耐温耐盐调驱体系NHTP的评价及应用

Evaluation and Application of Profile Control and Oil Displacement System NHTP with High-temperature and High-salinity Resistance

介绍了一种新的耐温调驱剂体系NHTP．并对该耐温调驱剂的调驱性能进行了评价。评价结果表明，该调驱体系在130℃以下、矿化度小于100000mg／L环境中具有稳定的成胶性能，成胶时间介于8-15h之间，成胶强度大于21000mPa·s。5口井现场试验结果表明NHTP对中高低渗及大孔道油藏均具有良好的堵塞性，在高温油藏调驱领域具有良好的应用前景。

A profile control oil displacement system NHTP is introduced, and its performance is evaluated. The results show that the system has stable gelling property under lower than 130℃ and less than the salinity of 100 000mg/L, gelling time is 8-15h, and gelling viscosity is greater than 21 000mPa. s. The field tests of 5 wells show that NHTP system can effectively block the large pores in heterogeneous reservoirs, and has good high-temperature and high-salinity resistance.
