Mar 1, 2023 · By the means of AI, the bit wear condition is determined based on drilling vibration and bit catastrophic failure is predicted. Feedforward neural network (FNN) models are designed and examined to classify the drill bit wear state as a supervised learning approach.

Mar 1, 2025 · This paper proposes a drill bit wear monitoring method based on CNN, BiLSTM, and MHA. By correlating drill bit wear with footage drilled and drilling time, it assigns wear labels to each depth segment, addressing the issue of limited training data.

Mar 1, 2021 · The bit wear is defined as the bit wear index evaluated based on the abrasion value and drilling rate index. 6, 8, 9 Ren et al. 10 showed that effect of the size of the graphite powder is an important parameter on the wear properties.

Jan 10, 2022 · Doing so can effectively reduce the wear of the bit and prolong its service life. This study provides guidance for predicting the wear of a PDC bit when drilling in conglomerate, adjusting drilling parameters reasonably, and prolonging the service life of the bit.

Sep 8, 2021 · The main objective of this investigation is to develop a new approach to predict bit wear during drilling. The continuum modeling approach was used to simulate drill bit–workpiece interactions and wear mechanisms and evaluate the effects of key operating parameters.

properties and bit wear mechanism, and argues the options to determine the bit wear rate. The test models indicate that the rock properties can give an idea of bit wear.

Bit sharpening techniques should only be used when absolutely necessary as they can have an adverse effect on overall bit life if they have been improperly performed. Method 1: Bit Face Dressing (Preferred Method) Remove the bit from the drill hole and grit blast the bit face with an abrasive media such as aluminum-oxide or silicon-carbide powder.

Mar 6, 2018 · This paper presents a new workflow for monitoring drilling efficiency in real time during drilling operations. Based on a bit-rock interaction model, the new workflow provides parameter estimations, such as bit wear and in-situ rock strength, obtained from typical real-time drilling measurements.

Oct 20, 2020 · The bit wear is an important parameter used to calculate the bit consumption and wear costs [2, 3]. The bit wear in rock drilling is a major factor involved in determining the drilling cost, and may determine the drilling method for a given rock [4].

Consequently, there is a need to establish a model for the purpose of assessing the level of bit wear. This paper introduces a novel approach for examining the correlation between drilling...
