Abstract

Abstract

By core physical property, casting slice, scanning electron microscope analysis with energy disperse spectroscopy, the densification process of Chang 6 sandstones in western Ordos Basin was studied quantitatively. The study showed that the initial porosity and permeability of sandstones in the area were 39.3% and 22400×10^-3 μm² respectively, and its densification process was divided into two stages. In the course of early diagenesis stage, both calcite and chlorite coat cements and mechanical compaction caused the sandstones into ultra-low permeability reservoir whose porosity and permeability were 8.0% and 0.17×10^-3 μm² apart. During hydrocarbon accumulation in middle diagenesis stage A, hydrocarbon with organic acid came into this ultra-low permeability sandstones, and under organic acid circumstance feldspar dissolution formed secondary pore, which made porosity and permeability up to 11.6% and 0.61×10^-3 μm² individually. So the relationship between the densification process of Chang 6 sandstone and hydrocarbon accumulation is first densification then accumulation and accumulation with increased porosity and permeability.
- first densification then accumulation,
- accumulation with increased porosity and permeability,
- ultra-low permeability sandstone,
- Chang 6,
- Ordos Basin
