一种新的地化参数交汇图版的建立与应用——以尼日尔Agadem地区的应用为例
|
摘要
应用常规的二维、三维地化交汇图版对油水分布关系复杂的储层进行解释分析时,受单一两参数或三参数之间含油性、含水性表征不明确的影响,很难准确地对油水层进行分析解释。以试油验证的地化数据为基础,从最直接反映储集层内油、气、水分布关系的地化热解参数入手,建立了由4个地化参数构建、3个二维子图版拼接组成的综合交汇图版,实现地化参数交汇图版内样品点含油性与含水性的综合对比分析,同时结合热解气相色谱分析技术、常规地质荧光分析技术对储层流体进行解释分析,得出最终解释结果。该图版解释方法在尼日尔Agadem地区应用后,取得了很好的效果。
It is difficult to accurately interpret reservoir fluid with complex oil-water relation, by the conventional two-dimensional or three-dimensional geochemical chart, because of the fuzzy oil-bearing or water-bearing representation reflected by single two or three geochemical parameters. On the basis of geochemical data validated by oil production test, the geochemical pyrolysis parameters that directly reflect the distribution relationship of oil, gas and water in the reservoir are constructed. Four geochemical parameters are constructed and three two-dimensional subgraphs are constructed, which realize the comprehensive and comparison analysis of oil-bearing and water-bearing characteristic of samples. The final reservoir interpretation is obtained through the analysis of comprehensive geochemical cross chart united pyrolysis gas chromatography and geological fluorescence. The application of geochemical cross chart has achieved good effects in Agadem block, Niger.
