METHOD AND EJECTING DEVICE FOR OPERATION OF CLUSTERED GAS WELLS Russian patent published in 1998 - IPC

FIELD: gas production industry. SUBSTANCE: this relates to intensification of gas recovery from wells and ensures increased total output of gas wells of various productive capacity at minimal spending of gas bed energy. According to method, connection of low-output well and high-output well is effected with help of their contours. This is performed through ejector. Operation of wells is carried out with ejection of low-pressure gas by high-pressure gas. In this case, wells are additionally connected according to by-pass scheme. Performed is stabilization of pressure in contours. Pressure at well head is fixed. After that, wells are switched from by-pass scheme of operation to ejector operation and additional depression is created at bottom-hole of low-output well. Additional depression is obtained so as to ensure pressure differential in contours at inlet to ejecting device not over 5% of its nominal values. Device for realization of aforesaid method has receiving chamber and mixing chamber with contraction. Receiving chamber is made with tangential inlet, nozzle which is located inside, and narrowing tapered component. This components creates intermediate chamber inside receiving chamber. Intermediate chamber is connected with diffuser. All this is made for possible dispersing of liquid which accompanies gas. EFFECT: higher efficiency. 1 cl, 2 dwg
