Numerical Simulation Optimization and Experimental Study on Erosion of Full Bore Sliding Sleeve Soluble Ball Seat
In response to the problems of limited fracturing stages,difficulty in drilling ball sock-ets,and inability to achieve full wellbore diameter in conventional ball throwing sliding sleeves,a study was conducted on the full diameter soluble ball socket type sliding sleeve.Erosion simula-tion was conducted using fluent software on the fracturing ball socket used for full-bore sliding sleeves.The space-filling design method was used to conduct parameter tests on the"concave"structure of the ball socket,and the response surface prediction was performed to seek the opti-mal parameter value through the screening method.Graphene and cemented carbide were pre-ferred to be erosion-resistant coatings,and the erosion resistance effects of the two materials were compared through erosion field tests.The results show that the average loss of the concave structure ball seat after optimization of response surface parameters is significantly lower than that of the original model,and the erosion test shows that the erosion resistance of the surface carbide ball seat is better than that of the graphene ball seat.The research results have a guiding significance for optimizing and improving the erosion and wear resistance of ball seats.
