Figure 9. Microscopic characteristics of fluid inclusions in the third interval of the Paleogene Shahejie (Es3) sandstone reservoirs of the Bonan oil field. (A) Oil inclusion in quartz (Q) healed fracture (plane-polarized light). (B) The same image zone as (A), showing oil inclusion in Q healed fracture with blue-white fluorescing under ultraviolet light. (C) Aqueous inclusion in the calclite II cement (Cal II) (plane-polarized light). (D) Aqueous inclusion in ankerite (Ank) cement (plane-polarized light). Cal II = second-phase calcite cement.
