摘要
This paper mainly use the Hong-143 and Hong-146 well that rich in dawsonite-bearing sandstones as research objects. According to the analysis of conventional thin sections, alizarin red-staining, SEM, INCA energy spectromete, micro-thermometry, the diagenetic paragenesis succession of dawsonite-bearing sandstones, in particular, the homogenization temperature of fluid inclusion have been studied in detail. The diagenetic paragenesis of the Honggang Oilfield is clay minerals→secondary quartz overgrowths→calcite→ dawsonite→ankerite→quartz healing microfracture. On the basis of intensive micro-thermometry, the peak of the homogenization temperature is 110～120 ℃ in the calcite; while 130～140 ℃ in the quartz healing microfracture. The formation temperature of dawsonite is between calcite and quartz healing microfracture, which is 120～130 ℃.
