  • The cementation and its relationship with tectonic fractures of sandstone of Bashijiqike Formation of Cretaceous in DB gas field of Kuqa Sub-basin were researched through thin-section analysis, core observation, cathodoluminescence analysis, scan electricity microscope observation, X-ray diffraction, fluid inclusion and reservoir physical parameters analysis, etc and combining histories of tectonic development.

Abstract: The cementation and its relationship with tectonic fractures of sandstone of Bashijiqike Formation of Cretaceous in DB gas field of Kuqa Sub-basin were researched through thin-section analysis, core observation, cathodoluminescence analysis, scan electricity microscope observation, X-ray diffraction, fluid inclusion and reservoir physical parameters analysis, etc and combining histories of tectonic development. It is recognized that the sandstone of Cretaceous in DB gas field is fracture-pore reservoir and with ultra-low porosity and ultra-low permeability. The developed fractures are the main factor of high production capacity. The sandstone has strong diagenesis and the main cements are authigenic carbonate minerals. The cementation and transformation of clay minerals have strong causal relationship. There are three cementation stages, which are “before 6 Ma”, “6~5 Ma” and “3~2 Ma”, respectively. Multi stage cementations are closely related to the validity of three stages tectonic factures in DB gas field. Only the third stage fracture (formed at the end of N2) is the most effective reservoir space for missing completely main cementation.
