Abstract

Abstract:

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.

Key words: reservoir bitumen, reservoir physical property, Junggar Basin, soak test, oil reservoir low productivity, hydrocarbon productivity
