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: 11834928Abstract: A drill string rotation controller includes an anti-torque balance module, a TC bearing retaining ring, an upper TC bearing, an upper thrust ball bearing, an upper Haval ring, a middle seal retaining ring, an upper mandrel, an upper shell, a rotary control cylinder, an upper spring, a spline shell, a spline sleeve, a spline mandrel, a lower shell, a spring push sleeve, a lower spring, a floating piston, a lower mandrel, a bulkhead, a lower thrust ball bearing, a lower Haval ring, a lower TC bearing, a conversion joint, an anti-drop joint, a lower joint, and a control pin. The rotary control cylinder causes the spline sleeve to switch the transmission relationship between the spline mandrel and shell. Therefore, the drill string rotation controller controls the conversion between the composite drilling mode and the directional drilling mode.Type: GrantFiled: September 28, 2022Date of Patent: December 5, 2023Assignees: Southwest Petroleum University, Sichuan Xieming Technology Co., Ltd.Inventors: Jialin Tian, Haolin Song, Yinglin Yang, Yanniu Ren, Lin Yang, Zhe Zhang, Bo He, Jun Li, Yu Wei, Lei Cha

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: 10329849Abstract: The present invention relates to a multi-functional drilling experiment platform, which consists of a gantry, a hydraulic cylinder, a power swivel and a platform base. The gantry mainly realizes the control of the drill string during the drilling-in process. In order to simulate the vertical well, the inclined well, and the horizontal well, the drilling machine needs to rotate between 0° and 90°. The rotation of the gantry is realized by the extension and contraction of the hydraulic cylinder. The platform base is used to set up the gantry and the hydraulic cylinder, bearing the pulling, pressing and twisting loads of drilling experiments. Also, the platform base can move along the track to achieve different types of experiments. The multi-functional drilling experiment platform of the present invention realizes the load simulation experiment of the drilling machine at different angles using the gantry and the hydraulic cylinder.Type: GrantFiled: June 8, 2017Date of Patent: June 25, 2019Assignee: SOUTHWEST PETROLEUM UNIVERSITYInventors: Jialin Tian, Zhi Zhu, Ping Chen, Dejie Chen, Yanniu Ren, Qiang Wang
