油藏规模序列法的改进及应用

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。

Improvement and Application of Reservoir Size Sequential Method

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.
