“…Hydraulic debris removal drilling utilizes water as the drilling and flushing medium. 44 Water penetrates the coal mass in soft coal seams with well-developed fractures, disrupting the cohesion between coal particles, the effective structural force, and the original stress state. 45 This can lead to phenomena like borehole wall spalling, collapse, and instability, even resulting in incidents like buried drilling and stuck drilling.…”

During the gas extraction drilling process, especially the soft coal seam drilling process, due to the constraints of geological conditions, technical conditions, and other factors, it is easy to encounter stuck holes, blowout, lost circulation, and hole collapse, which affect the realization of efficient gas management. In the petroleum industry, microfoam drilling fluid has unique advantages as a drilling and flushing medium. Through the response surface method, this study conducts a preliminary experimental study on the types of foaming agents, foam stabilizers, modified bentonite materials, and filtrate reducers and determines the optimal formula as 3.98% modified bentonite + 0.586% compound foaming agent + 0.776% foam stabilizer + 1% sulfonated phenolic resin + 2% carboxymethyl starch sodium. The performance of the microfoam drilling fluid system is tested. Subsequently, a simulated soft coal seam drilling test is carried out to verify the effectiveness of the developed directional microfoam drilling fluid for protecting coal rock holes. This microfoam drilling fluid system technology can improve the drilling quality of the sealing section of coal seam gas extraction drilling and effectively improve the gas extraction rate of coal mines.

“…Particularly, numerous studies that apply Computational Fluid Dynamics (CFD) for the description of annular multiphase (fluidsolid) transport of dense and dilute particulate mixtures have emerged over the past decade (Han et al, 2010;Duan et al, 2010;Zaisha et al, 2012;Demiralp, 2014;Akhshik et al, 2015;Rooki et al, 2015;Heydari et al, 2017;Epelle and Gerogiorgis, 2018a;2018b;Huque et al, 2020;Yan et al, 2020). Recently, important new perspectives such as the application of ionic liquid-based muds (Rasool et al, 2021), modelling the settling behaviour of non-spherical particles using neural networks (Zhu et al, 2021), hydraulic pulsed jet technology (Wang et al, 2021), modelling cuttings lag distribution in directional wells (Naganawa, et al, 2021), the use of a grooved drill pipe for enhanced mud circulation and cuttings transport (Jiang et al, 2021) and the flow of fine solid particles (Movahedi and Jamshidi, 2021), have been considered in the field of cuttings transport.…”

“…Muds and cuttings transport phenomena occur through their respective drilling [10] and the annular column of the drilling system, factoring in the position of the drilling pipe at the time of rotation. However, previous studies over the years dived into the concentric and eccentric [11][12][13] effects of drilling pipes and their capacity to lift cuttings to the surface; while other research experimented [14][15][16][17][18], a few considered optimizing these effects with computational analysis [19][20][21][22][23][24][25][26][27][28][29][30].

A CFD Validation Effect of YP/PV from Laboratory-Formulated SBMDIF for Productive Transport Load to the Surface

et al. 2022

Several technical factors contribute to the flow of cuttings from the wellbore to the surface of the well, some of which are fundamentally due to the speed and inclination of the drill pipe at different positions (concentric and eccentric), the efficacy of the drilling mud considers plastic viscosity (PV) and yield point (YP), the weight of the cuttings, and the deviation of the well. Moreover, these overlaying cutting beds breed destruction in the drilling operation, some of which cause stuck pipes, reducing the rate of rotation and penetration. This current study, while it addresses the apropos of artificial intelligence (AI) with symmetry, employs a three-dimensional computational fluid dynamic (CFD) simulation model to validate an effective synthetic-based mud-drilling and to investigate the potency of the muds’ flow behaviours for transporting cuttings. Furthermore, the study examines the ratio effects of YP/PV to attain the safe transport of cuttings based on the turbulence of solid-particle suspension from the drilling fluid and the cuttings, and its velocity–pressure influence in a vertical well under a concentric and eccentric position of the drilling pipe. The resulting CFD analysis explains that the YP/PV of SBM and OBM, which generated the required capacity to suspend the cuttings to the surface, are symmetric to the experimental results and hence, the position of the drill pipe at the concentric position in vertical wells required a lower rotational speed. A computational study of the synthetic-based mud and its potency of not damaging the wellbore under an eccentric drill pipe position can be further examined.
