摘要: 本文从生产实际和测试成果出发,根据冀中奥陶系潜山储集体的电性、物性特征和不同层段实行改造措施前后的产液特征,作了规律性分析,并对前人的储层划分标准提出修正,把旧标准的致密层、泥质层分别划出各自可改造的储层,将原划分的3类改划成5类;重新厘定了它们之间的划分标准。

关键词: 致密层, 泥质层, 酸化

Abstract: Based on the production and test results, the electrical and the physical characteristics of the Yizhong Ordovician buried-hill reservoirs,and the characteristics of the fluid一yields from different intervals before and after stimulation are analysed and regularized in this paper. A modification of the existing criterion of classifi-cation of the reservoirs is also suggested. Stimulable reservoirs are classified out from the compacted layers and the argillaceous layers respec-tively. In addition, instead of three types of reservoirs divided with the existing criterion,a five--type reservoir classifi一cation with a new criterion is proposod.

Key words: compacted layers, argillaceous layers, acidification
