Description

technical field

[0001] The invention relates to the field of hydraulic sandblasting fixed-point perforation, in particular to a mechanical parameter calculation model and method of hydraulic sandblasting fixed-point perforation. Background technique

[0002] The hydraulic sandblasting fixed-point perforating process is to convert the pressure energy into kinetic energy with the help of jet tools under the condition of high-pressure and high-speed sand-carrying liquid injection, and use high-speed fluid impact to form a perforation channel, which is shot through the casing, cement sheath and formation in sequence, thereby completing the process. Hydraulic perforation forms a clean fluid channel in the formation, reduces the skin factor of oil and gas wells, and improves the perfection of oil and gas wells and formation permeability. According to investigations, for the hydraulic sandblasting fixed-point perforation technology, predecessors have carried out some mechanism expe...
