Reservoir Characterization of Special Dolomite Rock of Fengcheng Formation in Junggar Basin, China

Dolomites and eruptive rocks are well-developed in the Permian Fengcheng Formation Junggar Basin China, which oil gas accumulated extensively. Until now, high-yield industrial flows have been obtained dolomitic tuff of second unit Formation, demonstrates huge exploration potential thick layer massive tuff. The lithology this area has gradually transformed from dolomite, to siltstone east west. Moreover, well testing shows that reservoir is oil-saturated, production rate mainly depends on reservoir’s physical properties fracture development. In study, different types data including core data, log seismic used cooperatively characterize sedimentary, structure features then promising target zone study area. result indicates hydrocarbons most along deep fault Wu-Xia zone, will be favorable for next progressive exploration.
