COMPOSITE COMPOSITION FOR REMOVING STRATAL FLUID OF INCREASED RIGIDITY FROM LOW-YIELD GAS AND GAS-CONDENSATE FIELDS

摘要

FIELD: oil and gas industry.;SUBSTANCE: invention relates to production of gas and condensate of gas, namely to chemical reagents for stabilization of operation of low-yield gas and gas condensate fields, in products of which there is a reservoir fluid of increased rigidity – up to 40 mmole/dm³. Composition contains nonionic surfactant – surfactant alkyl dimethylamine oxide, amphoteric surfactant alkylamidopropyl betaine and cationic surfactant alkyltrimethylammonium chloride, in following ratio, wt%: alkyl dimethylamine oxide 80, alkylamidopropyl betaine 10, alkyltrimethylammonium chloride 10.;EFFECT: higher efficiency of removal of bottom-hole formation fluids from low-flow gas and gas condensate wells.;1 cl, 2 tbl
