METHODS TO REMOVE A LEAKAGE IN FLOW TUBINGS OF GASAND GAS CONDENSATE WELLS

Abstract

It is proved that the offered methods for water shutoff and the annulus tightness recovery through delivery of water glass and sodium silicofluoride or solution of microdur R-U with sulfacyl to the leakage area will have a high efficiency in Cenomanian gas wells. It is demonstrated that these solutions possess a high power of penetrating into the pores and fractures, have good adhesion and strength characteristics at contacting with metal of the production tubing and surrounding rocks.
