Comprehensive Evaluation of Gas Zone in Multi-Layer Sandstone Gas Reservoir

Article Preview

Abstract:

This work, in view of the features of strong gas zone heterogeneity in Multi-Layer Sandstone Gas Reservoir (MLSGR), develops a methodology on Comprehensive Evaluation of Gas Zone (CEGZ). By using of the methodology, three grade gas zone classified score bounds were transformed from three grade field production capacity classified criteria by utilizing multi-factor comprehensive evaluation method in terms of analytical hierarchy process and comprehensive scores, and CEGZ of 13236 well-layers in Sebei MLSGR, Qaidam basin were fulfilled successfully, which lays the geologic foundations for subsequent balanced and fine exploitation of Sebei MLSGR, and validates the applicability and reliability of this methodology synchronously.
