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。
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—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 respectively. In addition, instead of three types of reservoirs divided with the existing criterion, a five—type reservoir classifi —cation with a new criterion is proposed.
