摘　　要：通过对虚拟的可地浸砂岩型铀矿设定理想化的参数和条件,建立净现值模型。针对5点型和7点型两种井型进行定量计算和单因素分析,认为井距在15~40m范围内比较合理。对于井场长度、宽度大的矿床,5点型井网较7点型井网具有明显的经济优势,反之则反。对于深层矿床,适合更宽的井距,井距35m左右最优;浅层矿床,更适合紧密的井距,较小的井距(15m)的井网更有利。By setting ideal parameters and conditions for the virtual in-situ leachable sandstone type uranium deposit,the net present value model is established.Based on quantitative calculation and single factor analysis of 5-point and 7-point well types,it is considered that the well spacing is reasonable in the range of 15-40m.For deposits with large well site length and width,5-point well pattern has obvious economic advantages over 7-point well pattern,and vice versa.For deep deposits,it is suitable for wider well spacing,and the optimal well spacing is about 35m;for shallow deposits,it is more suitable for tight well spacing,and the well pattern with smaller well spacing of 15m is more favorable.
