Demonstration Of Volcanic Rock Reservoir Based On Xushen 9-1 Well In Xujiaweizi Substation Layer Features And Evaluation

The depth of the Songbei area is rich in natural gas resources,of which the main exploration area is the Xujiaweizi fault depression.The Yingcheng Formation above the source rocks of the Shahezi Formation in the central fault zone has concentrated most of the natural gas reservoirs.Recently,the exploration situation of natural gas is not optimistic.Because of the continuous increase in exploration efforts,we have gradually discovered deep-seated volcanic rocks,conglomerates and other highly complex reservoirs.In the face of such reservoirs,the conventional reservoir prediction technology is obviously overwhelming and unable to perform exploration and development tasks.Based on the above considerations,it is necessary to thoroughly study the differences in the conditions of natural gas reservoirs and their main control factors.Only in this way can stable production and efficiency be improved during the development of natural gas reservoirs.Xushen 9-1 well is a development evaluation well located at the Changjing section of volcanic rocks in the first section of the first section of the Xujiaweizi area.This study mainly recognized the well from the aspects of volcanic lithology,volcanic facies,pore structure,diagenesis and reservoir evaluation,and finally conducted reservoir evaluation.The fine study of Xushen 9-1 well is of great significance to the understanding of the volcanic rocks in the Yingcheng section of the Xingcheng area.Knowledge of the geological changes between the craters can lay a foundation for the design of the gas field development plan and the future development of natural gas.
