Results of comparative corrosion tests of a cement stone samples in tap water and formation one with the content of salts of sodium, calcium and magnesium chlorides are given. Backfill compositions of various density (lightened, weighted and normal density), with various additives (blast-furnace slag, clay, bergmeal etc.), applied at wells casing, are tested.
