Methane Hydrates and Related Phenomena

During the development of the oil and gas complex in conditions of Western Siberia the acute problem raises with the bore mud recultivation. The amount of mud storage pits in Khanty-Mansiisk autonomous district reaches three thousand, analogous situation is also in YNAO. The bore muds have negative physical and chemical properties, such as ash structure, high dispersion, absence of airing, weak filtration, swelling ability, hydrophilic nature, high alkalinity and toxicity. The indicated properties are stipulated by the presence of water-soluble salts in the original soils and addition of caustic soda and soda ash into the bore muds and the following introduction of sodium into absorbing complex. The studies showed that this problem can be solved at the expense of use of phosphogypsumcoagulant which is chemical waste in combination of magnetic water. This contributes to the increase of filterability by 35.8 times and flow-outs of water-soluble salts. This phenomenon will allow us to create favorable conditions for the cultures-phytoameliorants during the following recultivation.
