PLANT FOR TEMPERATURE DETERMINATION OF OIL SATURATION WITH PARAFFIN Russian patent published in 2000 - IPC

FIELD: oil-producing industry. SUBSTANCE: plant is designed for determination of physical parameters of formation fluids and consists of high-pressure chamber placed in thermostat with thermometer. Located in high-pressure chamber are optical glasses. Connected to lower part of high-pressure chamber is flexible light guide which is coupled with its other end to photosensor. For introduction of oil sample into plant, needle valve with pipeline is connected from left side of high-pressure chamber. Oil sample is placed between optical glasses. Thermocouple is joined with its one end to high-pressure chamber from its right side and with its other end it is placed in flask filled with liquid nitrogen, also from right side of high-pressure chamber. Measuring valve with its one end is connected by means of pipeline for measuring press with rod and pressure gage. Connected to press with the help of pipeline is needle valve for sample withdrawal. Upper part of high-pressure chamber is connected with illuminator provided with a set of lenses. Illuminator, thermocouple and photosensor are connected with generator-switch which is joined to recording potentiometer. EFFECT: higher accuracy of determination due to changing of plant design. 1 dwg
