为了消除目前储量参数碾平算法中的系统误差和降低进位误差,对原有的储量参数碾平算法进行了改进。采用地面脱气原油体积、质量、溶解气约束方法碾平储量合计单元各项参数,从而有效消除储量参数碾平中的单项系统误差;将各碾平参数值在各自变化范围内按照最小单位步长先离散化,再采用全排列组合法优选出使体积、质量、溶解气储量相对误差平方和达到最小的一组参数,该组参数即为合计项的最优储量参数碾平项选择。经过检验,利用该方法能够降低进位误差。
In order to eliminate the system error and the carry-in error in the current storage parameter flattening algorithm, the original storage parameter flattening algorithm is improved. Using the method of volume, quality and dissolved gas constraint of ground degassing crude oil to grind out the parameters of the total unit of reserves, the single systematic errors in the grinding parameters of the reserves are effectively eliminated; and the values of the grinding parameters are adjusted within the respective minimum range according to the minimum unit step The first discretization, and then use the full permutation and combination of law to optimize the volume, mass, dissolved gas reserves relative error sum of squares to minimize a group of parameters, the group of parameters is the sum of the optimal reserve parameters grind item selection. After testing, using this method can reduce carry error.
