| 摘 要： | 利用传统的渗透率计算方法无法准确计算火成岩储层的渗透率.在对松辽盆地北部徐家围子断陷和南部长岭断陷中部凸起带火成岩储层岩心和测井资料研究的基础上,认为研究区火成岩储层不同类型的孔隙对储层渗流能力的贡献不同,遵循不同的渗流规律.提出利用孔隙分类法把储层孔隙分为微孔、中孔和大孔而进行储层渗透率计算的方法.根据孔隙所含大孔、中孔和微孔的比例可以把储层孔隙分成8个级别,储层的渗流能力和存储能力随孔隙级别不同而不同.利用核磁共振T2分布谱划分与孔喉半径相关的孔隙类别.岩心和测试资料表明该方法计算结果准确可靠.

| Abstract: | The permeability of igneous reservoirs can not be calculated accurately by traditional permeability estimating methods.The research of igneous reservoir core and logging data of Xujiaweizi fault and Changling fault in Songliao basin,China,has proved that different types of pores contribute differently in percolation velocity of igneous reservoirs,and different pore types follow different seepage rule.Put forward is a new igneous reservoir permeability calculation method to distinguish the pores into micro-p... |
