Special Issue Information
Dear Colleagues,
The drilling wellbore is a complex multiphase flow system where liquid, solid, and gaseous materials coexist and flow simultaneously. The drill string rotates and moves up and down within the wellbore filled with multiphase fluids, and the interactions between them are crucial. The interactions between the multiphase flow and the cuttings are the core aspect that determines the drilling’s efficiency and safety, with the core issue being “cuttings migration.” The multiphase flow during the drilling process and its interactions with the drill string and cuttings constitute a dynamic and coupled system engineering problem. The core challenges lie in the following: (1) flow assurance: ensuring the effective circulation of drilling fluid and safely controlling the wellbore pressure; (2) wellbore cleaning: efficiently transporting cuttings out of the well and preventing the formation of a cuttings bed; and (3) equipment integrity and drilling efficiency: reducing the damage to the drill string caused by vibrations and optimizing parameters to achieve safe and rapid drilling. Modern drilling operations rely heavily on dynamic and static mechanical fluid dynamics and impact dynamics simulation software to model these complex interactions. These models combine formation pressure prediction, drilling fluid performance, drill string combinations, and drilling parameters to assist engineers in optimizing designs before operations, conducting real-time monitoring and decision-making during operations, and addressing the above-mentioned challenges to ensure the safety, efficiency, and economy of drilling operations.
This Special Issue on ‘Multiphase Flow-Material Interaction in Drilling Processes’ seeks high-quality papers on multiphase flow and its interactions with various materials during the drilling process. Topics may include, but need not be limited to, the following:
- Rock mechanics testing, multi-field coupling, and numerical simulation.
- Drilling, hydraulic fracturing, and mining engineering.
- Advances in safe drilling theory and field practices.
- Research progress and case studies on drilling speed enhancement.
- Artificial intelligence and data science in imaging techniques and non-destructive testing.
- Multi-scale modeling of multiphase flow systems.
- High-pressure water jet applications in petroleum and other engineering industries.
- Multiphase flow during drilling process and multiphase flow–material interaction.
