摘　　要：储层损害室内评价是一个统计性实验,必须经过大量的实验,才能对现场情况作出全面、准确的判断;同时它又是一个模拟性实验,其实验方法、实验条件和判别规则对最终的实验结论都会产生决定性影响。目前储层保护室内评价结果的稳定性和重复性不太好,降低了对现场作业的参考性。因此,对室内评价过程中实验岩心的选择、建立束缚水的判断进行了规范,对实验条件进行了确定,从而消除了歧义和误差,提高了评价结果的稳定性、为石油的开采提供保障。The lab evaluation of reservoir damage has the characteristics of statistics and simulation,so abundant of experiments should be needed,also the test methods conditions and regulations should be restricted to get comprehensive and precise conclusions.In this paper,the chosen of cores and the judgement of bound water were restricted,and the experimental conditions were confirmed,so the errors can be minimized and the stability of evaluation can be improved as well.
