摘要

目前没有针对纳米封堵剂封堵效果评价的方法。在室内进行评价时,实验结果往往会无法反映出纳米颗粒的封堵作用。在借鉴现有评价方法的基础上,通过对滤失介质的选择和改善,形成了渗透性滤失评价方法。该方法可操作性高,能反映出纳米颗粒的封堵效果,并通过对不同粒径的纳米颗粒封堵效果的评价对该方法进行了验证。该方法对于纳米颗粒的评价和在现场施工中的选择都有一定评价参考作用。
        Nanoparticle plugging agent is presently a research hotspot of drilling fluid technology, no special method has ever been developed for evaluating the plugging capacity of this category of drilling fluid additives though. When using the presently available methods to evaluate nanoparticles in laboratory, the evaluating results cannot be used to describe the plugging capacity of nanoparticle materials. Using the existing evaluation methods for reference, a new method has been developed to resolve this problem. In the new method, the filtration medium was carefully selected and modified, and the operability of the new method was improved. The evaluating results of the new method can reflect the plugging capacity of the nanoparticle tested, and nanoparticles of different particle sizes were tested using the new method to verify its applicability. The new method is of reference value to the evaluation of nanoparticles in laboratory and selection of nanoparticles in filed operations.
