Tooling materials science| Zusammenfassung: | Purpose. Detailed analytical and laboratory study and analysis of the
conditions for stable operation of hydraulic percussion drilling machines, as well as consideration of prerequisites, factors, features, etc. modernization and technical and
technological transformation of individual units and instrumental support for
hydraulic hammers and the corresponding method of well construction.
Methods. The main factors of technical and technological support of the
processes of hydraulic percussion construction of wells for various purposes,
corresponding to the circumstances characteristic of rocks of medium hardness and
hard ones, have been studied by consistently holistic and complex laboratory, as well
as analytical methods. The influence of the parameters of the completed cycle of
operation of existing and proposed innovative percussion drilling machines on the
course and results of the formation of bottomhole conditions for the destruction of the
rock mass is considered and evaluated.
Findings. The main stages of the technological process of hydraulic
percussion drilling of wells and its advantages over other methods of destruction of
the rock mass are characterized. The existence of significant shortcomings in a large
number of proposed and used designs of hydraulic percussion machines is shown,
which do not allow to fully ensure the manifestation of the potential capabilities of
the percussive-rotary method of drilling wells. The design features of innovative
hydraulic percussion machines for well construction in their working cycle of
generating dynamic impulses are considered. A consistent method for determining
the energy parameters of percussion drilling machines and the influence of these
factors on the technical and economic indicators of the bottom hole of wells under
construction in various mining and geological conditions is proposed and analyzed.
Originality. The conditions for the rational conduct and operational efficiency
of wellbore casing operations, during its construction in the thickness of chemogenic
deposits, correspond to certain parameters of the used grouting systems and
measures aimed at eliminating the influence of technological shortcomings of the
wellbore.
Practical implications. The presented results of detailed laboratory and
analytical-constructive studies, as well as some generalizations of industrial bench
data are basic for the design of technical support and regime parameters of the
process of hydraulic percussion construction of wells with guaranteed provision of high technical and economic indicators. Data on the study of internal circulation
processes in hydraulic percussion machines are the initial factors for substantiating
the design and technological parameters of innovative devices for creating dynamic
impulses in order to intensify the processes of deepening the well bottom. |
