| 中文摘要: |
| 当前盐湖卤水液体矿产资源量估算方法参照固体矿产执行，最常用的方法是地质块段法。液体矿产的特点一是存在流动性，二是赋存于地层孔隙中。孔隙的体积即为液体矿产的体积，这一点明显区别于固体矿产。采用地质块段法估算盐湖卤水液体矿产资源量往往会产生一定的误差，在储量估算时往往面临不同地勘单位估算得到的资源量结果相差较大的情况。本文提出采用三步法估算液体矿产资源量，在传统地质块段法的基础上，有效规避参数求均值带来的估算误差，最大程度接近实际资源量。首先按矿体沉积特征(厚度)划分块段，其次按品位分区划分块段，再次按孔隙分布划分块段，最后对 3种计算结果求均值。综上发现，采用不同方法，资源量估算结果不相同，误差较大，而采用本文的方法，可以有效消减各类因素的影响误差，有效提高资源量估算精度。 |

| At present，the estimation of liquid mineral resources refer to solid mineral resources，the most commonly used method is geological block method. The characteristics of liquid minerals are of fluidity and occur.rence in the formation pores. The volume of pores is the volume of liquid minerals，which is obviously different from solid minerals. In this paper，a three-step method is proposed to estimate the amount of liquid mineralresources. On the basis of the traditional geological block method，the estimation error caused by the mean value of parameters can be avoided effectively，and is close to the actual amount of mineral resources at the maximum. First，blocks are divided according to the sedimentary characteristics(thickness)of ore body. Secondly，blocks are divided according to the grade，Thirdly，dividing the blocks according to the pore distribution. Finallycalculate the mean value of the three kinds of calculation results. It is found that the estimation results of resource amount are different with different methods，and the error is large. By using this method，the error of various fac. tors can be reduced effectively，and the precision of resource estimation can be improved effectively. |
