摘要
油藏规模序列法是油气资源评价中一种重要的方法,但是目前标准算法以最小标准差为原则选择k值的做法容易导致不合理的预测结果。提出了一种改进算法,首次提出k线图的概念和确定k值的"1-2-2法则"。大量测试结果表明",1-2-2法则"结合k线图所确定的k值更加合理,对于提高预测准确度有很大的帮助。
The reservoir size sequential method is an important method for petroleum resource estimation. However, with this method irrational predicted results are often gained by selecting value k in terms of minimum standard error as principle. This paper proposes an improved algorithm in terms of k-line chart concept and ＂1-2-2 principle＂ for determine value k. The numerous testing results indicate that ＂1-2-2 principle＂ combined with k-line chart will be more reasonable to give value k, and more helpful to improve the predicted precision.
