The article describes the problem of discharge and disposal of wastewater produced in the technological methods of drilling offshore wells. Wastewater drilling water into the sea is prohibited in Russia, even after purification, because to achieve a complete cleaning in a marine environment is very difficult and expensive. It’s offered to clean drilling wastewater to a state that allows them to reuse in the drilling process. This article discusses the three most common and effective ways to pre-treatment. Physical and chemical method of coagulation formation for impurities deposited further flakes. Electric electro coagulation method suggests the using of electric fields for the polarization and the interaction between a charged particle with their subsequent removal. Mechanical method suggests the using of the centrifugal forces arising in the hydrocyclone. When using the latter method for improving cleaning efficiency hydrocyclone successively collected to the battery.
