| titleOfInvention | High-salinity-resistant foam scrubbing agent composition for drainage and gas recovery and preparation method and application thereof |
| abstract | The invention relates to a foam scrubbing agent composition for hypersalinity-resistant drainage and gas production, and a preparation method and application thereof. The method mainly solves the problem that the gas well has reduced production and even stops spraying due to excessive liquid loading in the development process of the existing gas well. Comprises the following components by adopting a mole fraction meter: (1)1 part of long-chain polyether nitrogen-containing compound; (2) 0.5-20 parts of olefin sulfonate; wherein the long-chain polyether nitrogen-containing compound has a molecular general formula shown in formula (I), and R is 1 Is C 8 ～C 30 The fatty group of (a); y is the sum of PO segments; z is the sum of EO segments; r 2 Is C 1 ～C 4 An alkylene group of (a); r 3 、R 4 Is C 1 ～C 5 The technical scheme of any one of the alkyl and the substituted alkyl better solves the problem. Can be used for water drainage and gas recovery in high-salt gas fields. |
