For example, chinese patent application CN107603581A discloses a foam drainage agent composition, a preparation method and an application thereof, belonging to the technical field of petrochemical industry. The efficient foam water draining agent composition comprises the following components in parts by weight: 1 part of alkylamine polyether benzene sulfonate and 0.1-50 parts of long-chain polyether nitrogen-containing compound. By adopting the technical scheme of the invention, according to SY/T6465-2000 evaluation method for foam-generating agent for water drainage and gas production, foam performance test is carried out on the foam drainage agent, the foam height is more than 200mm, the liquid carrying amount is more than 150mL, aging is carried out for 24 hours at the high temperature of 180 ℃ in mineralization saline water of 0-200,000 mg/L, the foam height and the drainage performance change rate are less than 5%, and the foam drainage agent has good temperature resistance, salt resistance, foaming performance and liquid carrying capacity, and obtains good technical effects, but the cost is relatively high, the anti-condensation oil capability is not embodied, and the foam drainage agent can not be simultaneously adapted to the environments under multiple conditions of high temperature, high condensation oil content, high calcium and magnesium ion concentration and the like.
For another example, chinese patent application CN108251091A discloses an anti-mineralization and anti-condensate liquid foaming agent and a preparation method thereof, which comprises the following raw materials by mass percent: 70 to 90 percent of cocamidopropyl amine oxide; anionic surfactant: 5% -20%; 3 to 10 percent of cationic surfactant. The salinity and condensate oil resistant liquid foaming agent can effectively resist the influence of salinity and condensate oil on the foaming agent, realize normal foaming and liquid carrying, and improve the foam drainage and gas production effects, but has relatively poor foam stabilizing capability and liquid carrying capability, cannot carry liquid normally under the condition of low gas well pressure, cannot improve the exploitation efficiency well, and simultaneously has large usage amount and relatively high use cost, and cannot adapt to the environments with multiple conditions of high temperature, high condensate oil content, high calcium and magnesium ion concentration and the like.
