摘　　要：提出了一套针对气层损害的室内评价推荐标准 ,内容主要包括低渗气层敏感性评价实验程序和钻井液污染岩样评价实验程序 ,利用国内五个不同油田的低渗气层岩心 ,采用新标准进行了有关评价 ,初步证明了新标准的可行性和有效性。A set of new evaluating standards for the damage to low-permeability gas sands, which includes the experimental procedure for the sensibility evaluation and that of polluting core samples with mud, is developed. Core samples of low-permeability gas sands coming from five different oil fields are evaluated with the new standard and the results show that the standards are feasible and effective.
