摘要
根据岩芯样品渗透率分析值和岩石水平应力，以回归分析技术研究了二者的定量关系。水平应力由测井资料计算，检查了不同应力模型的适用性。用常用对数分析水平应力与渗透率的关系符合实际资料，取得了较好的效果。引入自然伽马测井，减少了岩性的影响，提高了实用意义。增加分辨率高的测井方法处理，使确定的渗透率有较高的分辨率。
Quantitative relationship between measured permeability of rock core and horizontal stress is studied by regressive analytical technique. The horizontal stress is computed with logging data. The adaptability of various models on stress is checked. The logarithmic relationship between the permeability and horziontal stress is got with practical information and the result is good. The effect of lithology is decreased by the ray log, but the practical unility is increased. By the well log with good resolution, the permeability has higher resolution.
