Core Business: Intensive researches on the main problems of source of
raw material base development, rational usage of mineral resources, elaboration
of progressive power – saving technologies of mineral resources extraction and
processing.
Overview: New technology of drilling and timbering of the
boreholes using the flash effect.
A
borehole tool for boring rocks by fusing is intended for drilling boreholes in
loose rocks with simultaneous ecologically appropriate timbering without pipes
at the expense of seal and thermal conversion. Diameter of a penetrator – 60
mm, watt consumption – 6 – 7,5 kWt; penetrator body temperature – 1500-1600 °C.
The
oil and gas well construction cardinally simplifies a refusal from multistring
constructions and passage to unistring construction is supposed. A reduction of
standard sizes of a whole drilling tool complex is supported, so long as using
of unistring construction completely excludes drilling of bores for strings of
a big diameter. Then a sharp reduction of requirements for rated load capacity
of drilling rigs will lead to evident economic consequences in the field of
energy and resources saving and to natural reduction of types of digging rigs
on the whole. Such method provides possibility in the overwhelming majority of
the geologo-technical conditions to abandon use of clay fluids as flushing
fluid and irrigate drill holes by water. The ecological problems of the Earth
interiors are cardinally solved because there is no need in cross-flow
transfers and to pump reactive solutions down seams both drilling fluids and
grouting mortars. Social and ecological effect from the realization of
suggested technology also can be valued considering that the majority of the
advantages of this mean simplify the team work and make it more comfortable.
