摘要
针对鄯善油田低孔、低渗、低温特点,在注水开发过程中容易出现混合堵塞,研究并应用了复合活性物解堵技术。该技术利用多种高效表面活性剂、无机化合物复配,能综合处理近井地带的油层污染。现场应用结果表明,该技术具有见效快、增产效果显著的特点。
The reservoir in Shanshan oilfield is characterized by low porosity,low permeability and low temperature. Mixed plugging is easy to occur during water injection.Plug removal technique with compound active material is studied and applied.Using multiple high-effective surface acting agent and inorganic compound combination can handle the reservoir pollution near wellbore.The application results show that the technique has quick effectiveness and obvious effect in production increase.
