FIELD: gas and oil production industry.
SUBSTANCE: invention relates to chemical composition used in treatment of holes, among them, absorbing holes, for decreasing the content of hydrogen sulfide in gaseous space in carrying out repairing, research and other works, and can be used in gas and oil production industry under conditions of normal and low seam pressures. Proposed composition comprises the following components, wt.-%: sodium peroxocarbonate, 10-40; surfactant (surface-active substance), 0.5-10; polyacrylamide, 0.02-0.1; sulfamic acid, 17-53, and sodium nitrite, 21-52. The slid-phase composition can comprise water glass also. Invention provides development of effective and simple in preparing and technological composition used for neutralization of hydrogen sulfide in holes.
EFFECT: improved and valuable properties of composition.
