| 摘 要： | 在室内测定了不同的聚丙烯酰胺质量分数和相对分子质量、地层渗透率、温度、矿化度等条件下铬冻胶堵剂的突破压力 ,对各因素影响铬冻胶堵剂突破压力的原理进行了简单分析。结果表明 ,堵剂的突破压力值随聚丙烯酰胺质量分数和相对分子质量以及温度的增加而增加 ,随渗透率增加而减小。铬冻胶堵剂的突破压力与注入水矿化度之间并不存在规律性的关系 ,只是在矿化度为 10 g/L时突破压力有最大值。

| Abstract: | The breakthrough pressure of chromic gel was measured under the conditions of the different concentrations, molecular weights of polyarylamide (PAM), and variable permeability, temperature, salinity of the injected water. The influencing mechanism of the different factors for the breakthrough pressure was discussed. The results show that the breakthrough pressure gets stronger with the increase of PAM concentration, molecular weight of PAM and the temperature, and it is reduced with the increase of formation permeability. The breakthrough pressure of chromic gel has no any regular relation with the salinity of the injected water. However, the breakthrough pressure may reach the highest value when the salinity of the injected water is ten grams per liter. |
