Publication number: 20240094699Abstract: A height measurement method, quality compensation method, and height measurement system based on a height measurement assembly of a numerical control apparatus. The height measurement method includes driving the height measurement assembly to move on a coordinate axis of the numerical control apparatus through a preset positioning mechanism on a plane to be measured of an assembly to be measured, so as to obtain a preset movement distance corresponding to each movement; acquiring reflected light patterns of several planes to be measured through a photoelectric signal collection array in each movement process, and acquiring a distance between adjacent reflected light patterns through a processing portion; and acquiring a target height of the assembly to be measured through a preset height acquisition model according to each preset movement distance and the distance between adjacent reflected light patterns corresponding to each preset movement distance.Type: ApplicationFiled: April 4, 2023Publication date: March 21, 2024Inventor: Tianrun CHEN

Patent number: 10712466Abstract: Systems, methods, and software for determining a thickness of a well casing are described. In some aspects, the thickness of the well casing is determined based on results of comparing a measured waveform and model waveforms. The measured waveform and model waveforms are generated based on operating an acoustic transmitter and an acoustic receiver within a wellbore comprising the well casing.Type: GrantFiled: July 15, 2014Date of Patent: July 14, 2020Assignee: Halliburton Energy Services, Inc.Inventors: Tianrun Chen, Yibing Zheng, Tatiana Gilstrap, Arthur Chuen Hon Cheng, Robert Eric Epstein

Patent number: 10301932Abstract: Systems, methods, and software for determining impedance of a casing-cement bond are described. In some aspects, the bond impedance is determined based on results of comparing a measured waveform and a model waveform. The model waveform corresponds to an estimated impedance of the bond and corresponds to a ray tracing of an acoustic signal that accounts for a radiation pattern of the acoustic transmitter and a curvature of the well casing. The measured waveform and the model waveform are generated based on operating an acoustic transmitter and an acoustic receiver within a wellbore comprising the well casing.Type: GrantFiled: July 15, 2014Date of Patent: May 28, 2019Assignee: Halliburton Energy Services, Inc.Inventors: Tianrun Chen, Yibing Zheng, Tatiana Gilstrap, Arthur Chuen Hon Cheng, Robert Eric Epstein, Zhijuan Zhang

Patent number: 10202846Abstract: A downhole telemetry well system transmits data at a high rate inside a tubular pipe by encoding signals on a Stoneley wave. Telemetry devices for the Stoneley mode are implemented in short pipe joints inserted at various intervals between the tubulars. Each telemetry device includes Stoneley transducers, which may act as a transmitter, receiver, or repeater. The Stoneley telemetry devices transmit and receive the Stoneley waves making up the carrier of the signal. The Stoneley telemetry devices may be powered by on-board batteries or via some remote power source.Type: GrantFiled: February 10, 2015Date of Patent: February 12, 2019Assignee: Halliburton Energy Services, Inc.Inventors: Roland E. Chemali, Ronald Dirksen, Paul F. Rodney, Arthur C. H. Cheng, Tianrun Chen

Patent number: 9952344Abstract: A disclosed high-purity dipole transmitter has a longitudinal axis, an oscillation axis, and a side axis, each of the axes being mutually orthogonal. The transmitter includes an outer shell having external surfaces for displacing fluid along the oscillation axis. The transmitter also includes a reaction mass positioned inside the outer shell. The transmitter also includes an electromagnetic actuator that drives the outer shell relative to the reaction mass. The transmitter also includes a pair of matching springs separated along the longitudinal axis, where each spring is coupled between the outer shell and the reaction mass to enable compliant dipole motion of the outer shell along the oscillation axis while suppressing motion along other axes. Each spring includes a beam arrangement with each beam extending lengthwise in a direction parallel to the side axis and being thinnest in a direction parallel to the oscillation axis.Type: GrantFiled: February 27, 2014Date of Patent: April 24, 2018Assignee: Halliburton Energy Services, Inc.Inventors: Chung Chang, Tianrun Chen, Gary Kainer, Haoshi Song

Patent number: 8982671Abstract: The present disclosure provides embodiments seismic energy sources configured to generate enhanced shear wave energy in order to more accurately determine the distribution and orientation of fractures in subterranean formations. At least one seismic energy source includes an elongate rod having a first end and a second end, a detonator coupled to the first end, and a bull plug coupled to the second end. An explosive is helically-wrapped about the elongate rod continuously from the first end to the second end and configured to detonate such that a time-delayed detonation is achieved which induces increased shear wave energy in the surrounding formations.Type: GrantFiled: April 23, 2012Date of Patent: March 17, 2015Assignee: Halliburton Energy Services, Inc.Inventors: Mark Elliott Willis, Erkan Ay, Norm Warpinski, Tianrun Chen
