Description

Technical Field

[0001] The present invention belongs to the technical field of pulser detection, and in particular, relates to a pulser testing device and a pulser testing method. Background Art

[0002] A pulser is a device for transmitting signals. It generates pulse signals by injecting liquid medium into the pipe and controlling the flow of the liquid medium in an orderly manner. The following is a brief description of the working process of the pulser: 1. Injecting liquid medium: First, the liquid medium is injected into the pipe, and the pressure pump provides pressure to drive the liquid medium to flow; 2. Control the flow of liquid medium: The pulser uses valves or other regulating devices to control the flow of liquid medium, and generates pulse signals by changing the flow rate and flow rate of the liquid medium; 3. Signal encoding: In liquid medium pulsers, mechanical or electrical devices are usually used to encode pulse signals. For example, pulse signals can be encoded by adjusting the opening and closing time of valves, or electrical sensors can be used to monitor the flow of liquid media and convert them into corresponding pulse signals; 4. Signal transmission: The pulse signal is transmitted to the receiving device on the ground through the pipe along with the flow of liquid medium. The receiving device usually uses pressure sensors or other sensors to detect and decode the pulse signal; 5. Decoding and analysis: The receiving device on the ground decodes and analyzes the received pulse signal to obtain relevant instrument parameters.

[0003] In general, the pulser uses the flow characteristics of the liquid medium to generate pulse signals in the pipe, and these signals are decoded and analyzed by the receiving equipment on the ground to monitor and control the connected instruments.

[0004] The existing pulser test scheme is to simulate the normal working state of the instrument to complete the pulser test, that is, the instrument, pulser, and pressure pump are connected together through pipes, liquid medium is introduced to start the pulser, the pulse signal is detected by the pressure sensor, and finally the receiving device decodes and analyzes the pulse signal to obtain relevant instrument parameters.

[0005] However, the above-mentioned pulser testing scheme requires professional equipment to test the pulser. The cost of a complete set of large-scale fluid testing equipment is very high. In actual practice, the instrument is often transported to a place with corresponding equipment and rented for testing.

[0006] The existing testing method requires the pulser to be installed in a pipe and connected to a pump and other pipes, and the installation process is cumbersome, time-consuming and labor-intensive.

[0007] The pulse signal generated by the existing test method will be distorted due to factors such as the pump noise of the pressure pump in the test equipment, the liquid medium, and the sensor accuracy, making the pulse signal difficult to identify.

[0008] Furthermore, in existing testing methods, if a failure occurs during the test, it is impossible to locate the problem immediately and all the testing equipment must be disassembled again. Summary of the invention

[0009] In view of the technical problems mentioned above, the present invention aims to provide a pulser testing device, which can be separated from large-scale fluid testing equipment to perform pulser testing.

[0010] The present invention also proposes a pulser testing method, which can be used to perform pulser testing without using large-scale fluid testing equipment.

[0039] The present invention will be described below with reference to the accompanying drawings.

[0040] It should be noted that the directional terms or qualifiers "left", "right", etc. used in this application are all relative to the referenced Figure 1 They are not intended to define the absolute positions of the components involved, but may vary depending on the specific circumstances.

[0041] Figure 1 The structure of the pulser testing device 100 according to the present invention is shown. Figure 2 The working principle of the pulse generator test device 100 according to the present invention is shown. Figure 1 and Figure 2 As shown, the pulser testing device 100 includes a pulser module 1 , an instrument module 2 , an acquisition module 3 and a data processing module 4 .

[0042] The pulser module 1 is the pulser to be tested. In this embodiment, the pulser module 1 includes a main body 11 and a mushroom head 12 disposed on the main body, and the mushroom head 12 is configured to be able to generate displacement relative to the main body 11. In the actual working process of the pulser module 1, the displacement of the mushroom head 12 can generate a pulse signal.

