METHOD OF PUMPING OUT GELATED OIL PRODUCTS FROM CLOSED RESERVOIRS Russian patent published in 2005 - IPC

FIELD: environmental protection.

SUBSTANCE: invention can be used at emergency situations for collecting oil and oil components by discrete or stationary withdrawal of considerable layers of oil field. According to proposed method, oil is heated by head carrier which is essentially heated oil placed inside closed reservoir. Design of rectangular siphon containing at least two chambers and fitted-on cables and hydraulic carriers of closed feed system improves process of pumping out, mixing of oil layer with oil heated in process of pumping out with use of agitator interacting with cables. Economic efficiency of method lies in possibility of scheduled repair operations inside large-size reservoirs capable at preservation of worn-out pipelines to cut down time of access to worn-out or damage walls of oil-filling reservoirs in process of preparation for preventive repair.

EFFECT: improved technological capabilities.
