| 摘 要： | 储层含油气性是评价储层的重要指标,而气测资料与储层含油气性具有较强的相关性。利用R型因子分析对大量气测参数优化组合降维分析,在气测参数大部分信息不丢失的情况下,提取少数几个因子得分意义下的气测解释综合参数,根据其方差贡献的相对大小确定权重。在试油证实的层位中,分别选取油层样品、油水同层样品、含油水层样品和干层样品对应的气测解释参数构造参考序列,把待识别样品对应的气测解释综合参数当作比较序列,进行加权灰色关联分析,得到已证实储层与待识别储层的关联度。建立适当的隶属函数,根据最大隶属度原则确定待判储层的含油气性。实例分析表明,该方法计算简单,正判率高,实用性强。 |

| Abstract: | Oil-gas potential is one of the important parameters for evaluating reservoirs.There is noticeable pertinence between gas logging data and oil-bearing reservoirs.Gas logging combined with parameters was extracted based on R-factor analysis,and the weights were ascertained based on the variance of gas logging combined with the parameters.Gas logging combined with parameters of tested reservoirs was considered as a reference series and unknown reservoirs were taken as comparison series.Correlation function of tested reservoirs and unknown reservoirs was established.Oil-gas potential of unknown reservoirs can be identified based on the light of maximum subject degree.The case suggests that the method is simple in calculation and the result is reliable. |
| Keywords: | gas logging information R-factor analysis grey correlation analysis Identification oil-gas potential |
