Description

Technical Field

[0001] This application relates to the field of oil and water well operations, and in particular to a pumping data acquisition and safety warning device. Background Technology

[0002] In oil and water well testing operations, pumping is widely used in determining formation fluid properties, production volume, and for forced acid removal. Currently, during oil and water well pumping operations, a well cleaning rig, a set of ground pulleys, and a set of top pulleys work together to lower the steel wire rope wound on the well cleaning drum, carrying the pumping equipment into the well, and bringing the fluid from the wellbore to the surface.

[0003] During pumping operations, the pumping depth is determined solely by the driller's observation of the number of turns and layers of wire rope on the well cleaning rig drum. Initially, the wire rope on the well cleaning rig drum is relatively neatly arranged, allowing for a fairly accurate estimation of the pumping depth. However, as the number of pumping operations increases, the wire rope becomes disorganized, or parts of the wire rope are cut due to twisting, leading to significant errors. Furthermore, the calculation of the number of pumping operations relies solely on the operator's memory, which can easily result in omissions or over-recording. Therefore, traditional pumping operations suffer from significant data errors. During pumping, the pumping signal rope is a crucial safety device; the driller uses the position of the signal rope to promptly slow down and stop the operation.

[0004] Currently, the pumping signal rope is mainly made by weaving colored nylon rope into a twisted pumping steel wire rope and setting it sequentially at designated positions. This method results in the signal rope wearing down during pumping and requires frequent replacement. Furthermore, during nighttime pumping operations, operators have difficulty observing the signal rope, increasing the risk of accidents where the pumping device strikes the wellhead. Utility Model Content

[0006] The technical solution of this application is:

[0007] A data acquisition and safety warning device for pumping out pumps includes a signal acquisition mechanism and a signal processing mechanism. The signal acquisition mechanism includes a magnetic transmitter, a Hall sensor, and a mounting base.

[0030] Example:

[0031] Please refer to Figure 1(Refer to) Figures 2 to 3 This application provides a data acquisition and safety warning device for well drilling, including a signal acquisition mechanism and a signal processing mechanism. The signal acquisition mechanism includes a magnetic transmitter 1, a Hall sensor 2, and a mounting base 3. The signal processing mechanism includes a signal processor 8 and an audible and visual alarm 9, both installed in the driller's operating room of the well cleaning machine 7. The magnetic transmitter 1 is installed on one side of the pulley 5 of the derrick 4 and is used to convert the rotation direction and number of rotations of the pulley 5 into a magnetic signal and send it to the Hall sensor 2. This conversion process uses existing technology, and its specific working principle will not be described here. At the same time, the mounting base 3 is installed on a fixed bracket 6 for supporting the pulley 5, and a positioning hole is opened on the end away from the fixed bracket 6, facing the magnetic transmitter 1. In addition, one end of the Hall sensor 2 is connected to the positioning hole and faces the magnetic transmitter 1, and the other end is electrically connected to the signal processor 8 through a signal transmission cable 10, for acquiring the received signals of the rotation direction and number of rotations of the pulley 5. This acquisition process uses existing technology, and its specific working principle will not be described here. Meanwhile, its signal processor 8 is connected to the Hall sensor 2 via a signal transmission cable 10, used to convert the rotation direction and number of rotations of the ground pulley 5 into the pumping depth. This conversion process uses existing technology, and its specific working principle will not be elaborated here. The audible and visual alarm 9 is connected to the signal processor 8 via the signal transmission cable 10, used to issue a warning signal when the pumping depth reaches the alarm setting value. In addition, its derrick 4 is installed on the well workover vehicle 13, and the derrick 4 is connected to the well cleaning machine 7 via a pumping wire rope 14. The pumping wire rope 14 is connected to the ground pulley 5 and the top pulley 15 in sequence from bottom to top. This device can collect more accurate data for pumping operations, provide more obvious warning signals for pumping operations, and ensure the accuracy of pumping data and operational safety.

[0032] It should be noted that in this embodiment, the magnetic transmitter 1 and the Hall sensor 2 are on the same straight line. Furthermore, the mounting base 3 is perpendicularly connected to the Hall sensor 2. In addition, the mounting base 3, the Hall sensor 2, and the magnetic transmitter 1 are all located on the same side of the pulley 5.

