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

FIELD: development of gas and gas-condensate deposit by wells. SUBSTANCE: method for gas-dynamic research of gas and gas-condensate wells includes separation on the wellhead, at several steady conditions, of well products, measurement of production rate of gas and other solid and liquid phases, taking samples of phases and their analyzing. Research is continued up to stabilization of all measured parameters and gas is supplied to gas collection point of its treatment. The device for the method embodiment includes units for preliminary and main cleaning of gas with swirlers installed in body, gas flowmeter with diaphragm, pressure and temperature measuring units, collectors of fluid and mechanical impurities. Unit for preliminary cleaning has protective casing and branch pipe-baffle and the unit of the main cleaning of gas has cylindrical filtering element on perforated frame. Unit for the main cleaning of gas is connected with gas flowmeter by means of central outlet cylindrical pipe which form channel together with perforated frame running to diaphragm and equalling 12 channel diameters. Body and unit members accommodated inside it are detachable. EFFECT: higher efficiency. 2 cl, 3 dwg
