Publication number: 20240044237Abstract: A method of a shale gas reservoir stimulation by oxidation-induced rock burst includes performing a hydraulic fracturing stimulation on a shale gas well to be fractured; during the hydraulic fracturing, successively pumping slick water A, oxidizing fluid, glue liquid-containing slick water, catalytic decomposition fluid, and slick water B in a form of liquid slug. In the present invention, methane released by fracturing by the slick water A is mixed with oxygen generated by decomposition of hydrogen peroxide in the oxidizing fluid to induce oxidation-induced rock burst. Based on the physical properties and chemical thermodynamic properties of shale, a calculation method for the amount of fracturing fluid used and the radius of oxidation-induced rock burst is proposed, thereby realizing safe, efficient, and non-destructive multi-scale stimulation of hydraulic fractures-burst fractures-dissolution pores and fractures.Type: ApplicationFiled: November 24, 2021Publication date: February 8, 2024Applicant: Southwestern Petroleum UniversityInventors: Lijun YOU, Rui QIAN, Qiuyang CHENG, Yili KANG, Nan ZHANG, Yang ZHOU, Yang CHEN, Furong WANG, Daoquan FAN

Patent number: 11105261Abstract: Detecting manipulation of an SCR catalytic converter system of a motor vehicle. A control command (61) for the SCR catalytic converter system, transmitted from a control unit outside the motor vehicle, is received by the motor vehicle. Manipulation is detected (57) if a response (55) of the SCR catalytic converter system to the execution (54) of the control command (61) does not correspond to expectation. Embodiments also relate to monitoring manipulation of the SCR catalytic converter system. Here, a control command (61) for the SCR catalytic converter system is transmitted (41) to the motor vehicle (10) from a control unit (20) outside the motor vehicle.Type: GrantFiled: September 26, 2019Date of Patent: August 31, 2021Assignee: ROBERT BOSCH GMBHInventors: Peter Huebner, Rui Qian
