese invention patent CN101749010A discloses a mud pulse generator test device, including a square wave generating circuit, a capacitor module, a transformer module, an oscillation circuit, a power supply module, a pulse regulating circuit and a driver testing module, wherein the output of the pulse regulating circuit is respectively connected to a discharge pulse control circuit, a holding pulse control circuit and a driver testing module. The test device can test two downhole instruments, the driver and the mud pulse generator, and use a pulse signal with an adjustable duty cycle to simulate the command of the downhole probe. The command is input to the driver testing module to test the driver on the one hand, and is input to the discharge pulse control circuit and the holding pulse control circuit on the other hand, and generates a corresponding control signal to control the operation of the mud pulse generator.

[0083] When in use, the required medium is placed in the medium tube 20 as needed, and then another required medium is filled between the heating element 18 and the top plate 13, and then the pulse generator 1 and multiple sensors 21 are started through the controller 26. During the test, the performance of the pulse generator 1 emitting pulse signals in a variety of different media is detected in real time through the multiple sensors 21.
[0084] During the operation of the pulse generator 1, the controller 26 controls the motor to rotate. When the motor rotates, it drives one of the auger screws 23 and the third gear 24 to rotate. When the third gear 24 rotates, it drives the second gear 15 to rotate. When the second gear 15 rotates, it drives multiple first gears 14 and third gears 24 to rotate. During the rotation of multiple first gears 14 and third gears 24, they drive multiple rotating shafts 10 and auger screws 23 to rotate.

[0085] During use, the controller 26 controls the heating tube 19 to heat the working medium on the top of the heating element 18. The working medium expands in volume after being heated, so that the test equipment is in a high temperature and high pressure state. During the test, the pressure gauge 29 and the pressure sensor are used to observe the pressure changes in the test equipment in real time. When the pressure is too high or insufficient, the pressure is released or pressurized into the test equipment through the connecting pipe 28, thereby fully testing the working conditions of the pulse generator 1 at different temperatures and pressures.
[0086] The motor is connected to the third gear 24 in the gear box 25 through the top of the auger screw 23 fixed thereon. When the motor is started, it will drive the auger screw 23 connected thereto to rotate, and the third gear 24 will mesh with the second gear 15, thereby driving all the first gears 14 and the remaining auger screws 23 to rotate synchronously. The first gear 14 acts on the rotating shaft 10 to rotate multiple first power rings 6 and second power rings 7, and perform multi-angle extrusion tests on the pulse generator 1. Temperature and medium control, the heating tube 19 inside the heating element 18 generates heat under the command of the controller 26 to heat the working medium under the top plate 13 to the required temperature. The medium pipe 20 in the shell 16 can be filled with different media to simulate a variety of working conditions. At the same time, the circulation flow of the medium is realized through the auger screw 23 in the circulation pipe 22 to ensure that the medium is fully in contact with the pulse generator 1 and affects its performance. Pressure regulation and monitoring, after the working medium in the heating element 18 expands due to heat, the pressure The force gauge 29 and the pressure sensor monitor the pressure changes inside the equipment in real time. If the pressure is too high or insufficient, the connecting pipe 28 can cooperate with the external pressure control device to automatically release or supplement the pressure to simulate the working state of the pulse generator 1 under different temperature and pressure environments. The structure is optimized, the first extrusion inner ring 2 and the second extrusion inner ring 3 are designed as a triangular structure, and the first roller 8 and the second roller 9 are arranged at the vertex position of the triangular structure, which can more effectively reduce friction and improve transmission efficiency, while ensuring that the pulse generator 1 is subjected to uniform pressure from multiple directions. The operation of the entire system is uniformly managed by the controller 26, including the working state of the pulse generator 1, the heating tube 19, the motor and various sensors 21 such as the temperature sensor. During the test, data is obtained through the sensor 21, and the controller 26 adjusts the equipment parameters according to these real-time data to achieve accurate performance testing of the pulse generator 1 under different media, temperature and pressure conditions.
[0087] It can accurately simulate various working conditions. Different media can be filled through the medium tube 20 to realize the performance test of the pulse generator 1 in various medium environments. At the same time, the temperature is controlled by the heating element 18 and the heating tube 19, and the auger screw 23 is used to drive the medium to circulate to ensure that the working medium is in full contact with the pulse generator 1. It can effectively simulate the high temperature and high pressure state in real work. It can conduct multi-dimensional and all-round evaluation. It adopts multiple first extrusion inner rings 2, second extrusion inner rings 3 and roller structures to perform extrusion tests on the pulse generator 1 from different angles to fully reflect its impact resistance and stability under complex stress conditions. It has intelligent control and monitoring. The controller 26 integrates the operation and monitoring functions of the entire system, can automatically control the operation of the motor and the heating tube 19, and receive and analyze the data of the sensor 21 in real time, so as to accurately adjust the pressure, temperature and other parameters to ensure the safety and accuracy of the test process. It has efficient transmission and anti-friction design. The triangular structure of the first extrusion inner ring 2 and the second extrusion inner ring 3 and the roller design are conducive to reducing friction and improving the operation efficiency of the equipment. At the same time, the gear meshing system between the various components makes the power transmission more uniform and stable. The flexible pressure regulation mechanism connects the external pressure control equipment through the connecting pipe 28, and can quickly adjust the pressure inside the test equipment according to actual needs to adapt to different test conditions, which helps to have a deeper understanding of the performance of the pulse generator 1 under various pressure conditions. The safety protection and sealing are good. The sealing plug 27 is threadedly connected to the top plate 13 and the gear box 25 to effectively prevent leakage and protect the control line of the pulse generator 1. In addition, the pressure gauge 29 and the sensor 21 provide real-time feedback of pressure changes to ensure that during the test process, there will be no equipment damage or safety hazards due to excessively high or low pressure.
