RAW OIL AND GAS INVESTIGATION PLANT Russian patent published in 2007 - IPC E21B49/08 G01N7/14 F04B23/00 

FIELD: oil and gas production, particularly equipment for oil and gas property investigation under reservoir conditions.

SUBSTANCE: plant comprises piston container with plug and transfer unit, which moves sample from piston container into measuring press including two piston pumps having equal capacities. One piston pump delivers sample from piston container, another one lowers floating piston in measuring press. Measuring press is provided with floating piston having hollow shaft, ultrasonic linear displacement sensor for oil volume determination and electronic linear displacement sensor for gas volume determination. Circulation piston pump provides unidirectional oil circulation at controllable rate. Viscosimeter has bypass with shutoff valve. Single thermostating shell encloses all components of the plant.

EFFECT: increased accuracy of oil and gas volume and viscosity determination, decreased sample characteristic measurement time under reservoir conditions and, as a result, increased operational efficiency.
