火成岩双重介质油藏测井参数评价技术

Logging interpretation technique for double media reservoir of igneous rock

以岩心分析、测井资料为基础,结合岩电实验、压汞分析、CT成像、生产动态等资料,根据火成岩非均质性强,缝、洞发育,具有典型的双重介质储层的特点,运用体积模型和统计模型相结合的方法,针对不同岩性建立了一套适合于火成岩缝洞型复杂双重介质储层参数定量计算的模型。应用该模型对枣园火成岩储层基质和裂缝物性参数进行了计算。结果表明该模型对于储层评价、储量计算与地质建模具有重要意义。

A model has been established to quantitatively calculate parameters of igneous fracture-cavity double media reservoir based on core analysis, logging, core-electricity experiments, mercury intrusion analysis, CT imaging, and production performance data according to heterogeneous characteristic of such reservoir through combination of volume model and statistic model. The model has been used to calculate physical parameters of igneous reservoir matrix and fractures in Zaoyuan Oilfield, which are important for reservoir evaluation, reserve calculation and geological modeling.
