摘要
剖析了目前业内广泛应用的地质储量变化增量劈分方法的不足,即简单地将各储量参数变量引起的储量增量平均化,不能客观反映各储量参数的变化对储量变化值的影响。在储量参数与储量无量纲化基础之上,提出了考虑各储量参数增量对储量增量的差异化影响的观点,推导出了新的地质储量增量近似劈分公式,分析对比了不同劈分方法的应用效果,并简要探讨了储量参数敏感性分析及储量不确定性分析的思路。本文提出的方法可以应用于其他类似的基于参数增量的增量劈分,具有较广泛的实际应用价值。
A n analysis has been conducted on the pros and cons of the presently prevailing m ethod to breakdow n the O O IP increm ents( or changes) due to the variation of the O O IP-estim ate param eters.The O O IP increm ents are estim ated sim ply,and the contributions of all increm ents of relevant O O IP-estim ate param eters are taken equally in the m ethod,w hich is,show n in this study,not reasonable.The different im pacts of the O O IP-estim ate param eters on the O O IP increm ents should be fully regarded. So,a new approach is proposed w ith regard to this issue in w hich the nondim ensionalization of the O O IP-estim ate equation as w ell as all param eters is a prerequisite. C om parisons betw een these tw o approaches are conducted. The proposed approxim ate m ethod is m uch m ore acceptable com pared w ith the prevailing. The principle for the sensitivity and uncertainty studies is briefly discussed. The breakdow n m ethod for O O IP increm ents proposed in this study is m uch m ore practical and can be referenced in sim ilar studies.
