Patent number: 12122008Abstract: The invention relates to the field of milling, specifically a point position layout optimization method and a follow-up support head in mirror milling. It features an annular and linear sliding module to design a support head with adjustable support points. A corresponding layout optimization method is developed, starting with a coupled vibration model of the machining process. A layout optimization model is then created, with the quantity of support points and the support radius as decision variables. The goal is to minimize vibration amplitude and root mean square, constrained by structural interference and boundary conditions. The solution is achieved using a particle swarm optimization algorithm, supplemented by parameter scanning and a penalty function strategy. This invention addresses the limitations of existing single support point layouts for the mirror milling of various large thin-walled workpieces.Type: GrantFiled: May 30, 2024Date of Patent: October 22, 2024Assignee: HEFEI UNIVERSITY OF TECHNOLOGYInventors: Fangfang Dong, Zhao Liu, Xiaomin Zhao, Jiang Han, Xiaoyong Huang

Patent number: 11585212Abstract: A DAS VSP technique is used to determine the induced fracture height and fracture density of an induced fracture region. The DAS VSP technique obtains pre-hydraulic fracturing DAS VSP survey time-lapse data to establish a baseline reference for the direct acoustic wave travel time. The DAS VSP technique obtains one or more time-lapse data corresponding to the subsequent monitor surveys conducted after each hydraulic fracturing stage along the well. Forward modeling is used to determine a theoretical acoustic wave travel time difference. The forward modeling uses seismic anisotropy to describe the behavior of seismic waves traveling through the induced fracture regions. An inversion scheme is then used to invert for the induced fracture height and the fracture density using the forward modeling. The two extracted induced fracture characteristics may then be used to determine optimal hydraulic fracturing parameters.Type: GrantFiled: August 3, 2020Date of Patent: February 21, 2023Assignee: Halliburton Energy Services, Inc.Inventors: Xiaomin Zhao, Mark Elliott Willis

Patent number: 11340371Abstract: To mitigate zigzag noise and increase the quality of data provided from DAS VSP in wells with significant vertical sections, zigzag noise characteristics are identified and quantified. The zigzag noise properties can be extracted from an analysis of an autocorrelation of DAS VSP traces. The zigzag noise has a characteristic time period or repeat time delay that is the time period for the noise to propagate along the wireline through a zone of the wellbore with poor acoustic coupling between the fiber optic cable and formation. This period can be identified from analysis of the autocorrelation referred to herein as a crosswise lag summation function. The crosswise lag summation function identifies groups of DAS data traces containing zigzag noise and outputs zigzag noise periodicity for each group of traces. Once it has been identified, the zigzag noise can be removed from the VSP data and improve formation evaluation.Type: GrantFiled: May 12, 2020Date of Patent: May 24, 2022Assignee: Halliburton Energy Services, Inc.Inventors: Mark Elliott Willis, Pedro William Palacios, Andreas Ellmauthaler, Xiaomin Zhao
