Electric drill for drilling wells, working on the Yutkin effect (electrohydraulic effect)

In the 30s of the 20th century. Soviet scientist and inventor Lev Yutkin, discovered a method for converting the energy of an electrical discharge into mechanical energy. To do this, he produced a discharge between electrodes in water. In this case, local expansion in the aquatic environment occurred. And since Since water practically does not compress, then the water transferred all the energy of local expansion from the discharge to the walls of the container or to the destruction of those substances that were in the water. Moreover, even at the molecular level.

In the postwar years, he continued his experiments. And there are many prospects for using this effect. The main ones are:

• obtaining crushed stone and crumbs from rocks;
• obtaining nitrogenous fertilizers from chernozem and peat;
• splitting stones in quarries;
• embossing and pressing of parts;
• production of diamond powder from graphite.

Installation diagram for crushing stone into powder. To obtain a discharge in water, it is necessary to obtain a voltage of tens of kilovolts. In this case, a water hammer is formed with a pressure of hundreds of thousands of atmospheres. The water hammer destroys even granites.

You can watch the old Lennauchfilm documentary about the invention of Lev Yutkin:

It lists some areas where the author wanted to apply the technology and where experimental tests were carried out. We will talk about some of them in a separate article. one theme exactly intersects with the theme of the owners of suburban areas. Namely, it will be interesting for those who grow something there.

And in this article I will show one interesting direction where the Yutkin effect can help in laying communications, in drilling for water supply and in drilling for pouring piles.

The drilling method is as follows. An initial depression is dug out, filled with water, and a pipe with electrodes placed inside the lower part of this pipe is lowered there. A series of discharges occurs in the water. The water hammer crushes loose rocks, allowing the electric drill to go lower:

The method is similar to core drilling with the only difference that you do not need to regularly pull out, remove and clean the tool from soil. Even if the drill encounters hard rocks like sandstone or granite, the water hammer will pass them too, but at a lower rate. According to calculations, this method allows you to pass up to 1 m / min in clay layers, going deep into the ground to the required depth.

Moreover, this drill, upon reaching the aquifers, is capable of destroying them and increasing the flow rate of water. Hydraulic fracturing - this principle is applied in shale oil production technology. It remains only to lower the casing and pump the well from the remains of clay and sand.

Similarly, you can create holes for pouring piles. You can use the electro-hydraulic effect during pouring. In this case, a thickening is formed inside the body of the pile, the bearing capacity of the pile increases. The technology can also be used for laying communications, for directional drilling.

Demonstration of an experimental setup of such a drill:

Short description:

Found a patent on this topic (RF Patent No. 144631):

But I could not find photographs of experimental developments in the form of an electric drill and power supplies. Probably, everything remained at the level of ideas and experiments.

In my opinion, the topic is quite interesting and promising. If the cost of drilling is lower, and the rate of passage of the rocks is higher than modern technologies for drilling water wells, then the method of drilling with electrohydraulic effect is doomed to success. What do you think?
