摘要: 苏德尔特油田南屯组Ⅰ—Ⅳ油组为火山碎屑岩储集层,主要岩性有凝灰质砾岩、凝灰质砂砾岩、凝灰质砂岩、凝灰质泥岩。压实作用、胶结作用、脱玻化作用、矿物解理缝和矿物炸痕等是主要成岩作用。总的来说,储集层物性较差,Ⅰ—Ⅲ油组孔隙度、渗透率值相对较大,Ⅳ油组孔隙度、渗透率值要比Ⅰ—Ⅲ油组小得多。粒径对储集层物性起决定性作用,颗粒越大储集层物性越好,压实、胶结作用是使储集层变差的主要因素,脱玻化作用、矿物解理缝和矿物表面炸痕等对储集层物性产生有利影响。

Abstract: In Sudeerte oilfield, I-IV oil measures of Nantun formation belong to a volcanoclastic reservoir with lithologies of tuffaceous conglomerate, tuffaceous glutenite, tuffaceous sandstone and tuffaceous mudstone. Compaction, cementation, devitrication, mineral cleavage crack and blast trace are its main diageneses. The reservoir physical properties are poor on the whole, but I-III oil measures are relatively bigger and IV oil measure is much smaller than I-III in porosity and permeability. The particle size has decided effect on the reservoir properties, namely, the bigger the particle size is the better the reservoir properties are. Compaction and cementation are the main factors to make the reservoir properties poorer, while devitrication and mineral cleavage crack and blast trace have some favorable effects on them.

Key words: Sudeerte oilfield, volcanoclastic rock, Nantun formation, reservoir character, diagenesis
