Description

Technical Field

[0001] This invention relates to the field of acid fracturing ball launcher technology, and more particularly to a remote control device for fracturing ball launcher equipment. Background Technology

[0002] In recent years, the multi-stage fracturing process for horizontal wells has become increasingly complex, characterized by large-scale fracturing operations, high wellhead pressure, and the need for multiple pump shutdowns during the fracturing process. Therefore, it requires large inner diameters for the fracturing wellhead and its supporting equipment to meet the requirements of large-volume fracturing and large-size tools, as well as to be able to seal under high pressure, have high safety and reliability, and be easy to operate.

[0003] Existing remote control devices for fracturing ball-dropping equipment mainly use hydraulic ball-dropping. Construction personnel need to enter the high-pressure fracturing zone to drop fracturing balls into the device. The high wellhead pressure during the construction process seriously threatens the safety of operators. At the same time, it is impossible to accurately count the number of balls dropped, and it is also impossible to integrate with other equipment for control or achieve remote data transmission and sharing.

[0004] Addressing the issues of high wellhead pressure during fracturing operations, which seriously threaten operator safety, the inability to accurately count the number of balls thrown, and the lack of integration with other equipment for control or data sharing, this new remote control device for fracturing ball-throwing equipment combines remote wireless ball loading and remote wired ball throwing. This enables remote ball loading and throwing operations at the wellhead, preventing personnel from entering the high-pressure zone and ensuring their safety. It also automatically and accurately throws and counts balls, integrates the ball-throwing device with field equipment for centralized control, and can transmit field ball-throwing data to a remote terminal for remote expert command. The system boasts a fast response time and a high degree of automation and intelligence. Summary of the Invention

[0005] To overcome the limitations of existing remote control devices for fracturing ball-dropping equipment, which mainly use hydraulic ball-dropping, operators need to enter the high-pressure fracturing zone to drop fracturing balls into the device.

[0028] Preferably, remote startup and monitoring include the following steps: S41: On the portable remote control box 1, click the "Start" button to send a start command to the PLC controller 6; S42: Through the touch screen 8 interface of the portable remote control box 1, the operating status, number of balls thrown, and key parameters of the motor speed of the servo motor 13 can be monitored in real time; S43: If any abnormality is found, immediately stop the equipment operation and conduct troubleshooting and handling.

[0029] Preferably, the following steps are included when performing a pitching operation: S51: PLC controller 6 controls servo motor 13 to drive transmission mechanism according to preset parameters, so as to load the temporary blocking ball into the ball throwing tube; S52: When the conditions for ball throwing are met, the PLC controller 6 controls the servo motor 13 to run at the set speed and direction, and throws the temporary plugging ball into the fracturing tubing through the spiral shaft 20; S53: After the ball is thrown or when it is necessary to return the ball, the PLC controller 6 controls the servo motor 13 to run in reverse to return the remaining temporarily blocked ball to the initial position.

[0030] Preferably, when recording data after the job is completed, the following steps are included: S61: On the portable remote control box 1, click the "Stop" button to end the throwing operation; S62: Export, save, and analyze relevant data from the throwing operation via the portable remote control box 1 or PLC controller 6; S63: Perform necessary cleaning and maintenance on the ball-throwing equipment and portable remote control box 1 to ensure that the equipment is in good condition and ready for the next operation.

[0031] Before starting the operation, first select the control mode by switching the switch on the physical operation panel of the portable remote control box 1. The following describes the two operation modes: remote wireless ball loading and remote wired ball throwing.

[0032] Remote wireless ball loading control process: When the mode switch is in "remote control", the system is remotely controlled by the handheld remote control 2, and the portable remote control box 1 is ineffective at this time.

[0033] In the "remote control" mode, the settings parameters need to be initialized first. Open the parameter setting interface of the touch screen 8, input the maximum allowable number of temporary blocking balls according to the specifications of the spiral shaft 20, then turn the speed switch knob of the handheld remote control 2 from "low speed / medium speed / high speed" to "low speed", turn the direction switching knob from "forward / reverse" to "forward", press the "manual control" button, the servo motor 13 will run and start loading balls, release the "manual control" button, the servo motor 13 will stop, and the ball loading operation can be completed by jogging the servo motor 13.

[0034] Remote wired ball throwing control process: When the mode switch is in "control box", the system is remotely controlled by the portable remote control box 1, and the handheld remote controller 2 is ineffective at this time.

[0035] In the "control box" control mode, the settings parameters need to be initialized first. Open the main interface of the touch screen 8, set the two parameters "number of balls installed" and "number of balls to be thrown", turn the "manual / automatic" switch knob of the portable remote control box 1 to the "automatic" position, turn the "forward / reverse" switch knob to the "forward" position, press the "start throwing" button, the servo motor 13 runs, and the system automatically stops throwing after completing the number of balls thrown according to the program settings. During the entire throwing process, press the "stop throwing" button to stop the servo motor 13 and stop the throwing operation. Throwing can also be done in manual mode. Turn the "manual / automatic" switch knob of the portable remote control box 1 to the "manual" position, press the "start throwing" button, and start throwing.

[0036] After the throwing operation is completed, if there are any extra balls that need to be ejected, turn the "forward / reverse" switch knob on the portable remote control box 1 to the "reverse" position. The servo motor 13 will run and will not count during reverse rotation, thus completing the ball ejection operation.

[0037] The encoder body 12 detects the rotation angle and direction of the servo motor 13 in real time, converts these signals into digital signals through the servo driver 7, and then feeds them back to the PLC controller 6. The PLC controller 6 obtains the "number of balls thrown" and "total number of balls thrown" according to the counting program, and displays the "number of balls thrown" and "total number of balls thrown" on the main interface of the touch screen 8, so that the on-site operators can record, view and export the data.

[0038] Ball throwing count process: When the system is running, the PLC controller 6 calculates how many revolutions the servo motor 13 spindle needs to rotate according to the set "number of balls to be thrown". The servo motor 13 starts rotating according to the calculated number of revolutions. The servo motor 13 spindle counts 6 times for each revolution, that is, the number of balls thrown Q = 6 * (C / P) * n (where Q is the number of balls thrown; C is the total number of pulses at the current position; P is the number of pulses required for the servo motor 13 to rotate once; n is the reduction ratio of the reducer driven by the servo motor 13). When the calculated number of revolutions is reached, it stops automatically. The PLC controller 6 and the servo driver 7 control the ball throwing device to automatically complete the preset number of balls thrown.

[0039] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
