WELL SURVEYING FACILITY Russian patent published in 2011 - IPC E21B47/00 E21B43/00 

FIELD: mining.

SUBSTANCE: well surveying facility includes product receiving line of the surveyed well and is equipped with pressure controls, pressure and temperature measurement devices, vertical gravitational separator for separation of gas from liquid. Gravitational separator is equipped with condensate and water extraction lines, as well as interconnected by means of pressure controls, automatic valves and check valves with condensate collector provided with liquid level gauges. Facility is also equipped with heat exchanger installed upstream of vertical gravitational separator. In addition, well surveying facility is equipped with high pressure gas supply line connected with small-size wave expansion machine. Compressor part of wave expansion machine is connected to heat exchanger installed downstream of vertical gravitational separator. In addition, heat exchanger is connected to heat exchanger the outlet of which is connected to gas extraction line to industrial chromatograph, and through the protection capacity of chromatograph with float liquid level sensor. At that, industrial chromatograph is connected to controller and personal computer.

EFFECT: improving accuracy and reliability of field gas-condensate well surveys owing to separation gas temperature reduction; excluding gas and condensate losses due to combustion on flames; considerable increase of scopes of surveys owing to reducing the labour intensity.
