Structural Design Improvement And Simulation Research Of Hydraulic IMPactor Drilling Tools In Deep And Ultra-Deep Wells

As my country's oil and gas resource exploitation continues to move westward,the number of deep and ultra-deep wells is constantly increasing,leading to long drilling cycles and greatly increasing drilling costs.The jet suction hydraulic iMPactor converts the pressure energy of the drilling fluid into mechanical energy,combines the advantages of conventional rotary drilling and percussion drilling,and effectively improves the efficiency of deep and ultra-deep well drilling.In this design,the development status of deep and ultra-deep well drilling and hydraulic iMPactors at home and abroad was first understood and analyzed,and the design and research direction of this article was established.Then,the structural design of the deep well and ultra-deep well hydraulic iMPactor was carried out,based on fluid mechanics and dynamics,a dynamic model was established to understand the factors that affect its working state.Through the use of Workbench Fluent and ICEM CFD software to simulate the jet-suction hydraulic iMPactor,the results are analyzed,and the feasibility of the deep and ultra-deep well hydraulic iMPactor is verified.Finally,by adjusting the nozzle size and choke ring size in key parts,the flow channel simulation was performed again.By coMParing the simulation results,plus the verification of subsequent tests,the optimal configuration size of the key parts of the deep well ultra-deep well hydraulic iMPactor was obtained.
