高温高盐复杂油藏由于地层温度高,矿化度高,一般堵水剂的可泵时间和长期稳定性达不到使用要求。在实验室研究了一种适用于高温高矿化度复杂油藏深部调剖的凝胶调驱体系,该体系优于传统的凝胶体系,在高温高盐的复杂地层环境下达到了延缓交联和提高凝胶热稳定性的目的。
高溫高鹽複雜油藏由于地層溫度高,礦化度高,一般堵水劑的可泵時間和長期穩定性達不到使用要求。在實驗室研究瞭一種適用于高溫高礦化度複雜油藏深部調剖的凝膠調驅體繫,該體繫優于傳統的凝膠體繫,在高溫高鹽的複雜地層環境下達到瞭延緩交聯和提高凝膠熱穩定性的目的。

Due to high temperature and high salinity of complex formations,pumping time and long-term stability of general profile control agent is not up to the requirements of high-temperature and high-salinity reservoirs. A deep profile control gel system for high temperature and high salinity complex reservoirs was studied in the laboratory.Compared to conventional gel system,the system using in high-temperature and high-salinity complex formations environment can delay crosslinking and improve the thermal stability of gel.
