Lifting capacity efficiency using polyethylene beads: A numerical investigation

Global demand growth has driven the development of more inventive methods for enhancing oil well drilling at lower prices and avoiding operational issues that slow down drilling. The present research is significant because lifting capacity may be increased by inserting polymer beads into mud instead high-cost additives. numerical cuttings trajectory simulation was performed using commercial ANSYS FLUENT 2019 R3 software to account influence collisions. To test cuts transport behavior owing presence liquid solid phases, (Eulerian-Eulerian) model utilized. mind transfer rate determined in this varying operating parameters (drilling flow temperature, size inclination, drill pipe rotation eccentricity) with without polyethylene (PE) beads. result show average error ratio between results 5 % experimental researcher Ismail. higher percentage PE entering fluid, concentration within annular space model. reaches 28 when fluid flows a speed 1.2 m/s adding While it decreases (17, 21, 24) (6, 4, 2) %, respectively, same velocity fluid. decrease 14 are 6 0 rpm, increases 65 120 rpm reduction 30 entered temperature 20 ℃, while reduced 50 ℃ inserting. ability move cuttings, but affected amount angle, as we found effect effective clear angle 0˚ (vertical). its becomes less directional wells very weak 90˚ (horizontal).The good positive large-sized compared impact smaller-sized cuttings.
