Publication number: 20220094255Abstract: The present invention provides an annular linear induction electromagnetic pump having axial guide vanes, wherein m axial guide vanes are uniformly arranged in a flow channel of the electromagnetic pump in a circumferential direction, a magnitude of m is equal to a number of external stators, and a length of each of the guide vanes is determined together by the number of the external stators, a central radius of the flow channel, a magnetic Reynolds number, and a wave number of a traveling magnetic field. The axial guide vanes can significantly mitigate the impact on the flow field stability caused by uneven circumferential disturbances of the magnetic field and flow field, thereby achieving a flow stabilization effect and greatly improving the flow stability in operation under off-design conditions.Type: ApplicationFiled: January 7, 2021Publication date: March 24, 2022Applicant: JIANGSU UNIVERSITYInventors: Ruijie ZHAO, Xiaohui DOU, Qiang PAN, Desheng ZHANG

Patent number: 11283342Abstract: An annular linear induction electromagnetic pump having axial guide vanes is provided. m axial guide vanes are uniformly arranged in a flow channel of the electromagnetic pump in a circumferential direction, and a magnitude of m is equal to a number of external stators. A length of each of the guide vanes is precisely determined by a parameter P, and the value of the parameter P is calculated together by the number of the external stators, a central radius of the flow channel, a magnetic Reynolds number, a wave number of a traveling magnetic field and the mean fluid velocity. The axial guide vanes can significantly mitigate the impact on the flow field stability caused by uneven circumferential disturbances of the magnetic field and flow field, thereby achieving a flow stabilization effect with less hydraulic losses and greatly improving the flow stability in operation under off-design conditions.Type: GrantFiled: January 7, 2021Date of Patent: March 22, 2022Assignee: JIANGSU UNIVERSITYInventors: Ruijie Zhao, Xiaohui Dou, Qiang Pan, Desheng Zhang

Patent number: 9766362Abstract: A system and a method use dual telemetry for tools located in a wellbore. A first telemetry system and a second telemetry system coordinate communication with the tools. Both the first telemetry system and the second telemetry system may transmit data regarding the tools and/or drilling conditions from the tools to a surface location simultaneously. The first telemetry system or the second telemetry system may communicate with the surface location if communication using the other telemetry system is interrupted. The first telemetry system and the second telemetry system may have a master/slave relationship so that data requests from a specific telemetry system do not interfere with data requests from the other telemetry system.Type: GrantFiled: August 20, 2013Date of Patent: September 19, 2017Assignee: Schlumberger Technology CorporationInventors: Qiming Li, Desheng Zhang, Yi Zhang, Lili Zhong, Xueyuan Tang, Brian Oliver Clark

Patent number: 8866633Abstract: The present disclosure relates to a method to determine a clock signal when separate clocks are used. In one embodiment, a disciplined clock system comprising an update subsystem and a synthesis subsystem is provided. A first clock phase estimate is provided to the update subsystem and used, along with the update subsystem, to determine a frequency offset estimate and a phase offset estimate. The clock signal is determining using the frequency offset estimate, the phase offset estimate, and the synthesis subsystem. Alternatively, two clocks can be synchronized by generating a signal associated with a first clock; modulating the signal; transmitting the modulated signal; receiving the modulated signal by a receiver associated with a second clock; correlating the received signal; determining the time of arrival of the received signal; determining the time difference between the two clocks; and synchronizing the two clocks.Type: GrantFiled: May 8, 2013Date of Patent: October 21, 2014Assignee: Schlumberger Technology CorporationInventors: Michael Montgomery, Julius Kusuma, Jean Seydoux, Desheng Zhang
