DRILL CUTTINGS DRYING SYSTEM AND METHOD Russian patent published in 2016 - IPC E21B21/06 

FIELD: oil and gas industry.

SUBSTANCE: group of inventions relates to oil and gas producing industry, in particular, to treatment of drill fluids used as well-drilling. The device includes the first fluid collection system for functional layout under filter of vibrating shale shaker and carrier system for drilling fluid collection from the first shaker filter section and carrier system, the second system for drilling fluid collection intended to be connected at modification to the shale shaker. The second system includes extension of the filter and filter coupled functionally to the filter of vibrating shale shaker and carrier system protruded outside limits of the initial length of the filter of vibrating shale shaker and carrier system, and vacuum system functionally coupled to the reverse side of the filter extension in order to impact the filter extension by vacuum pressure and to collect drilling fluid from it.

EFFECT: improved treatment efficiency within wide range of filter cell sizes, consumption of vacuum pressure and design of the vacuum system.
