The Analysis of Volcanic Rock Reservoir Characteristics and The Main Control Factors——Take one well area of Xia Zijie oil-gas field in Junggar Basin as an example

With the development of the exploration degree,the volcanic rock oil gas pool already became the most important type of the oil-gas exploration in in northwesternmargin of Junggar Basin.To instruct the volcanic rock oil-gas exploration well,to start with the key element of the impacting accumulation of oil and gas—reservoir,taking one well area of Xia Zijie oil-gas field in Junggar Basin as an example,we have studied the volcanic rock characteristics of the reservoir,the reservoir type and reservoir properties.Our research believed that the volcanic rock reservoir type is diverse,the reservoir space type is too many,and the accumulation performance has very big difference and discontinuity,displaying greatly strengthened anisotropism.Above this foundation,we thoroughly analyzed the main control factors which influence volcanic rock reservoir.We thought that the lithic facies and the tectonic movement is the important attribute affecting the accumulation performance of the volcanic rock reservoir.
