- 气体水合物具有独特的物化性质，可以开发一系列高新应用技术。但是面临着生成速率慢、生成条件高、实际储气密度较理论值过低这一首要技术瓶颈，所有应用技术还停留在实验室研究阶段，当前最紧要的是研究水合物生成促进技术。实验采用CTAB、P123、［HMIPS］Ss几种新型添加剂作为水合物溶液的添加剂，测试不同温度、不同浓度下添加剂对水合物溶液表面张力的影响，以此判断这几类添加剂对水合物生成促进作用与表面张力的定量关系。研究发现其中降低表面张力效果最好的为300 mg/kg CTAB，然后依次为500 mg/kg P123、300 mg/kg［HMIPS］Ss。此研究为今后促进水合物生成研究提供了理论及数据支持。
The gas hydrate has unique physicochemical properties and a series of high-tech application technologies can be developed from the properties. However， all application technologies are still in laboratory investigation stage due to slow rate， high temperature and pressure conditions and low actual gas storage capacity during hydrate formation. Therefore， it is critical to study on the hydrate formation promotion technology. Test are effects of such new additives CTAB， P123 and Ss on hydrate solution surface tension in different temperature and concentration conditions and judged are quantitative relations of facilitation and surface tension of such additives in hydrate generation. Study results show that CTAB has the best effect in surface tension decrease （300mg/kg）， and then P123 （500mg/kg） and Ss （300mg/kg） in proper order. This study provides theoretical and data supports for future researches on hydrate generation promotion.
