TUBE SEPARATOR, INSTALLATION AND METHOD OF SEPARATING OIL, GAS AND WATER AT EXTRACTION AND PRODUCTION OF OIL Russian patent published in 2009 - IPC E21B43/36 

FIELD: oil and gas industry.

SUBSTANCE: group of inventions refers to separation of oil, gas and water at extraction and production of oil and gas from deposits under sea bottom. Separator consists of a lengthy tube case with input and output ends; diametre of the case at output and input ends is either equal or slightly bigger, than the diametre of the transporting tube whereto the case of the separator is attached. Further, the separator consists of electro-static coagulator made in form of a tube. Also the coagulator includes electrodes made so, that by means of electric voltage supplied to them electrostatic field is generated inside the tube. According to the invention the electrostatic coagulator is combined with the case of the separator, creates with the latter an integral unit and is installed at a distance from the input, where preliminary separation of oil and water occurs. The coagulator has upper and lower electrodes. The installation for separation contains the above said separator and cyclone. The method of separation provides implementation of the above said separator.

EFFECT: increased efficiency of the method and increased reliability of installation operation.
