摘要
为了更好地推广和应用新型纳米微球逐级深部调剖技术,对该技术的主体纳米微球的粒径大小影响因素进行了研究。结果表明,适量的矿化度有助于微球的溶胀,Ca2+和Mg2+的存在会抑制微球溶胀,适宜的p H值有助于微球的溶胀,温度越高纳米球体系的膨胀速度越快。
In order to promoting the popularization and application of the new type of nanometer microspheres by deep profile control technology, we studied the influence factors of nanometer microspheres particle size. The results showed that the appropriate salinity conduced to the swelling of the microspheres, on the contrary, the exis-tence of Ca^2＋and Mg^2＋could inhibit the swelling of the microspheres. Appropriate p H value was helpful to the swelling of microspheres and the expansion velocity of the nanometer microspheres increased with the increase in the temperature.
