Sludge is the sediment. Drilling and oil sludge

In a literal translation from the German language this word means – dirt. Sludge – the precipitate solid fine particles, which is formed by filtration or settling any liquid. In addition, it may be powder formed during the electrolysis of metals. As a rule, such sludge contains microparticles of noble metals. Finally, the cuttings produced by the drilling or crushing rock.

Drilling mud

This kind is an aqueous suspension. It has a solid part, consisting of products resulting in the destruction of rocks and the walls of the well. Drill cuttings – part of the suspension, which picks up the slurry pipe in the process of core drilling. Drill cuttings includes four types of waste:

- bentonite waste;

- clay

- liquid ground;

- the ground water.

It is Very important to properly dispose of drill cuttings. It is a task the solution of which depends the welfare of the environment. Today there are several methods of disposal, but until now experts did not come to a consensus which one is more efficient.

Oil sludge

This is a stable, multi-component system. It consists of petroleum, water and mineral admixtures. Oil sludge – is a product that is formed during extraction, processing and transportation of crude oil.

Types of oil sludge

In accordance with the condition of the sludge, they can be divided into three separate groups:

1) groundwater, which are formed in the case where crude oil or petroleum products spilled on the ground (in production or in emergency situations);

2) reservoir - formed by the transportation of petroleum products or during their storage in tanks of different designs.

3) bottom - this type of sludge may occur if oil spill deposited on the bottom of the pond.

In a separate group allocate the sludge generated during oil production. Facing the surface of the earth an oily flammable liquid in its composition contains fine particles of salt and rocks, water, gases. This so-called crude oil. The impurities contained in it, seriously hampering transportation and processing of crude oil. Therefore, pre-raw kaustobiolit is processed in a special way. It is removed from the water, mechanical impurities, salts and solid hydrocarbons. Then in the oil reservoir is again pumped the water (to maintain pressure). As a result of mechanical impurities from the oil be oil sludge.

Currently, the processing of the substances mentioned – it is a necessary process. Thanks to him, it is possible to recover some oil. Oil sludge, regardless of the nature of occurrence, harmful to the environment.

To date, the only method of disposal-the incineration or landfilling. These methods are very costly in financial terms, require strict compliance with all technological norms. But they do not give the desired result.

Yes, unfortunately, the ideal method of disposal of oil sludge has not been found yet. As in the twentieth century, often using traditional methods – burning, settling, filtration.
