Study the possibilities of application impact pulses in construction of wells

Purpose. Analysis of the theoretical foundations, design schemes and methods for calculating technical technological support drilling cycle operations using dynamic shock impulses in order to intensify destructive processes at bottom a well under construction. Research methodology. Laboratory studies features functioning devices generating pulses were carried out modern experimental research, processing research results EXCEL, MATHCAD environment, instrumentation (pressure gauges, flow meters) materials. The circulation actions was modeled on pilot wells training site Dnipro University Technology ZIF-650M rig UKB-4P rig, also corresponding main tool. results. Theoretical practical foundations process operation pulse generators - hydraulic hammers are formulated. A detailed analysis specific works shows prospects development hydropercussion that effective both from standpoint fracture mechanics energy intensity this process. This, turn, will make it possible determine most rational parameters destruction rock well, is, maximum productivity with minimal consumption. basic principles mechanism impact studied derivation important analytical dependencies characterizing their workflow. Originality. high efficiency percussion-rotary method lies significant value rate application breaking load, which, when percussion machines, is subject wide variation. Practical implications. considered radically new implementation (hydraulic hammers) created, use which ensure constancy deepening hole degree efficiency, addition, organically these eliminating complications.
