Abstract
A gas trap used to separate at least a portion of the gases entrained in drilling fluids used in an oil well drilling operation which is associated with the shale shaker box and an analyzer such as a hot wire analyzer. The gas trap includes a receptacle or can vertically adjustably supported from the shaker box by a supporting assembly with the can including a top supporting the can by a unique connecting assembly enabling rotational adjustment of the can about a vertical axis to orient the inlet and outlet from the can in a desired location in relation to the shaker box. The top is provided with a standpipe and a motor shaft extends through the top and is provided with plastic fingers radiating from the lower end thereof for agitating the drilling fluid to assist in gas removal.
Claims7
A gas trap for removing, collecting and discharging gases from a drilling fluid whereby a portion of the gases may be analyzed, said gas trap comprising a generally vertically disposed can having a bottom inlet and a side outlet for drilling fluid, a shaft depending into the can and drivingly connected to a motor disposed above the can, a plurality of radially extending fingers on the shaft in engagement with drilling fluid to agitate the drilling fluid and facilitate separation of gases therefrom, said can including a top member closing the upper end thereof with the shaft extending centrally therethrough, a standpipe communicated with the interior of the can through the top member to subject the interior of the can to a vacuum and discharge gases collected in the can to an analyzer, means connecting the can to the top member in a secure but releasable manner to enable the can to be rotated about a vertical axis in order to orient the side outlet in desired angular relationship about the center of the can and means supporting the top member and the can, standpipe, motor and shaft in desired vertical relationship to the surface of a drilling fluid.
