Detailed description of the invention
Below with reference to the accompanying drawings the detailed description of the invention of patent of the present invention is described in detail.
In patent of the present invention, comprise that for oil gas field individual well gas circulation treating apparatus gas divided gas flow processor 2, gas circulator 3 and operation tank 4 are connected successively along the direction of motion of gas.
Gas separator 1, its import 5 is connected with oil gas field production flow line, and import department adopts and tangentially enters, and gas outlet 6, equipment upper end is connected with gas processer, and bottom is directly installed on operation tank 4.Gas separator 1 adopts draw ratio to be greater than and in 4 the vertical cylindrical shell of vertical tubular construction, is provided with devices such as separating umbrella crown, mist eliminator.After the tangential access to plant of individual well gas-liquid mixture, utilize the stop centrifugation of multicomponent from the device such as umbrella crown, mist eliminator, and the Gravity Separation of oil gas, isolated gas enters into gas processer by gas outlet, top, and the isolated crude oil that contains a small amount of natural gas and water directly enter into operation tank 4.
