Abstract of thesis
Theme and name substantiation, work urgency.
Hydroshock mechanisms are widely applied at drilling of wellbores in sediments on a sea shelf. Thus as the pipeline to fluid supply in a wellbore are applied both drilling pipes, and high pressure hoses. Thus known dependences of parametres of a working cycle of the hydraulic hammer on the area of section of the channel of the pipeline, but influence of properties of a material and a thickness of its walls on working cycle was not considered. Though these parametres define speed of distribution of a hydroshock wave in the channel of the pipeline which, in turn, influences hydroshock pressure in the mechanism cylinder, and accordingly and on working cycle.
Thus, for practice of percussive drilling of wellbores on a shelf rather actual problem is definition of influence of parametres of the pipeline on performance of the hydraulic hammer tool. It will allow to define more precisely frequency-power characteristics of the hydraulic hammer depending on application with various pipelines. In this connection the work theme is topical.
Communication of work with scientific programs, plans, work performance under the demand of scientific institution or the industrial organisation.
Work is executed under Joint-Stock Company "Company" Jugovostokgaz" demand and connected with realisation of the Nation-wide program of development of a mineralno-raw-material base of Ukraine (the Law of Ukraine from 2/22/2006 № 3458-IV)
The work purpose - an establishment of influence of parametres of the pipeline on the characteristic of a working cycle of the hydraulic hammer for drilling of wellbores on a shelf and adjustment of its power characteristics at work with various pipelines.
Research problems.
1. Working out of the stand for definition of elastic parametres of the pipeline and speed of distribution of a hydroshock wave.
2. The analysis of influence of parametres of the pipeline and speed hydroshock waves on the characteristic of a working cycle of the hydraulic hammer for drilling of wellbores on a shelf.
3. Improvement of recommendations about technology of application of the hydraulic hammer at operation with various pipelines.
Idea of work - definition of laws of work of the hydraulic hammer at work with pipelines with different speeds of distribution of a hydroshock wave.
Object and subject of research.
Object of researches – hydraulic hammer mechanisms for drilling of wellbores on a shelf.
Subject of researches - working processes in hydraulic hammer mechanisms for drilling of wellbores on a shelf.
Expected results, their novelty and importance.
New results:
- Dependences of performance data of the hydraulic hammer on parametres of various pipelines.
- Recommendations about design of the hydraulic hammer at its application with various pipelines.
Importance of work is definition of influence of elastic parametres of the pipeline for work of the hydraulic hammer mechanism and a substantiation of its design for various conditions of application.
