On the Relation between Pre-fracture Growth and Productivity of Volcanic Reservoir in Xingcheng Area

Qualitative or quantitative evaluation of productivity for oil and gas reservoirs was a basis task for oil exploration and development. In allusion to the characteristics of multi-types, complex pore structures, strong reservoir heterogeneity of volcanic reservoirs in Xfingcheng Area of Xushen Gas Field, on the basis of analyzing the geology of volcanic reservoir and gas test data, the total porosity, secondary porosity, the secondary thickness, the range of pore and fracture were denoted by using conventional and imaging logging data. A criterion was established for productivity evaluation of volcanic reservoirs by using the parameters stated above. It is used with satisfied result, it is a valuable reference for productivity prediction and arrangement of gas field development for volcanic reservoirs.
