Abstract

The invention relates to a preparation method of an over-stable polyphase foam system, and especially relates to an environmentally friendly over-stable polyphase foam system and a preparation method thereof. The foam system contains a biotype surfactant alkyl glucoside, a cationic gemini surfactant and silica nanoparticles, and the cationic gemini surfactant is C12-3-C12.2Br. The foam system has the advantages of good biocompatibility, good ecologic safety, great improvement of the foam stability, easy dispersion in the system by using hydrophilic nanometer, and easy preparation of foams. Only a very small amount of the cationic surfactant is needed by using the surfactant compounded system to foam, and the biotype surfactant alkyl glycoside massively used in the system are cheap and easily available.

Description

technical field

[0001] The invention relates to a preparation method of an ultra-stable multi-phase foam system, in particular to an environment-friendly ultra-stable multi-phase foam system and a preparation method thereof. Background technique

[0002] Foam fluid has the advantages of adjustable density, good compressibility, high viscosity, small frictional resistance, small amount of liquid, little damage to the reservoir, and strong solid particle carrying capacity. It is widely used in various process links of the petroleum industry, such as acidification, compression Cracking, plugging removal, water pressure cone, control and flooding, etc. Foaming agents used in foam systems are generally anionic surface or nonionic surfactants, and foam stabilizing aids are polymers such as polyacrylamide. The currently used alkylbenzene sulfonic acid or α-olefin sulfonate surfactants have great environmental protection pressure due to their poor environmental friendliness and deg...
