DEVICE FOR DRILLING AGENT DEGASSING Russian patent published in 2011 - IPC E21B21/06 

FIELD: oil and gas production.

SUBSTANCE: device for drilling agent degassing consists of degassing chamber, of its cover, of float and of aerator. The degassing chamber is made as vertically elongated structure and consists of two coaxial vertically oriented pipes of different diameters: an upper one - of bigger diameter and a lower one - of smaller diameter. On a lower end of the lower pipe there is present non-uniformity in shape of meander around circumference in section of the end part of the lower pipe. The aerator is positioned inside the lower pipe from the lower end and has diameter less, than diameter of the lower pipe. The cover of the degassing chamber has four ports for release of excess pressure, for sampling of analysed product, for connection with an inlet of a compressor and for connection to the channel for the aerator.

EFFECT: reduced weight and dimension at reduced cost and expanded functionality of implementation under various conditions including reservoirs of drilling rigs of low capacity.
