摘要
采用Waring Blender法对LD32-2油田氮气泡沫压锥体系的起泡剂的起泡性、稳泡性及其与地层水的配伍性进行了研究。静态试验结果表明,起泡剂浓度、地层水矿化度、原油含量及温度等因素对体系性能具有重要影响。起泡剂QP-1和QP-4具有良好的耐温抗盐性和耐油性能,其最佳使用含量为0.5%。
The foamability and foam stability of the nitrogen foaming agent system for suppressing water coning in LD32-2 Oilfield as well as its compatibility with formation water were studied with Waring Blender.According to results of static test,the concentration of foaming agent,the salinity of formation water,the content of crude oil and the temperature,etc.affect the properties of this foaming agent system significantly.Both foaming agents QP-1 and QP-4 have good good high-temperature resistant,salt resistant and oil resistant performance,and their optimum content for use is 0.5% each.
