DEVICE FOR COLLECTING OIL Russian patent published in 2017 - IPC E21B43/34 

FIELD: oil and gas industry.

SUBSTANCE: device for collecting oil contains a housing with branch pipes for gas-liquid mixture input and oil output, a branch pipe for gas output, all pipes equipped with a stop valve, a branch pipe for water and slurry output; a drop catcher is installed in the upper part of the housing, and guide planes of the gas-liquid mixture flow are installed inside. The housing represents a thermally insulated container, the inner surface of which consists of a cylindrical portion, a conical hydrocyclone and a water and sludge collection chamber. In the upper part of the housing there is a drop separator with concentric openings covered with conical bumpers. In the hemispherical housing of the drop catcher, a pressure sensor is installed and a set of vertical blades equipped with grooves for collecting liquid and a tray connected to the drainage pipe with the outlet to the sludge collection chamber is arranged. The drop separator is additionally equipped with an ejector connected via a pneumatically actuated valve with a main compressed air supply line and a diffuser connected via the pneumatically actuated valve with the main line for supplying compressed air to the collecting pipeline of the low-boiling fractions condensate. A density sensor is installed on the cylindrical section of the housing, and a density sensor and a valve with pneumatic actuator connected to the compressed air pipeline are installed in series on the outlet branch pipe connected to the heat-insulated oil collection pipeline.

EFFECT: increasing hydrocarbon production, improving the working conditions and normalizing the microclimatic parameters of the mine atmosphere, reducing the content of toxic gases and hydrocarbon vapours in the air of drilling galleries.
