| 针对现有的资源总量随机求和中存在的资源总量曲线形态有时呈偏态分布的问题，提出了对其随机抽样方法 的改进方案,即把随机抽样入口由原来定义在(0,1)区间上改为定义在(0,^)区间上为第；个局部地质单元的 石油资源量保险系数),利用(0,A)区间上均匀分布的随机数对风险分析后的资源总量分布函数进行随机抽样。改 进后的方法克服了传统抽样方法的不足,实现了均匀分布随机抽样,使资源总量趋于正态分布。 |

| Abstract: |
| In the existing methods of random summing of total resource, the shape of the total resource curve sometimes distributes skewly，in view of which，the new method was put forward to improve random sampling. TTie entrance of the random sampling was not defined in the interval of (0，1)，but in the interval of (0,k)，where is the insurance index of the petroleum resource of the 2th local geological location. The random numbers distributing in the interval (0,A:t ) were used to make a random sampling to the resource distribution function throu^i the risk analysis. The improved method overcomes the flaw of the traditional sampling method, realizes the even distribution random sanpling and makes the total resource tend to normal distribution. |
