Based on the petrologic data of over 40 wells， the characteristics and main controlling factors of the Permian reservoirs in Wuxia area were systematically described. The Permian reservoir in this area is diverse， which mainly includes terrestrial clastic rocks， dolomite or dolomitic rocks， volcanic clastic rocks and volcanic rocks. The reservoir pore space is dominated by secondary pore， and the pore spaces of the clastic reservoir are mainly intergranular solution pore， dissolved pore of interstitial materials，and microfracture. The dolomite reservoir is dominated by fractures; volcanic clastic rock and volcanic reservoirs are dominated by gasreleasing pore. The reservoir  is characterized by  lowmedium porosity and permeability. Its pore texture types include small pore and fine throat， micro pore and tiny throat， and micro pore and mini throat. The reservoir is classified as poor to moderate categories of reservoirs and possess the lowmoderate porosity and permeability. The comprehensive evaluation showed that lithology and grain size， diagenesis and compaction， dissolution and fracturing are the main controlling factors of reservoir quality in this area. Of them， lithology and grain size are the main influencing factors for reservoir property， mechanical compaction is the main controlling factor of porosity reduction which may have caused 2365 percentage points of porosity loss. Dissolution， fracturing and faulting improved the reservoir property effectively. Comprehensively considering the reservoir property and the controlling factors， the reservoirs are divided into five categories， of which， type Ⅲ， Ⅳ， Ⅴare the main types in Wuxia area.
