| titleOfInvention | High-temperature resistant steam chemical auxiliary agent for thermal oil recovery |
| abstract | The invention provides a novel high-temperature resistant steam chemical auxiliary agent for thermal oil recovery. The novel high-temperature resistant steam chemical auxiliary agent comprises 65-85% a high-temperature resistant poly fatty acid acylamino alkyl dimethyl tertiary amine non-ionic surface active agent and 15-35%a mutual solvent in terms of percentage by weight. The technical bottleneck that the chemical oil displacing agent in the prior art cannot be used at high temperature is overcome; the steam chemical auxiliary agent disclosed by the invention can have high stability and oil displacing performance in the steam atmosphere being up to 350 DEG C; therefore, chemical displacement and steam displacement are combined perfectly and organically; the oil recovery cost is favorably reduced; and the thermal oil displacing recovery rate is increased. |
