Patent number: 12180808Abstract: The disclosure concerns oil drilling technology, and specifically an all-metal intelligent control motor (AMIM). The AMIM comprises an electric control module, a power module and a transmission module. The electric control module determines the axial position of the connecting rod valve through an electromagnet and controls the connection between the connecting rod valve and the piston through an electric motor. The hydraulic pressure of drilling fluid and the spring reaction force in the power module push a double worm to move axially and circumferentially under the action of internal teeth on the inner surface of shell. A one-way bearing ensures that the power module only transmits unidirectional motion. The transmission module axially limits the power module through TC bearings and transmits circumferential motion, drilling pressure and torque to the lower drilling tool. The AMIM is suitable for all kinds of deep well exploration, with a stronger drilling force, a lower cost and a higher applicability.Type: GrantFiled: June 20, 2023Date of Patent: December 31, 2024Assignees: Southwest Petroleum University, Nantong Xieming Technology Co., Ltd., Sichuan Xieming Technology Co., Ltd.Inventors: Jialin Tian, Junyang Song, Lei Cha, Heng Li, Yanniu Ren, Chunyu Xing, Lin Yang, Long Ran

Patent number: 11927077Abstract: A high-frequency composite impactor including a high-frequency axial and a torsional impact assembly is disclosed. The high-frequency axial impact assembly includes an upper self-excited oscillation cavity, a lower self-excited oscillation cavity, an adjustment block and a lock nut. The torsional impact assembly includes an upper end cover, a reversing switch, a pendulum, a lower shell, a lower end cover, a nozzle, a connecting block and a retaining ring. The high-frequency axial impact assembly converts the flowing drilling fluid into a pulsed jet to achieve a high-frequency axial impact. The torsional impact assembly enables a torsional impact through a shunt, and finally enables a high-frequency composite impact, which can effectively reduce the stick-slip of the drill string, jump drilling and other downhole accidents. By reducing the friction between the drill string and the borehole wall, the impactor can reduce WOB loss, increase the ROP, and improve the drilling efficiency.Type: GrantFiled: September 26, 2022Date of Patent: March 12, 2024Assignees: Southwest Petroleum University, Sichuan Xieming Technology Co., Ltd.Inventors: Jialin Tian, Lanhui Mao, Yanniu Ren, Lin Yang, Haolin Song, Bo He, Jun Li, Lei Cha, Zhe Zhang, Yu Wei

Patent number: 11828149Abstract: An oil and gas fracturing tool is disclosed, mainly involving a fracking tool with an electromagnetic intelligent control sliding sleeve including an outer sleeve section, a dart body section and a control section. The outer sleeve section is at the target location to be fractured. The effect of fracturing is mainly achieved by the dart body, which has an activated state and an inactive state. The initial state is inactive, and the front locking tip can be deformed under pressure during displacement. The diameter can change to pass through any sliding sleeve. When the dart body is counted and is about to reach the fracturing position, the front locking tip is blocked from deformation and cannot be reduced in diameter, thus pressurizing to control the fracturing effect. The control part includes a sensor module, a drive module, a main control module and a power supply module.Type: GrantFiled: January 16, 2023Date of Patent: November 28, 2023Assignees: Southwest Petroleum University, Nantong Xieming Technology Co., Ltd., Sichuan Xieming Technology Co., Ltd.Inventors: Jialin Tian, Yu Wei, Lanhui Mao, Yanniu Ren, Chunyu Xing, Junyang Song, Lei Cha, Lin Yang

Patent number: 11788407Abstract: The disclosure relates to petroleum drilling, specifically a downhole signal receiving and transmitting device. The downhole signal receiving and transmitting device includes a receiving part, a control device, a mechanical assembly and a transmitting mechanism. The receiving part receives a signal transmitted by a lower end instrument, and the control device process the received signal, controls a motor to drive a rotating sleeve, and the mechanical assembly performs work. The mechanical assembly drives a mandrel to rotate a rotor continuously and regularly. When rotating, the flow area of the rotor and a stator changes to produce continuous pulses. The pressure waveform changes are monitored on the ground, and the measurement data are calculated by decoding.Type: GrantFiled: June 11, 2021Date of Patent: October 17, 2023Assignees: Southwest Petroleum University, Sichuan Xieming Technology Co, Ltd.Inventors: Jialin Tian, Changqing Xiong, Lei Tang, Haolin Song, Lanhui Mao, Lin Yang
