Abstract
With the discovery of deeper gas reservoirs, influential factors such as deeply buried depth, high geothermal gra-dient, and formation water yield have greatly affected the normal production of gas wells during the intermediary and later stage, even at the early stage of gas reservoir development. All these effects have greatly reduced the ultimate recovery factor. According to the characteristics of this type of reservoir, effects of temperature on the performance of drainage agent were pres-ented in aspects of foam stability, surfactant foamability and surfactant micelle aggregation. It is found that temperature mainly influences foamability, stability and the molecular structure of the main surfactant. It is pointed out that good foam drainage a-gent under high temperature is ionic surfactant with good thermodynamic stability, low superficial tension, hydrophilic radical in the middle of molecule chain as far as possible and molecular weight not too high. A new foam drainage agent, KFSY, which is suitable to high temperature, has been developed and experimental results have also proved that KFSY has good foamablity and stability under high temperature.关键词
