CURRENT RESEARCH SITUATION AND THE PROBLEMS OF VOLCANIC ROCK RESERVOIRS

In recent years,as the breaking through progress of the exploration and exploitation for volcanic rock reservoirs,the reservoirs have become new targets for exploration and exploitation.On the basis of studying the existing literatures on the reservoirs home and abroad,the particularity of the volcanic rock reservoirs,the types and the genesis of reservoir space,the evolution feature of the space and the types of reservoirs are summered.Volcanic rock reservoirs are not in some lithologies,there is huge difference between it and sedimentary rock reservoirs.The reservoir space of volcanic rock reservoirs can be grouped in to four types according to the genesis,i.e.,primary pore,second pore,primary fracture and secondary fracture,its formation and evolution underwent five stages,i.e.,primary formation stage,weathering leaching stage,shallow bury digenesis stage,tectonic faulting stage and deep bury dissolution stage.At last,it is pointed out that there still are some problems in volcanic rock reservoir research,and research approach in the future is presented aiming at the problems.
