摘要
一、问题的提出在石油、采矿、环境、能源和岩溶水文地质研究中,经常遇到基岩断裂带、岩体接触带控制的廊道式含水带和含水层非均质性相差十分明显(如降落漏斗长、短轴之比为5～20倍或更大)的脉状体地区内冷水或热水水量如何评价的问题。由于用径向流公式常不适应,与实际情况差距较远,所以实践中评价脉状或似脉状含水系统的水量觉得十分棘手。
On the basis of some problems about the evaluation of water capacity in the vein-like water-bearing body reported in the research of petroleum, environment,energy resources and karst hydrogeology,the authors made a pre- liminary study on the condition and method for evaluating the water capacity and parameter by linear flow theory through thoroughly researching the medium,flow domain and flow regime.According to the data about water level recovery and pumping of a group of wells in water-bearing zone of Langdao type limestone in the Fengcun iron deposit,the authors confirmed that linear flow existed in this area.Meanwhile,the hydrogeological parameters(T and μ)have been obtained through calculation of linear flow formulas,providing a practical way for evaluation of water capacity in the vein-like water-bearing system and for calculation of the parameters.
