A Low-Cost Calibration Strategy for Measurement-While-Drilling System

IEEE Transactions on Industrial Electronics, 2018
The measurement-while-drilling (MWD) system is mainly used to draw borehole trajectory in a coal mine. However, its measurement error directly demonstrates a deviation between the drawing locus and the actual path. Thus, it is imperative to effectively compensate the error in advance. In this study, the traditional-integrated error model is adopted and

Measure While Drilling Pulse Signal Transmission Speed Theory

2020 IEEE 20th International Conference on Communication Technology (ICCT), 2020
This paper combines the actual working conditions of MWD or LWD system, draws on non-Newtonian fluid transmission pipeline dynamics principle, and establishes a power-law fluid average friction pipeline model. On this basis, we established drilling fluid pulse signal transmission speed equation related to frequency by using liquid-electric simulation ...

Measuring-While-Drilling: Transforming Geotechnical Site Characterization Drilling

International Conference on Measurement While Drilling Proceedings
"Interest in Measuring-While-Drilling (MWD) within the U.S. geotechnical industry has been growing significantly over the last several years. This largely began after the Federal Highway Administration (FHWA) promoted the use of MWD as part of an effort known as Advanced Geotechnical Methods of Exploration (A-GaME) starting in 2019, which significantly

Measurement While Drilling in the Illinois Subsurface: Drilling Versus Compound Parameters

Transportation Research Record: Journal of the Transportation Research Board
This study focuses on the investigation of detecting soil profiles encountered during exploratory drilling using continuous drilling parameters recorded in real-time, known as measurement while drilling (MWD). MWD is an instrumented drilling technique where drilling parameters, such as drilling rate, rotational speed, thrust, and torque, are recorded ...

Keynote Lecture: The Role of Drilling Efficiency in Geotechnical Measuring While Drilling

International Conference on Measurement While Drilling Proceedings
The emergence of measuring while drilling (MWD) as a quantitative tool for geotechnical site characterization highlights the need to understand and optimize drilling efficiency. This paper presents a comprehensive framework that classifies drilling parameters by origin and influence, identifies mechanical inefficiencies across distinct drilling phases,
