Abstract

According to the analyses of the seismic sections and balanced sections,subsalt structural deformation strength in the east is higher than that in the west of Qiulitage structural belt of Kuqa foreland basin.Structural shortening rate in the east part ranges from 13% to 25% and subsalt structures mainly include fault-related folds,imbricated thrust and duplex in the east.Structural shortening rate is below 10% and structural styles are a series of fault blocks in the west,such as back thrust and step thrust.Using the principle of back stripping and basin modeling technology,the result suggests subsidence rate is higher in the east than that in the west.The differences in structural deformation and subsidence rate have influence on reservoir diagenesis and physical property.In the east,structural deformation is intensive.Subsidence rate is higher and deep burial time is longer.The compaction is strong and reservoir diagenesis stage is in middle diagenesis A2-B period.Visual compaction rate ranges from 37% to 64% and reservoir physical property is bad.Intense tectonism leads to development of the fractures which greatly improve reservoir permeability.On the contrary,structural deformation is faint and subsidence rate is lower in the west.Shallow burial time is longer.Visual compaction rate is between 24% and 55%,reflecting the compaction is weaker.Reservoir diagenesis stage is in middle diagenesis A1-A2 period.Reservoir physical property is better in the west.Tectonic-diagenesis is a crucial geological factor causing the inferior physical property of the reservoir in Qiulitage structural belt of Kuqa foreland basin.
