Based on the study of sedimentary facies��diagenesis of the clastic reservoir and the lithologic fea- tures as well the reservoir physical properties and controlling factors of Denglouku Formation--the 1st member of Quantou Formation in Wangfu area were investigated by means of integrate laboratory analysis techniques�� The re- sults show that the rock types of the reservoir in this area are mainly feldspar sandstone and lithic arkose��the pores of reservoir sands mainly are intragranular dissolution and intergranular in type�� But the pore structure is mainly of the type ��and the reservoir belongs to ultra �� low porosity and ultra �� low permeability reservoirs�� Favorable sed- imentary facies belt is the intrinsic factor to control the high value area distribution of reservoir property�� Cementa- tion is the key factors of attenuation of reservoir physical properties�� Compaction and cementation are important fac- tors of attenuation of reservoir physical properties in Denglouku Formation�� Dissolution formed part of 2 400 ��2 600 m secondary pore high value zone of the Denglouku Formation��
