The pore types of sandstone reservoir and evaluation of favorable reservoir of Taizhou Formation of Haian and Gaoyou depressions, which are the key regions in Subei Basin, were studied. The results showed that the sandbodies of delta, turbidite fan and fan-delta, which were composed of feldspatite debris sandstone and rock debris arkose with low maturity of content and texture, were developed, and there were many secondary pores and little primary pores in sandstone reservoir of Taizhou Formation of Haian and Gaoyou depressions; the first secondary pore zone located in the depth of 2 300~2 500 m in Taizhou Formation of Haian Depression, and the second secondary pore zone located in the depth of 2 600~3 200 m; it was different of pore evolution of reservoir in Taizhou Formation between Haian and Gaoyou depressions.
