Based on the analysis of rock slides, casting slides, scan electron microscope and X\|ray diffraction etc, the characteristics of diagenetic evolution of clastic sandstone in Quan 4 Formation at Longxi region, Songliao basin are studied. The diagenesis in Quan 4 Formation is in the mesogenetic stage, and is subdivided as A1 and A2 stages. Four types of diagenesis are recognized, including compaction, cementation, dissolution and metasomatism. The compaction and cementation destroy the primary pore structure intensively, and dissolution betters the pore structure effectively. Secondary porosity zones are developed in 1600~2000 meters.
Key words： Diagenesis; Reservoir property; Quan 4 Formation; Longxi region.
