Patent number: 11754535Abstract: An ultrasonic in-situ automatic detection system for creep cracks on an inner wall of a hydrogen production furnace tube. The system comprises a computer, a multi-channel ultrasonic system control circuit, a motor driver board, a coreless motor, and a tube crawling machine. Multi-channel piezoelectric transducers are arranged in a circumferential direction of the furnace tube. The computer is configured to send detection instructions to the multi-channel ultrasonic system control circuit through a wireless network; the multi-channel ultrasonic system control circuit is configured to control multiple channels to simultaneously excite the piezoelectric transducers, receive echo signals from the piezoelectric transducers and then send the echo signals back to the computer in a wireless mode; and the motor driver board is configured to drive the coreless motor to drive the tube crawling machine to move, receive motion parameters fed back by motor encoders, and send the motion parameters back to the computer.Type: GrantFiled: July 29, 2021Date of Patent: September 12, 2023Assignees: China Special Equipment Inspection and Research Institute, Beijing University of TechnologyInventors: Luowei Cao, Zhongtian Lyu, Yan Lyu, Cunfu He, Guorong Song, Zhiyuan Han

Patent number: 11603720Abstract: The present disclosure provides a method for running a drilling rig or a workover rig including a plurality of stands into a wellbore. In step 1, position information of the stands in a finger board area may be recorded with a control system. In step 2, the stands may be placed. In step 3, a position of a traveling block may be adjusted so as to move a power elevator to a second waiting position of a racking platform. In step 4, the stands may be pushed with the pipe racking device. In step 5, the second stand may be moved and stabbed in the first stand with an iron floor man. In step 6, a joint between the first stand and the second stand may be made up. In step 7, the traveling block may be moved downward. In step 8, the traveling block may be moved upward.Type: GrantFiled: July 21, 2021Date of Patent: March 14, 2023Assignee: SICHUAN HONGHUA PETROLEUM EQUIPMENT CO., LTD.Inventors: Junqing Chai, Yan Lyu, Liangliang Liang, Aimin Tang, Zhenghua Wu

Patent number: 11299942Abstract: The present disclosure discloses a drilling machine. The drilling machine may include a base, a mast arranged on the base, an iron roughneck, a drill floor mechanical arm, a top drive arranged on the mast, a pipe racker on a finger board, a power finger board, a power catwalk arranged on the ground, and an elevator arranged on the top drive. The drill machine and a corresponding tripping out and tripping in method may be used to vertically transport a stand between a well center and a region of at least one pipe setback efficiently, which may improve the efficiency of tripping out and tripping in, and reduce the risk of accidents in the well. In addition, the present disclosure provides a corresponding method for offline connecting and disconnecting stands during a drilling operation, which may reduce a preparation time during the drilling, improve the drilling efficiency, and reduce the cost of oilfield development.Type: GrantFiled: July 16, 2021Date of Patent: April 12, 2022Assignee: SICHUAN HONGHUA PETROLEUM EQUIPMENT CO., LTD.Inventors: Chong Chen, Yu Tian, Aimin Tang, Hang Gao, Zhigang Li, Yan Lyu, Bo He, Xiaohu Li

Patent number: 11286731Abstract: A pipe racking system includes a diving board having a guide rail, a trolley, a manipulator, and a gripper. The trolley has two sides being mounted to the diving board via the guide rail and being driven by a rack and pinion member. The gripper is connected to an end of the manipulator away from the trolley. The trolley includes two pairs of combined bearings and two pairs of eccentric wheels. The gripper is configured to grip a tubular subject and include two opposing flippers, two first electric putters, and two springs. The two first electric putters is configured to control the two flippers. One end of each spring of the two springs is connected to a flipper of the two flippers and the other end of the each spring is connected to a push rod of a first electric putter of the two first electric putters.Type: GrantFiled: September 1, 2021Date of Patent: March 29, 2022Assignee: SICHUAN HONGHUA PETROLEUM EQUIPMENT CO., LTD.Inventors: Ying Li, Xiaohu Li, Lin Wang, Xiaowu Ou, Aimin Tang, Qionghua Yang, Junqing Chai, Yan Lyu
