Description

Foam scrubbing agent composition for salt-resistant acid-resistant water drainage and gas production and preparation method and application thereof
Technical Field
The invention relates to a foam scrubbing agent composition for salt-tolerant acid-tolerant water-draining gas production, a preparation method and application thereof, and belongs to the technical field of oil-gas field chemical agents.
Background
With the enhancement of the exploitation strength of the gas field, the water output of the gas field becomes a key problem restricting the normal production of the gas well. Foam drainage gas production is a drainage gas production technology which is rapidly developed at home and abroad in recent years, and has the advantages of simple equipment, convenience in construction, low cost, wide applicable well depth range, no influence on normal production of gas wells and the like. The foam drainage is characterized in that a surfactant with special functions is introduced into mineralized water at the bottom of a well, so that a large amount of low-density water-containing foam is generated in the process of gas-liquid two-phase mixing and vertical flowing, the foam carries water along with air flow from the bottom of the well to the ground, the gas-liquid vertical liquid lifting capacity is improved, and the purpose of drainage and gas recovery is achieved. Some gas fields not only have high mineralization degree, but also are acidic due to the existence of acid gas, so that the foaming capacity and stability of the foam discharging agent are greatly reduced, and the effect of water discharging and gas production cannot be achieved. Therefore, it is required to develop an acid-resistant salt-resistant foam discharging agent with high foaming efficiency.
At present, the foaming agent for water drainage and gas production mostly adopts a multi-component compound system and simultaneously comprises a non-ionic surfactant and an ionic surfactant. In order to enhance the stability of a single foam, an auxiliary agent such as alkali, alcohol, polymer, alkanolamide and the like is usually added into the formula to form a reinforced foam. Patent CN102212344A discloses a high-temperature foam discharging agent for drainage and gas production, which comprises the following components in parts by mass: 10-15 parts of sodium dodecyl sulfate, 2-5 parts of alkyl glycoside, 15-18 parts of AES, 20-25 parts of sodium dodecyl sulfate, 5-10 parts of biosurfactant and 27-48 parts of water, and the salt resistance of the composite is poor. US20120279715 reports a foam fluid for increasing oil yield by recovering gas in a gas well, which is an amido group-containing quaternary ammonium salt surfactant having foam discharging and sterilizing functions, and a hydrophobic chain is a hydrophobic segment in substituted naphthalene ring, benzene ring or natural oil ester, so that the foam fluid has strong chlorine resistance and condensate oil resistance, and also has good corrosion inhibition performance. However, since the molecular structure contains an amide group which is sensitive to high temperature, the compound is easily hydrolyzed under acidic conditions.