[0043] The instrument module 2 is electrically connected to the pulser module 1, and the instrument module 2 can send data that needs to be converted into pulse signals to the pulser module 1. In the actual working process, the instrument module 2 generates data that needs to be converted into pulse signals according to the needs of the actual situation, and sends it to the pulser module 1. After the pulser module 1 receives the data from the instrument module 2, the main body 11 of the pulser module 1 converts it into the corresponding mushroom head 12 action instruction through coding, and then the mushroom head 12 is driven according to the action instruction to perform the corresponding displacement action.

[0044] In a specific embodiment, the instrument module 2 simulates the actual instrument to send data through the host computer software. In this way, the overall structure of the pulse generator test device 100 can be simplified.

[0045] It should be noted that the host computer software can adopt existing technology, which is not the technical point of the present invention and will not be described in detail here.

[0046] The acquisition module 3 is configured to generate an electrical signal in response to the displacement of the mushroom head 12. That is, the acquisition module 3 can monitor the displacement state of the mushroom head 12 in real time and convert the displacement of the mushroom head 12 into a corresponding electrical signal.

[0047] In a specific embodiment, the acquisition module 3 includes a sensor 31, which is fixedly connected to the main body 11, and the position where the sensor 31 is set corresponds to the mushroom head 12. Through this arrangement, during the displacement of the mushroom head 12 relative to the main body 11, the sensor 31 is fixed relative to the main body 11, so the mushroom head 12 is also displaced relative to the sensor 31, and the sensor 31 can detect the displacement state of the mushroom head 12 and generate a corresponding electrical signal.

[0048] According to the present invention, Figure 1 As shown, a fixing device 32 is provided on the outer wall of the main body 11 , and the sensor 31 is fixedly connected to the main body 11 via the fixing device 32 .

[0049] In a specific embodiment, the fixing device 32 includes a fixing sleeve 321 fixedly sleeved on the outer wall of the main body 11, the fixing sleeve 321 is arranged in an annular shape, and is coaxially sleeved on the main body 11. A fixing rod 322 is fixedly arranged on the fixing sleeve 321, one end of the fixing rod 322 is fixedly connected to the outer wall of the fixing sleeve 321, the fixing rod 322 is parallel to the central axis of the main body 11, the sensor 31 is fixed on the other end of the fixing rod 322, and the sensor 31 corresponds to the mushroom head 12.

[0050] In a specific embodiment, the main body 11 is set in a cylindrical shape, and the mushroom head 12 is located at the axial end of the main body 11. The mushroom head 12 can reciprocate along the direction of the central axis of the main body 11. The sensor 31 is set in the direction of the moving axis of the mushroom head 12. Figure 1 As shown, the sensor 31 is located on the side of the mushroom head 12 away from the main body 11, and there is a certain gap between the sensor 31 and the mushroom head 12, and the gap between the two is enough for the displacement of the mushroom head 12. When the mushroom head 12 moves relative to the main body 11, a relative displacement occurs between it and the sensor 31.

[0051] like Figure 2 As shown, the acquisition module 3 also includes a power supply 33 and a signal collector 34. The power supply 33 is electrically connected to the sensor 31 and the signal collector 34, and the power supply 33 supplies power to the sensor 31 and the signal collector 34. The signal collector 34 is electrically connected to the sensor 31 and the data processing module 4, and the signal collector 34 collects the electrical signal generated by the sensor 31 and transmits it to the data processing module 4. The sensor 31 generates a corresponding electrical signal according to the displacement state of the mushroom head 12, and then the sensor signal is transmitted to the signal collector 34, and the signal collector 34 converts the sensor signal into corresponding data, and then transmits the data to the data processing module 4.

[0052] In a specific embodiment, the data processing module 4 is configured as a PC terminal, in which corresponding data processing software is installed to process and analyze the data transmitted by the signal collector 34 .

[0053] It should be noted that the data processing software installed in the PC terminal is a prior art and is not the technical point of the present invention, and will not be described in detail here.

[0054] The PC end is electrically connected to the signal collector 34 of the collection module 3 , so that the PC end can receive the electrical signal generated by the signal collector 34 .

