Logging subdivision interpretation technology for thick oil layers in peripheral oilfields of Daqing Placanticline
摘要
Abstract
In order to meet the demand of logging subdivision interpretation of thick oil layers in peripheral oilfields of Daqing Placanticline,and to solve the problems of complex oil and water layers identification and subdivision in-terpretation of thick oil layers in peripheral area of Placanticline,on the basis of supplementing and improving the original reservoir parameters interpretation model,deep lateral resistivity correction model is established,which adopts"four separation"method of areal zones partitioning,vertical layers separation,reservoirs classification and layers thickness dividing,as well as"1C4 I"parameters for fine identification method of oil and water layers,includ-ing comprehensive index,oil-bearing property index,water-bearing property index,pore property index and oil-wa-ter ratio index.Productivity prediction model for Putaohua reservoir in Shengping Oilfield is established,forming supporting technique for fine interpretation of complex reservoirs in low saturation reservoirs.Subdivided layers in-terpretation software based on GPTLog platform and CIFLog platform is developed according to the principles of"subdivision with interlayers,subdivision with different physical properties and subdivision with different watered-out levels(different electrical properties)".Effective identification of complex oil and water layers and automatic subdivision of multiple wells are achieved,forming supporting technique for logging subdivision and interpretation of thick oil layers in peripheral oilfield of Placanticline.The research realizes efficient subdivision and interpreta-tion of thick oil layers in peripheral oilfields of Placanticline,and provides reference for fine interpretation of low saturation reservoirs.关键词
