The invention relates to the field of purification of the earth's surface and interior from spills of petroleum products and can be used in various industries of petroleum products by consumers.

A known method of cleaning soil from petroleum products by the use of an aqueous solution of the bacterial preparation “Poutical by transfer of petroleum products in an environmentally neutral connection (see “Poutical” for the purification of water and soil from oil pollution. Instruction. Berd plant biological products. 1992). The method involves the preparation of nitrogen-phosphorus fertilization, ptkogo method is the ability to use the drug only when average daily temperature is above +10With the duration of the cleaning process of the treated area (10-14 days), low power cleaned layer (up to 25 cm), high specific consumption of the drug and the loss of petroleum products for their consumer qualities.

The closest technical solution is the way extraction of metals by the method of underground leaching (see uranium Mining by underground leaching. Ed. by C. A. Shalimov. M: Atomizdat, 1980). The method involves the construction of a network odajnyk and injection wells, the equipment in the interval permeable ore-bearing horizon filters, flow in injection wells leach solution and extraction through these pumping wells solution useful component to the surface for further processing.

The disadvantage of this method lies in the need for construction of a network of injection wells, the possibility of testing the limited capacity of the horizon.

The aim of the invention is to increase the efficiency of cleaning the surface and underlying rocks from spilled oil.

This goal is achieved by the fact that in the method of cleaning the surface and underlying rocks from petroleum products, including construction odajnyk wells, according invented apolnet water, and through coarse filters installed in the well above the lower limit of the distribution of petroleum products, pumps pumped to the surface of the oil-water mixture, where you divide by the oil removed in the tank, and the water, which serves to fill a limited bulk space.

In a preferred variant of the method the network odajnyk wells perform from zakonchennih and contour wells located within the embankment of waterproof material and abroad.

The use of the proposed solutions will allow you to complete the task: to increase the efficiency of cleaning of the surface and underlying rocks from spilled oil.

The inventive method of cleaning the surface and underlying rocks from petroleum products, including construction network odajnyk wells, differs from the known, taken as a prototype, so that the perimeter of the Strait of oil on the surface arrange a mound of waterproof material and fill it with water, and through the filters installed in the well above the lower limit of the distribution of petroleum products, pumps pumped to the surface of the oil-water mixture, where the share of petroleum products in edasimuujatega solutions and prototype allows to conclude that, the proposed technical solution meets the patentability criteria of “novelty.”

Patent scientific and technical literature for the specialist does not know the way in which the perimeter of the Strait oil arrange a mound of waterproof material and fill it with water, and from wells equipped with filters and pumps, pump oil-water mixture to the surface where it is separated into oil and water, to achieve the above effect.

Thus, the proposed solution meets the patentability criteria of “inventive step”.

The proposed solution can be used in various production sectors consumers of petroleum products and in case of emergency in the oil it will increase the efficiency of cleaning the surface from oil.

Thus, the proposed technical solution meets the criteria of the invention “industrial applicability”.

The essence of the method is illustrated in the drawing, which shows a schematic diagram cleanup.

Technological scheme includes barrow 1 of waterproof material, such as clay. Surface, limited bulk, filled with water 2. The oil rocks and the volume of petroleum products. Around the perimeter of the mound 1 construct the network odajnyk wells 4, equipped with filters 5 and by means of lifting water-oil mixture pump 6. On the surface is to install 7 for separating oil from water. The feed oil-water mixture in the installation of 7 is through the pipes 8 and diversion of clean water through the pipeline 9. The separated oil through the pipe 10 are removed in the tank.

The proposed cleaning method is implemented as follows.

After sizing the field of oil pollution of the surface and underlying rocks by known methods, for example by drilling wells around the perimeter of the distribution of petroleum products suit mound 1 of waterproof material, such as clay. Outside and inside of the embankment constructed a network of wells 4, equipped with filters 5 and pump 6.

When filling in the space inside the mound 1 water 2 due to the creation of excessive hydrostatic pressure oil is forced through the pores and cracks of the underlying rocks to working in otkacvam mode wells 4.

Pumped oil-water mixture through coarse filters through the pipes 8 is applied to the surface in the installation of 7 for the separation of water and is aprovado 9 to replace the water lost in space, limited in bulk 1. The process of leaching of petroleum products in the cleaning loop continues until the termination of the discovery of oil within the allowable concentration of oil pumped from wells 4 water in this type of soil.

The use of downhole systems for cleaning of contaminated or as a result of spills on the surface of the bedrock by creating excessive hydrostatic pressure on the surface formed inside of the waterproof rock embankments can effectively clean the surface and underlying rocks from spilled petroleum products.
