Research on Erosion Wear of Slotted Screen Based on High Production Gas Field

Erosion wear is a common failure form of slotted screen in service. In this paper, based on CFD software and sand production data gas field the Tarim Basin, particle velocity shear force at slot flow sieve tube were studied to determine maximum area erosion; same time, velocity, viscosity, size concentration sand-carrying fluid analyzed by orthogonal test, regression model multi-factor erosion rate was established. ? Through analysis four factors degree dependent variables, order primary secondary are: liquid rate, concentration, diameter, effect viscosity diameter relatively small; ? According variance range, combination scheme minimum generation obtained, calculation reduce abrasion actual oil process, reasonable control precise method design precision selection can be adopted; it provides basis for long-term effects high-yield field.
