摘要
低渗透油藏存在着很多问题,最为明显的则是注水压力高,配注不符合要求,针对此很多油田开始实施了表面活性剂增注技术的试验,旨在改善不良情况,优化油井注水,进而保证油藏开采质量。本文从杂双子表面活性剂增注技术的优势谈起,详细阐述了杂双子表面活性剂增注技术在低渗透油藏中的具体应用,并对试验结果做详细分析,为今后的油田开采工作中积累更多经验。
There are many problems in low permeability reservoirs,the most obvious one is that the injection pressure is high and the injection allocation does not meet the requirements.For this reason,many oilfields began to carry out the experiment of surfactant Injection Enhancement Technology in order to improve the bad situation,optimize the injection of oil wells,and ensure the quality of reservoir production.Starting from the advantages of heterogenous surfactant injection technology,this paper elaborates the specific application of heterogenous surfactant injection technology in low permeability reservoirs,and makes a detailed analysis of the test results in order to accumulate more experience for future oil field production.
