Abstract Hydraulic sandblasting perforation plays a crucial role in the fracturing and reconstruction of unconventional oil and gas reservoirs. The jet nozzle is an essential part of the hydraulic perforation tool. Insufficient penetration depth, caused by excessive jet distances, presents challenges during the perforation process. To overcome this, an optimization design of the nozzle structure is required to enhance the perforation efficiency. In this paper, a computational fluid-dynamic model for conical-cylindrical nozzles has been elaborated. To further improve the rock-breaking efficiency of the jet nozzle, a fillet design is introduced at the nozzle inlet section. The… More >