[0055] In one embodiment of the present invention, a pulser testing method is provided. The pulser testing device 100 provided according to the present invention is used for testing. The movement state of the mushroom head 12 of the pulser module 1 is directly detected, so that the structure of the pulser itself can be detected more directly.

[0056] In the pulser testing method provided by the present invention, the mushroom head 12 of the pulser module 1 and the sensor 31 form a proximity switch. The principle of the proximity switch is that a signal is generated when the mushroom head 12 approaches the sensor 31, and the signal disappears when it is away from the sensor 31. The action sequence of the pulser module 1 can be obtained by the generation and disappearance of the signal of the proximity switch.

[0057] The instrument module 2 is responsible for sending data that needs to be converted into pulse signals to the pulser module 1. The data that needs to be converted into pulse signals is usually obtained by actual measurement of the instrument module 2, but the upper computer software can also simulate the actual instrument sending data. Using the upper computer software to simulate the actual instrument sending data can reduce the volume of the pulser test device 100 of the present invention and simplify the operation process. The main body 11 of the pulser module 1 is responsible for converting the data sent by the instrument module 2 into the corresponding action instructions of the mushroom head 12 through internal coding and driving the mushroom head 12 to reciprocate linear motion. The signal collector 34 is responsible for collecting the signal generated by the sensor 31 and transmitting it to the data processing module 4. Among them, Figure 2 As shown, the instrument module 2 is connected to the pulser module 1 , the sensor 31 is connected to the signal collector 34 , and the sensor 31 and the signal collector 34 are simultaneously connected to the power supply 33 , and the output port of the signal collector 34 is connected to the data processing module 4 .

[0058] like Figure 3 As shown, the following are the steps of the complete testing process:

[0059] 1. Instrument module 2 sends data to pulser module 1;

[0060] 2. After receiving the data, the pulser module 1 converts it into the corresponding mushroom head 12 action instruction through internal coding;

[0061] 3. The pulser module 1 drives the mushroom head 12 to perform reciprocating linear motion;

[0062] 4. The sensor 31 obtains a signal as the mushroom head 12 approaches or moves away;

[0063] 5. The sensor 31 transmits the signal to the signal collector 34;

[0064] 6. Finally, the signal collector transmits the received signal to the data processing module 4.

[0065] The pulser testing method in the prior art requires that the pulser module 1 be installed in a pipe and connected to other equipment such as a pump, and liquid medium be added to the pipe to fully simulate the actual working state of the pulser underground, and then the pulser is tested by detecting the pulse signal generated by the pulser in the liquid medium.

[0066] This testing method in the prior art requires professional equipment to test the pulser. The cost of a complete set of equipment is very high. The instrument is often transported to a place with corresponding equipment and rented for testing, which increases the cost of pulser testing. Moreover, this testing method requires the pulser to be installed in a pipe and connected to a pump and other pipes, and the installation process is cumbersome, time-consuming and labor-intensive.

[0067] In addition, the pulse signals generated by existing testing methods will be distorted due to factors such as pump noise, liquid medium, and sensor accuracy, making the pulse signals difficult to identify.

[0068] Furthermore, since the testing methods in the prior art use many devices, if a failure occurs during the test, it is impossible to locate the problem immediately and all the instruments need to be disassembled. The pulser is set inside the pipe and the movement state of the pulser cannot be directly observed, so it is impossible to determine whether the pulser is working properly.

[0069] The pulser test device 100 provided by the present invention saves costs, time and effort. The existing method of simulating the actual working state of the pulser is labor-intensive, arduous and costly. The present test device and method can complete functional testing in the workshop and is easy to install.

[0070] The signal obtained by the pulse generator testing device 100 provided by the present invention is basically free of other interference factors, and the signal is clean, which is convenient for verifying whether the data is correct.

[0071] The pulser testing device 100 provided by the present invention does not install the pulser inside the pipe, so the actual working condition of the pulser can be observed intuitively to determine whether the mechanical structure has problems such as jamming.
