Fracturability evaluation of conglomerate reservoirs in the Kongdian Formation of the Bozhong Sag
摘要
Abstract
Offshore low-permeability oil and gas reservoirs represent critical domains for reserve expansion and production enhancement during China's14th Five-Year Plan.Yet,achieving commercial productivity and enabling effective reserve development typically necessitates fracturing stimulation.Consequently,reser-voir fracturability evaluation holds paramount significance for productivity prediction,fracturing decision-making,layer/interval selection,and optimization of fracturing process parameters in these reservoirs.Guided by an integrated geological-engineering research framework,this study focuses on the conglomerate reservoirs of the Kongdian Formation in the Bozhong Sag.Employing Grey Relational Analysis(GRA)and Analytic Hierarchy Process(AHP),it identifies 12 key parameters for characterizing geological and engi-neering sweet spots in low-permeability conglomerate reservoirs.A reservoir classification method for the Kongdian Formation conglomerates in the Bozhong Sag is established based on fracturability evaluation.Findings reveal that Class Ⅲ reservoirs can undergo commercial development via fracturing stimulation under current technical regimes,designating them as primary targets for subsequent reserve and production growth in offshore low-permeability conglomerate reservoirs.关键词
