Definitions
- the invention is not suitable for industrial purposes and may be used to intensify wells by increasing the pressure.
- the inactive form of sulfuric acid provides a gel-like mixture of acid and aerosol (SOUTH).

- a cheap and well-known method is the low effective working area of a commercial area.
- inactive acid supply to inactive form it is agreed to by the well-known method that the interaction of nitric acid with the compound takes place.
- nitric acid carbamide is available for purchase only with the formation of the original components - nitric acid and carbamide.
- Part of the resulting nitric acid is involved in the oxidatively-reactive processes of the interaction of gas and oil oxidizing gases. Processes in the borehole come with the release of heat, which is sufficient to remove the asphalting-pleasures from the free zone of the area.
- the remaining part of the developed nitric acid is reactive with a mineral component of the industrial zone of the industrial zone.
- nitric acid The quick release of nitric acid restricts the radius of its penetration into the area, which worsens the absorption of minerals in the region. Residual acid easily opens up the aluminous component of the surface, as a result of which there is a slight loss of channels, which worsens the pressure. This It determines the low efficiency of the working area of a comfortable area.

- samples of the mixture of hydrates of four were prepared with a different composition of the Water Cup for 1 month of non-food;
- the following groups of hydrants were used: four titanium hydrides:
- the content of the active and healthy water is equal to, wt. %: 60.8; 60.1; 58.9; 56.4; 54.6, respectively.
- the indicators of the chemical inactivity of the hydraulics are the stability of the viscosity and the ⁇ values of the test mixture. The data obtained are presented in table 1. Table 1.
