“…At 200 rpm, the expected effective distance of the blade with helical angle α = 0° can exceed 0.95 m, while an additional serious deposition phenomenon is found where the swirling effect is about to disappear, and the deposition phenomenon is slightly alleviated and stabilized after a brief existence. This is the local dune flow phenomenon of the moving bed region caused by the weakening of the swirling effect …”

“…This is the local dune flow phenomenon of the moving bed region caused by the weakening of the swirling effect. 38 Figure 8 shows the profiles of cuttings volume fraction at z = 1.0 m with four rotational speeds. The swirl intensity decreases gradually along the flow direction, and the tangential kinetic energy transferred to the particles decreases at a certain rotational speed.…”

The application of the hole cleaning device in downhole is a new technology for removing cuttings bed, and it can increase the efficiency of cuttings transport. This paper mainly studies the effects of the helical angle and the rotational speed of the blade of the hole cleaning device on the swirl strength of decaying swirl flow and drilled cuttings deposition behavior. A three‐dimensional computational fluid dynamics (CFD) model is established using the Eulerian‐Eulerian two‐fluid model, Realizable k‐ε turbulence model, and Sliding Mesh technique for simulating the two‐phase fluid flow. The results have been compared with available data in the literature, and a good agreement is found. In order to understand the decay behavior of the swirl flow along the flow direction, the initial swirl strength, the swirl number, and the decay rate of swirl are analyzed in detail in single phase. The effects of the swirl flow induced by the blade on the deposition behavior of drilled cuttings under different rotational speed and helical angle are studied. A new deposition index is used to evaluate the effective distance and hole cleaning efficiency of the swirl flow under various parameters. It has been observed that using the hole cleaning device can improve the hole cleaning performance. The research results of this paper is instructive to the design of the hole cleaning device using in the drilling engineering.

Sand production in the life of oil and gas reservoirs is inevitable, as it is co-produced with oil and gas from the reservoirs. Its deposition in petroleum pipelines poses considerable risk to production and can lead to pipe corrosion and flow assurance challenges. Therefore, it is important that pipe flow conditions are maintained to ensure sand particles are not deposited but in continuous motion with the flow. The combination of minimum gas and liquid velocities that ensure continuous sand motion is known as the minimum transport condition (MTC). This study investigates the effect both of sand particle diameter and concentration on MTC in gas/liquid stratified flow in a horizontal pipeline. We used non-intrusive conductivity sensors for sand detection. These sensors, used for film thickness measurement in gas/liquid flows, was used here for sand detection. We found that MTC increases with increase in particle diameter for the same concentration and also increases as the concentration increases for the same particle diameter. A correlation is proposed for the prediction of sand transport at MTC in air-water flows in horizontal pipes, by including the effect of sand concentration in Thomas's lower model. The correlation accounts for low sand concentrations and gave excellent predictions when compared with the experimental results at MTC.

“…The concept of transportation is simple; nevertheless, the proper design of the pipeline requires complex models. According to Leporini et al (2018), several researchers tried and failed to develop a model to characterize slug transportation in pipelines accurately. Turian et al (1987) performed a detailed examination of the critical velocity in pipeline flow on non-colloidal slurries.…”

The hydraulic transport of solids has been adopted for many years. However, deposition of the solid particles in the pipe can cause equipment failure, pipeline erosion, and excessive pressure drop, resulting in financial and environmental problems. The critical velocity, also known as critical deposition velocity, is the limit of particle deposition when a moving bed of particles starts to form on the bottom of the pipe. The determination of the critical deposition velocity is an essential step in slurry pipeline`s design and operation. This paper assesses the influence of the velocity in the particle deposition of slurries containing coarse particles of apatite and hematite industrial concentrates and quartz. We used CFD to solve Navier-Stokes for the fluid phase and DEM to solve Newton`s equations governing the granular particles. CFD and the DEM modules adopted OpenFOAM and LIGGGHTS. Numerical results were compared with experimental data from the literature.
