到目前为止一直未对高温花岗岩基底储层堵水扫油效率作过充分的研究。我们在高温下试验了多种聚丙烯酰胺化合物与有机、无机交联剂的稳定性 ,对温度、聚合物、交联剂、矿化度和pH值对凝胶作用和稳定性的影响进行了研究。 Up to now, sufficient research has not been done on the water blocking and sweeping efficiency of high temperature granite basement reservoirs. We tested the stability of various polyacrylamide compounds with organic and inorganic crosslinkers at elevated temperatures under the influence of temperature, polymer, cross-linker, degree of salinity and pH on gel action and stability the study.
