河南油田聚表剂性能评价

Performance Evaluation on Polymer Surfactant in Henan Oilfield

针对河南油田Ⅲ类及以上油藏提高原油采收率的需要,通过对聚表剂基本质量性能、长期热氧稳定性、耐温抗盐性能、乳化携油能力、岩心驱油效率等进行系统评价,优选出聚表剂JBL-1。当JBL-1质量浓度为2 000 mg/L、段塞量为0.5 PV时,能提高采收率16.49%。

In view of the need for increasing oil recovery from the oil reservoirs of Class Ⅲ or above in Henan Oilfield, a polymer surfactant named JBL - 1 was chosen through a systematic evaluation on the basic quality, long - term thermal oxidative stability, heat resistant and salt tolerant property, emulsifying and oil - carrying capacity and the efficiency of oil displacement in cores, etc. of polymer surfactants. Recovery efficiency can be increased by 16.49% when the mass concentration of JBL - 1 is 2 000 mg/L and the slug size is 0.5 PV.
