Abstract
The problem of maintaining tightness of tubing annulus in gas and gas condensate reservoirs is especially urgent. Leakiness is caused by the fact that formation fluid in such reservoirs often contains aggressive components - hydrogen sulfide, carbon dioxide, as well as poor insulation of formations containing these agents. This leads to various complications during well operation.
