In the comprehensive evaluation of low-permeability reservoirs, we add a new parameter, the brittleness index. Thus, a comprehensive evaluation method for the low-permeability & difficult recovery reservoir is proposed. It is indicated that the difficult recovery reservoir is typically a low porosity and ultra-low permeability reservoir. The differences of the physical properties and the pore-throat characteristic parameters of the reservoir in different blocks are due to the differences of the micro-pore structures of the reservoir. Meanwhile, the exploitation potential of the difficult recovery reservoir of Qaidam Basin is analyzed and evaluated. The classification results are consistent with the actual development and production of the oilfield., authors=TIAN Xiao¹, YANG Zhengming², CHU Shasha², ZHAO Guomei³, WEI Chengzhang³, authorsList=TIAN Xiao, YANG Zhengming, CHU Shasha, ZHAO Guomei, WEI Chengzhang, authorCompany=1.
