In order to test stability of ZS-5 under the conditions of high temperature and high salinity, the largest oil resistance and temperature resistance were tested using the Waring Blender mediod.The results showed that ① foam volume of ZS-5 was able to maintain between 950 mL and 1100 mL with oil content of 5％ ～ 15％ , which express a strong stability; half-life analysis of liquid in different oil content was declined, but it still reached 45 min under the condition of oil content more than 15％ ;② foam volume of ZS-5 was bigger than the volume which tested at room temperature after rising temperature; a trend increased first and then decreased, half-life analysis of liquid at different temperatures was declined, but it still maintained about 20 min at 95 ℃, which show a good value of use.%为了检测ZS-5新型复合驱配方,在高温高矿化度油藏条件下的稳定性,用Waring Blender法对其最大的耐油性和耐温性进行了检测.结果表明:①ZS-S在原油加量5%～15%下,泡沫体积仍然维持在950～1 100 mL之间,起泡性较好;析液半衰期随原油加量增高有所下降,但含油量15%条件下仍在45 min以上,稳定性较好;②升高温度后,ZS-5的泡沫体积大于常温下所测体积,总体上呈现先增后减小趋势,体现了较好起泡能力;析液半衰期随温度升高逐渐减小,但在95℃时,仍能保持在20 min左右,具有较高使用价值.
