Abstract: By the detailed descriptions of the seven cross sections from Kuche River, Kelasou River and the rock cores from Kela Nos.1,2 and 3 wells,couple with. The data SEM analyses,the reservoir characteristics of Bashijiqike Formation can be concluded as follows: (1)the compositional and textural maturations of the rocks are relatively lower; (2)the reservair pore types include intragraindissolved pores, matrix dissolved pores, cement dissolved pores and primary intragranual pores; (3) the pore txture is finepore, middle throat ;(4) the reservoir types are primarily the low porelow permeability typeⅡ, secondarily the low pore─middle permeability type Ⅲ.
