Diagenesis of Chang 6 Reservoir in Well W102 Area,Ordos Basin
The reservoir characteristics and diageness of Chang 6 reservoir in well W102 area in Laoshan area of Ordos Basin were studied based on casting thin section and scanning electron microscope.The research results show that the rock type of Chang 6 reservoir in well W102 is mainly gray fine-grained arkose,and the reservoir is a typi-cal low porosity-ultra low porosity,ultra low permeability-ultra low permeability reservoir.In addition,compaction during diagenesis is destructive diagenesis and has no dominant influence on reservoir physical properties;The cementation is complex and has great influence on porosity;The dissolution is constructive diagenesis,and the increase of dissolution rate has a positive effect on the improvement of reservoir porosity and permeability.
