摘要
针对阿尔凹陷储层评价,应用核磁共振测井资料开展储层喉道大小与孔隙结构特征关系、喉道大小与渗透率关系研究,提出了基于核磁共振测井孔喉的渗透率计算方法,提高了渗透率计算精度。在此基础上,建立储层分类标准及低孔隙度低渗透率储层有效性评价方法,在实际应用中见到了良好的效果,在阿尔凹陷高效勘探开发工作起到了积极的作用。
According to Artala sag log evaluation,application of NMR logging data,the relationship between reservoir throat size and pore structure characteristics and permeability,calculation method of pore-throat permeability is proposed based on NMR data,which greatly improves the permeability accuracy.On this basis reservoir classification standards and the effectiveness evaluation method of low porosity and low permeability reservoir are established.Good results are achieved in actual application.It has played a positive role in the efficient exploration and development of Artala sag.
