宋芳屯油田扶杨油层储集岩主要为混合砂岩,泥质含量高、钙质胶结物含量较高。对储层的成岩序列进行了研究,储层大部分进入早成岩阶段B期和晚成岩阶段A期;主要的成岩事件有压实作用、胶结作用、溶蚀作用、交代作用等;压实作用是使孔隙降低的主要原因,钙质胶结物存在使孔隙空间进一步降低,骨架颗粒的溶蚀作用增加孔隙空间;扶杨油层储层敏感性主要有水敏、速敏和酸敏。
宋芳屯油田扶楊油層儲集巖主要為混閤砂巖,泥質含量高、鈣質膠結物含量較高。對儲層的成巖序列進行瞭研究,儲層大部分進入早成巖階段B期和晚成巖階段A期;主要的成巖事件有壓實作用、膠結作用、溶蝕作用、交代作用等;壓實作用是使孔隙降低的主要原因,鈣質膠結物存在使孔隙空間進一步降低,骨架顆粒的溶蝕作用增加孔隙空間;扶楊油層儲層敏感性主要有水敏、速敏和痠敏。

The reservoir rocks of Fu -yang in Songfangtun oil field is hybrid sandstone with shale high content, upper cement contant. The article researched the diagenesis sequence ,the reservoirs mainly came into early diagenesis stage and later diagenesis stage,diagenesis case has compaction, cementation, denudation, metasomasis. The reason which made the porosity decline is compaction,The calcitic cementation made pore space further declining, The denudation of skeleton grain increase the pore space ,The sensitivity of Fuyang reservoirs mainly hare properties of water sensitive, water sensitive, velocity sensitive and acid sensitive as well
