Chunfeng Oilfield was located in the West Edge of Junggar Basin, with 17 exploratory wells drilled in pore- fracture type reservoirs of Volcanic Rock, among which 4 exploratory wells obtained industrial oil flow. To expand exploration results, high yield mechanism research is developed. Research shows that, the advantages for high yield conditions of Volcanic Rock in Chunfeng Oilfield are: volcanic tuff reservoir, core oil grade with oil spot, reservoir fractures and lower underground oil viscosity. In this process, pore-fracture seepage additive effect has been discovered. Pore-fracture produced better development effect than both simple pore and fracture. Pore-fracture additive permeability is many times the log interpretation permeability, and it provides theoretical basis for horizontal well and long channel fracturing.
