摘要
利用不确定分析法快速评估圈闭资源量是勘探类新项目及油气田开发前期评价的有效手段,较常规确定性算法更为客观,认识更为全面;较建模法,对大量的原始性数据依赖性相对较小,更易实现。从基本计算公式入手,着重分析了资源量计算主要参数的地质影响因素,就重要计算参数的概率分布模型如何选择及赋值、有效性检验方法进行重点研究,总结了参数相关性分析及软件实现抽样模拟原理等评估节点。在此基础上,以俄罗斯海上某区块内圈闭单层为例,快速确定其资源量高中低范围,为项目的潜力评估提供参考。
It is quite effective to evaluate the trap resources of new exploration projects by using probabilistic method. Compared with deterministic algorithm,probabilistic method is more objective and comprehensive,and compared with modeling method,it is relatively less dependent on a large number of original data and is easier to implement. Starting with basic calculation formula,the geological factors influencing the main parameters for calculating the trap resource were analyzed,and the probability distribution models of the parameters were studied,such as the selection and parameter assignment ways of the models,the determination of main parameters for trap resource calculation,validity test methods,etc. The correlation between the main parameters for trap resource calculation was analyzed.Finally,taking a trap of an offshore block in Russia as an example,demonstrate how to quickly calculate the high,medium and low resource ranges of the trap using probabilistic method.
