摘　　要：水平井技术作为油田提高采收率的重要手段,在国内外得到广泛应用,但是随着开发的延续,高含水已成为制约水平井高效开发和油田稳产的主要问题。而常规的化学堵水剂受油藏条件和水平井完井方式的双重制约,无法满足塔河油田水平井堵水的施工需要。为此,我们研制了YN-1液凝堵水剂,并进行了室内研究和效果评价。结果表明,该体系耐温抗盐,具有良好的注入性,在高温下稳定时间长,在高温高盐油藏具有广阔的应用前景。horizontal well is an important method of EOR,which has been extensively used at home and abroad.Along with continual exploittation of Oil field,high water-cut has been the principal problem which highly restricts efficient development on horizontal well and dependable production in Oil field.The use of Conventional Water Shutoff agent is confined by reservoir and well completion type.Therefore,we have invented YN-1 fluid gelling blocking agent.A lot of experiments and effectiveness evaluation have been done.Results indicate the system has properties of heat resistant,salt toleran,pour easily and long stabilization time,hence its application prospects would be great for reservoir with high temperature and high salinity.
