摘要
以松辽盆地十屋油田下白垩统营城组特低渗透储层为研究对象,通过对大量岩石物理实验测量结果的综合分析,揭示该地区特低渗透储层的特征,建立了一套合理的孔、渗、饱储层参数模型,并通过对测井、试油、压汞等资料分析,确定了有效厚度下限标准,以满足油田特低渗透储层测井评价的需要,提高了该区目的层段油藏测井解释和有利区预测的精度。
This paper makes a research on extra-low permeability reservoirs in early Cretaceous Yingcheng formation of Shiwu oilfield in Songliao basin. By analyzing plenty of petrophysical measurements, extra-low permeability reservoir characteristics in this area has been revealed, and a model was built with reasonable reservoir parameters such as porosity, saturation and permeability etc. According to the analysis of logging, oil test and mercury injection data, the minimum effective thickness limit were determined to meet the requirements of the logging assessment of extra-low permeability reservoirs in oilfield, and the accuracy of logging interpretation in target reservoirs and the favorable zones prediction in this area has been enhanced.
