油藏自适应历史拟合的研究

Research of Adaptive History Matching in the Petroleum Reservoirs

利用优选与正交设计等理论,给出了单因素和多因素油藏自适应历史拟合的序贯试验法.由可调参量的变化范围以及拟合对象的最大可能值,选出最优值,在此基础上进行试验,避免了过去人工历史拟合的不足,可以提高预测的可靠性,有利于油田的合理开发.最后,编制了计算机程序对实例进行计算,计算结果表明该方法行之有效.

This paper applies the theories of optimization and orthogonal design to give the sequential search method of singlefactor and multifactor for adaptive history matching in the petroleum reservoirs.According to the range of changeable parameters and the maximum of the matched object,an optimization value is chosen by this paper's theory.Then the research is carried out.These methods can avoid the shortage of artificial history matching and improve the reliability of forecast and are favorable to rational development of oil field.At last an example is calculated through lots of computer program.From the result we can see that these methods are effective. 
