测井资料在气藏储量计算中的应用

The application of well log data in gas reserves estimate

在储量计算中,优良的测井资料占有非常重要的地位,尤其对非常规的复杂岩性气藏,大量的储层评价参数都要通过测井分析处理而取得,有些数据是岩芯分析无法得到的。在一定范围内,测井资料是进行地层对比的最可靠的资料。测井资料的标准化是气藏描述,储层横向预测、追踪的前提。储层评价参数的精度取决于处理参数的选取是否合理。文章介绍了储量计算中测井资料应用的全过程,证实应用此方法可以直接完成复杂岩性气藏的储量计算。

It is well known that good well log data play an important part in reserves estimate,particular in non-normal complex litho logic gas reservoir, In these cases,a great deal of reservoir evaluation parameters are detcrmincd by log data proccssing and analysis,and some of them can not bc gattcn by core test, In certain extent,log data is the most rcliable data for stratigraphic corrclation. The normalization of log data is the premise both for gas reservoir deseription and lateral prediction.The accuracy of parameters from log data aro dopended on the selection of processing parameters.In this paper,wc introduce the whole process about log data application in reserves cstimate,and demenstrate such process are suitable for complex lithologic gas reservoir,
