Pulse Seismic Yenisei to a new level

8-9 December 2011 in the city of Krasnoyarsk Krai Minusinsk took the test working models of the two types of electromagnetic pulse sources of seismic shear waves, designed for multi-wave seismic data.

In 2010, the company of "Yeniseygeofizika" participated in the federal competition (Ministry of Education and Science, U-218), a victory which allowed to obtain a grant for the implementation of an integrated project "Development and implementation of an effective impulse non-explosive seismic technology in Eastern Siberia, the deployment of scientific research and training in the Siberian Federal University. " The government has allocated 250 million rubles of subsidies, as many put "Geotech Holding" owner "Yeniseygeofizika" — and the project went …

Pulsed electromagnetic sources of seismic waves "Yenisei" — a unique technology exploration, created and implemented in the 80s in the Krasnoyarsk Territory. It’s kind of a fantastic electromagnetic gun, but it does not disperse projectiles and sends an elastic wave into the ground — then catch the reflected echo sensitive geophones, so the mother-planet ultrasound done, and geologists know where to look for oil and gas.

The invention is protected by patents and plant Minusinsky "Geotehnotsentr" branch "Yeniseygeofizika" annually produces dozens impulsnik in different versions — the sleigh, wheel and floating (like a catamaran).

These are our sources of "Yenisei" — sleigh and wheel on the Taimyr Peninsula, near the plateau tableland, as well as water — "Yenisei-HEM-100" — on the Angara River.

Environmentally friendly non-explosive Seismic demand not only in Russia, the sources of "Yenisei" purchased by foreign geophysical enterprises — Iranian, American and European. The Americans even managed our technology "prihvatizirovat" — put on your crawler chassis and sold as its latest development. That is why what we want as soon as possible to win the international market — the benefit to our "Yenisei" no competitors in this specific area, like shallow water, and it is precisely along the rivers, and can only lead seismic surveys in many places.

This Iranian Geophysics at p. Biryusa oversee the work of our sources "Yenisei-VEM-50" and the second photo — source modules "Yenisei" in the United States on American tracks (emitter of seismic waves can be seen at bottom right).

Now, thanks to government support, the technology of "Yenisei" to a new level: upgraded chargers, a system of adaptive management — will learn to have more control over the sources of the seismic action, depending on the operating conditions. Already there was an advanced satellite positioning technology that allows for topographic location in the mountain and taiga area.

Research and development activities are carried out in the mentioned areas of the Siberian Federal University specialists and designers Novosibirsk organizations — co-project. A SFU students will soon be able to train on a specially designed seismic geophysical test site.

Sources of seismic shear waves — as part of the project. Creating such — not a trivial problem. For all the theoretical calculations using seismic shear waves (sometimes called S-waves) should significantly improve the seismic capability, but in practice, this problem is still not solved. Sources of transverse waves constructed in the early 50’s in various countries, including the Soviet Union, but the existing models, suitable for methodical work in the field, and did not appear. One reason for the failure was that the vibrations were used to generate the mechanics and pneumatics, while the electromagnetic pulse principle remained unclaimed.

And so, as a result of work on complex project created, as they say "the iron", two versions of the source of transverse waves. For their comparative test of the eighth December in Minusinsk the factory "Geotehnotsentr" to participate in the Scientific and Technical Council, brought together scientists and engineers from Moscow, Novosibirsk, Irkutsk, Yekaterinburg. Specialists from different sciences, both technical and geological, and even physics and mathematics, as the seismic problem is known to be one of the most high-tech.

Comparing the work of two machines. One is built upon the basis of the tractor and the other — it’s a massive sleds that are running pulsed electromagnets. As shown by measurements on three axes (Z-axis served specially drilled well with the receivers of the type with vertical seismic profiling) — both sources successfully create a transverse seismic wave. It was established by experts from the full-wave seismic laboratory of the Institute of Petroleum Geology and Geophysics SB RAS, specially invited to the test.

At the final meeting of the NTS its chairman — the first vice-president of "Geotech Holding" Hillary — invited the Forum to join the Science and Technology Council, which will appear in the structure of Geotech in the near future. And the head of a complex project from SFU professor George Shaidurov said that the result of the work will not only be a new high-tech production of "Ensieygeofizika" but will a special science school — Krasnoyarsk Scientific Center of non-explosive seismic.
