TOMSK, Aug 6 – RIA Tomsk. Scientists of Tomsk Polytechnic University (TPU) developed technology of the energy efficient hammerless hydraulic impulse machine which will help to make drilling mechanisms cheaper and "hardy", is reported on the website of the university on Tuesday.

It is added that drilling and rock destructive operations are conducted in various industries (mining, laying of underground services, construction, space programs). Nevertheless, there are often problems connected with need of overcoming inclusions or rocks of high hardness in the course of the horizontally directed well-drilling. It demands use of a rational way of their destruction.

"Shock mechanisms of drilling rigs form power impulses of the irrational form which is not considering property of rock to resistance for its destruction. Such form of impulses and short duration of their impact on rock reduces depth of introduction of a crown in it and forms the stretching wave destroying the boring tool", – the press service reports.

As professor of Division for Oil and Gas Engineering of TPU Lev Saruyev whose words are cited in the message explains, there was a need for development of essentially new shaper of the power impulses corresponding to process of resistance of rock: "The offered development has indisputable advantages: mass-dimensional characteristics, energy efficiency, explosion safety".

New drilling rig is based on formation and transfer of a power impulse (based on the wave theory of impact) and application of the special threaded connection of the drilling pipes providing effective transmission of energy of impact in a rock destruction zone.

As the authors of the development consider, the technology will allow to reduce the cost of drilling operations and to increase the require repairs periods (due to lack of the colliding parts in the mechanism drive). The mobility of the installation is provided due to lack of the compressor or the oil-pumping station. The scientists plan to be focused on a series of practical experiments directed to creation of an industrial sample of essentially new class of rock cutting machines.

Tomsk Polytechnic University is the leading technical university of the country. It is founded in 1896 as the Tomsk Technological Institute of Emperor Nicholas II. Became the first engineering university in the Asian part of the country. Today TPU enters top-10 the universities of Russia and top-400 the universities of the world.

In June, 2019 TPU entered top-10 the rating of the universities made by the Russian editorial office of the Forbes magazine, having taken the ninth place; it is the best result among not capital universities of the country.
