摘要
基于17篇期刊文献综述了国内目前应用和研究的三大类油井近井地带解堵技术(不包括生物法),简介了各个技术的原理、优缺点及应用概况。第一类为化学法,包括常规酸液和各种缓速酸液处理法。第二类为物理法,包括蒸汽吞吐、电磁加热、多脉冲高能气体压裂、低频电脉冲、人工地震、高压水射流、水力振动、声波超声波及其他技术(层内燃烧和层内爆炸)。第三大类为物理化学法,包括热化学及各种联合解堵技术。参17。
Three classes of blockage removal technologies for treating near borehole zones of oil production wells, presently used and under study, are reviewed on the basis of 17 papers published （besides of microbiological ones as the 4th class）; their principles, advantages and disadvantages, and uses are presented. The 1st class, chemical treating technologies, covers standard and various retarded acids treatments. Physical treatments, such as steam huff-puff, electromagnetic heating, mutipulse high energy gas fracturing, low frequent electric pulsation, artificial earthquake, high pressure water jet, hydraulic oscilation, sonic-supersonic irradiation, and others （in-situ combustion and exploition） are introduced as 2nd class. The 3rd class is physiochemical technologies, including here thermochemical treatments and various, growing in number combinational treatments.
