Development model and logging division method of volcanic weathering crust reservoir
In recent years,important discoveries have been made in the exploration of the weathered crust reservoirs on the top of the volcanic rocks in Junggar Basin.However,the structural characteristics of the weathered crust reservoirs are not clearly understood,and there is no effective logging division method.This paper takes the Carboniferous of Zhongguai uplift in Junggar Basin as an example,systematically analyzes the structure,logging response mechanism and development models of the volcanic weathering crust by geological and logging data,establishment of weathering crust index model based on response characteristics of logging curves,and established a logging evaluation method for the volcanic weathering crust reservoir structure.It provides a reference for finding the dominant reservoir of weathered crust and oil testing perforation in the later stage,which has good application effect.It has important guiding significance for the later exploration and development of weathered volcanic hydrocarbon reservoirs.
