PROCEDURE FOR COMPLETION AND OPERATION OF GAS WELL Russian patent published in 2011 - IPC E21B43/00 

Abstract RU 2423602 C1

FIELD: oil and gas production.

SUBSTANCE: procedure consists in cementing producer, in lowering production string to roof of pay, in replacing drill agent with fluid of less density, in perforating lower exposed interval of pay, in successive completion of well, and in perforating rest part of pay in gas medium. Before lowering a coupling-choke with a through orifice is screwed on the end of the last pipe of the production string. After perforation of whole production core and for well operation a removable plastic shank end of specified length is lowered into the well on a cable through the orifice in the coupling-choke. The shank end is suspended in the coupling-choke. During current well survey the removable shank end is extracted from the well for time of survey a metal ring for lowering and lifting the shank end is arranged on internal surface in an upper part of it; there is used an electro-magnetic device on the cable the same, as during fishing operations. In case length of the removable shank end exceeds internal dimension of a traditional metal oil cup, then one more or more removable shank end is lowered for the period of well operation.

EFFECT: high efficiency and normal operation of well at withdrawal of mechanical impurities, seam or condensation water and condensate.
