沥青对储层物性及油层产能的影响

沥青充填在储层中使储层的孔隙度和渗透率降低，非均质性增强。以准噶尔盆地三台—北三台地区为例，对沥青含量不同的储层进行有机溶剂浸泡，浸泡前后进行物性实验对比，分析了沥青对储层物性的影响，指出了沥青可大大降低储层的孔隙度和渗透率，尤其是对细砂岩和填隙物多的砂岩影响更大，指出沥青是引起该区油层低产的重要原因之一，对提高含沥青储层油气的产能具有参考意义。

A Study on Financial Support for Energy-saving and New Energy Industry

The bitumen filling in reservoir makes porosity and permeability decrease and more inhomogeneous.Santai-northern Santai of Junggar Basin is taken as example，the reservoir samples with different bitumen content are soaked with organic solvent，the physical property contrast before and after soaking is conducted，the influence of bitumen on the physical property is analyzed.It is recognized that bitumen will greatly decrease reservoir porosity and permeability，especially fine sandstone reservoir and the sandstone reservoir with a lot of fillings.It is pointed out that the bitumen is one of the factors which makes reservoirs low productivity.The research on the reservoirs with bitumen is valuable for enhancing oil productivity.
