DEVICE FOR GAS-DYNAMIC RESEARCH OF GAS AND GAS-CONDENSATE WELLS Russian patent published in 1996 - IPC

FIELD: gas producing industry; applicable in control of operating conditions of development wells in development of gas and gas-condensate fields. SUBSTANCE: device for gas-dynamic research of gas and gas-condensate wells includes installed in the body units of preliminary and main gas cleaning, gas flowmeter and collectors of fluids and mechanical impurities. Preliminary cleaning unit has inlet blade swirling member, perforated protective casing in form truncated cone and plates attached to its external surface at some angle to longitudinal axis for rotation round this axis. Protective casing is installed with its small base of cone on the side of large base of cone of guide branch pipe. Unit of main gas cleaning has blade swirling member and cylinder filter element of perforated framework installed in perforated protective casing. Collectors of fluid and mechanical impurities are made in form of two vessels with check valves intercommunicated with each other and hollow of units of preliminary and main cleaning of gas through check valves. Vessels communicating with units hollows are made in form of cylinders coaxially arranged in each other, internal cylinder is made of metal lattice. Both vessels for collecting fluid and mechanical impurities and unit of preliminary cleaning are communicated with hollow of unit of main cleaning and both vessels of fluid and mechanical impurities collector of the unit of main cleaning are connected with hollow of device before gas flowmeter. EFFECT: higher operate reliability of the device and prevention of gas discharge to the atmosphere. 1 dwg
