摘要
Based on the analysis of diagenesis and formation sequence of the authigenic diagenetic minerals of Yanchang 4+5 sandstone reservoir in Jiyuan area in Ordos Basin, the characteristic of fluid inclusions in diagenetic minerals and the representing hydrocarbon accumulation phases are studied. The results show that the main diageneses include compaction, pressolution, cementation, recrystallization, dissolution and fissuring process. The diagenetic minerals are authigenetic quartz, albites, dolomite, calcite and clay mineral, etc.