[0033] It should be noted that the Hall sensor 2 is a Hall sensing element, mainly used to detect the magnetic signal generated by the magnetic transmitter 1. The magnetic transmitter 1 is fixed to the side of the rotating pulley 5. The mounting base 3 is fixed to the fixed bracket 6 of the pulley 5, mainly used to fix the Hall sensor 2 and ensure that the Hall sensor 2 and the magnetic transmitter 1 are in the correct relative position. The signal transmission cable 10 is a four-core cable, mainly used to transmit the signal data returned by the Hall sensor 2, and also to provide power to the Hall sensor 2. As the pulley 5 rotates, the signal of the magnetic transmitter 1 is collected once every time it passes the fixed Hall sensor 2, that is, one rotation of the pulley 5 counts once.

[0034] It should be noted that the signal transmission cable 10 can be a four-core cable.

[0035] It should be noted that the signal processing mechanism also includes a pumping count display 11 and a pumping depth display 12, which are respectively installed on the driller's cab of the well dredging machine 7; wherein, the pumping count display 11 and the pumping depth display 12 are electrically connected to the signal processor 8, the pumping count display 11 is used to count and display the number of rotations of the pulley 5, and the pumping depth display 12 is used to record and display the current pumping depth.

[0036] It should be noted that in this embodiment, the magnetic transmitter 1, Hall sensor 2, signal transmission cable 10, audible and visual alarm 9, signal processor 8, pumping count display 11, and pumping depth display 12 all adopt existing structures, and their specific structures and working principles will not be described in detail here. Furthermore, the calculation of the number of rotations of the pulley 5 and the pumping depth by the signal processor 8 uses conventional existing technology, and the specific processing and calculation procedures will not be described in detail here.

[0037] It should be noted that the sampling count display 11 uses a sampling count device from the prior art, which mainly records one sampling cycle as one round trip over a distance of 30 to 500 meters, collected by the Hall sensor 2. The sampling depth display 12 mainly converts the signal collected by the Hall sensor 2 into the current sampling depth for display, providing the operator with intuitive values. The audible and visual alarm 9 is a buzzer and flashing red light alarm. When the sampling depth calculated by the signal processor 8 reaches the alarm setting value, the audible and visual alarm 9 immediately sounds a buzzer and flashes a light.

[0038] During the pumping operation, the pumping wire rope 14 drives the pulley 5 to rotate. The Hall sensor 2 installed on the pulley 5 converts the mechanical rotation direction and number of rotations into corresponding electrical signals, which are transmitted to the signal processor 8 in the well cleaning machine 7 cab via signal transmission cable. The pumping count display 11, connected to the signal processor 8, counts the number of rotations of the pulley 5 based on the received electrical signals, and simultaneously determines whether to increment or decrement the count based on the rotation direction. This conversion and calculation process uses existing technology, and its specific working principle will not be elaborated here. The running distance is calculated by multiplying the count value by the circumference of the pulley 5, and the pumping depth is accurately reflected by the pumping depth display 12. This conversion and calculation process uses existing technology, and its specific working principle will not be elaborated here. The audible and visual alarm 9 sets a warning point 30 meters away from the wellhead. When the depth of the pump is equal to or less than 30 meters, the alarm signal is triggered by the audible and visual alarm 9. The number of pumping operations is mainly calculated by identifying the pumping depth signal. When the pump passes through depth points of 30 meters and 500 meters, the pumping display 11 can record one pumping operation. Therefore, this device mainly reads the number of rotations of the pulley 5, processes it into pumping depth data through the signal processor 8, and sets alarm signal values ​​based on the depth data to provide early warning when the pump reaches the wellhead.

[0039] In summary, this device, by mounting the magnetic transmitter 1 and Hall effect sensor 2 on the pulley 5 on the derrick 4, allows the pulley 5 to rotate during pumping operations. The pulley 5 is driven by the pumping wire rope 14, and the Hall effect sensor 2, mounted on the pulley 5, converts the mechanical rotation direction and number of rotations into corresponding electrical signals, which are then transmitted to the signal processor 8. This signal is used to record the received rotation direction and number of rotations of the pulley 5. After reading the number of rotations of the pulley 5, the signal processor 8 processes this data into pumping depth data. Simultaneously, the depth data is used to set alarm signal values, providing early warning when the pump reaches the wellhead. Therefore, it can record more accurate data for pumping operations, ensuring data accuracy and operational safety.

[0040] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
