苏里格东区召51-统41井区气藏为典型的岩性气藏,主要勘探层位是盒8段、山1段。通过对岩心、铸体薄片、扫描电镜及物性资料的分析,对该区储层岩石学特征、孔隙类型、储层物性及其影响因素进行了研究。结果表明:该区储层岩石类型主要为岩屑砂岩、岩屑石英砂岩;储层为孔隙型储层,孔隙以残余粒间孔、溶蚀孔、晶间孔为主;孔隙结构具有中-小孔喉、分选中等、排驱压力高和主贡献喉道小的特点;同时储层具有低孔、低渗的特点。沉积环境和成岩作用是影响储层物性的主要因素。
囌裏格東區召51-統41井區氣藏為典型的巖性氣藏,主要勘探層位是盒8段、山1段。通過對巖心、鑄體薄片、掃描電鏡及物性資料的分析,對該區儲層巖石學特徵、孔隙類型、儲層物性及其影響因素進行瞭研究。結果錶明:該區儲層巖石類型主要為巖屑砂巖、巖屑石英砂巖;儲層為孔隙型儲層,孔隙以殘餘粒間孔、溶蝕孔、晶間孔為主;孔隙結構具有中-小孔喉、分選中等、排驅壓力高和主貢獻喉道小的特點;同時儲層具有低孔、低滲的特點。沉積環境和成巖作用是影響儲層物性的主要因素。

The Zhao 51 -Tong 41 well block, east Sulige gasfield is a typical lithologic gas reservoir, He-8 Member and Shan-1 Member are the main exploration objects. Study of various data such as core, cast thin section, SEM and physical properties indicates that the block consists dominantly of lithic sandstone and lithic quartz sandstone with intergranular pore, intragranular pore and dissolution pore and pore structures characterized by medium to small throat, moderate sorting, high displacement pressure and small major throat. The reservoirs are characterized by low porosity and low permeability. Sedimentary environment and diagenesis is the main controlling factors of reservoir physical properties.
