摘　　要：油气储集层是测井解释与评价中的主要研究对象。随着石油工业的发展 ,油气储集层的研究显得越来越重要 ,它不但决定油气储量的大小 ,而且直接控制油气井的产能及最终采收率。低阻油气层的特征不同一般储层 ,因为它有不同的地质特征 ,其中与测井密切相关的因素主要包括 :储集层岩性特征 ;储集层物性特征 ;储集层电性特征 ;储集层流体的性质及其分布特征等。它们是进行低阻油气层测井精细解释与评价的地质基础 ,这些地质因素对各种测井响应的影响程度 。Reservoir is the principal object of log interpretation and evaluation. With the development of petroleum industry, the reservoir study is getting more important, because the reservoir controls not only the oil and gas reserve but the productivity and recovery as well. The characteristics of the low-resistivity reservoirs are different from those of the common shaly sandstone reservoirs for their different geological characteristics. Among which related to the log information are chiefly lithology characteristics; Physical property; electrical characteristics, fluid characteristics and so forth. They are the geological basis of fine log interpretation and evaluation, and the degree of influence of these factors on well log response is the physical basis of log evaluation.
