Abstract

Dina 2 Gasfield is an ultra-high pressure,low-permeability fractured condensate gas reservoir with high heterogeneity.The relationship among single well production, fractures and physical properties of the matrix is analyzed by core, logging and test data.On the basis of the results,development wells are divided into 3 classes by using Q-type cluster analysis, synthesizing thickness of fractured intervals,fracture density, fracture aperture and KH value of matrix. Taking the classified gas wells as samples, classification discriminant function is established based on linear regression, and its results are in agreement with the ones of clustering method.Therefore, the results provide a reasonable basis for productivity classification evaluation and policy making of development technology in Dina 2 Gasfield.
