火成岩油气藏储量计算有关问题探讨
|
摘要
针对火成岩油气藏具有岩性和岩相复杂、储层非均性强的特点,通过分析不同岩相、不同储集类型的岩石物理特点、测井响应特征和油水系统,提出适合火成岩储层的储量计算单元划分观点。以岩心分析为基础,充分利用成像与核磁测井识别有效厚度。采用细分储集类型,并将常规测井、核磁测井、压汞曲线相结合,建立孔隙度、饱和度参数解释模型。采用地震测井约束反演技术,定量描述储量单元参数。以上多种方法和综合技术的应用,可较好地解决缝洞型双重介质火成岩储量参数解释困难、储量计算精度低的难题,并对类似火成岩油气藏的储量计算评价具有一定指导意义。
Igneous reservoirs feature in complexities of lithologies and lithofacies and strong heterogeneity.This paper analyzed the petrophysical characters,log responses,and oil-water system of reservoirs with different lithofacies and reservoir types,and proposed a unit division method suitable for reserve calculation of igneous reservoirs.Effective reservoir thickness is recognized through analyzing core,FMI and NMR log data.Models for porosity and saturation interpretation are established through subdivision of reservoir types and integration of conventional log,NMR,and intrusive mercury curve.Parameters of the reserve calculation units are described quantitatively through log-constrained seismic inversion.A comprehensive application of the above-mentioned methods and technologies would solve successfully such issues as difficulties in interpreting reserve parameters of fractured-vuggy igneous reservoirs with dual media and the inaccuracy of reserve calculation.Furthermore,it may help the evaluation of reserve calculation of similar igneous reservoirs.
