Production prediction for fracture-vug carbonate reservoirs using electric imaging logging data
摘要
Abstract
Considering the fluid flow non-darcy characteristics in fracture-vug carbonate reservoirs,a new multi-scale conduit flow model production prediction method for fracture-vug carbonate reservoirs was presented using image segmentation technique of electric imaging logging data.Firstly,based on Hagen-Poiseuille's law of incompressible fluid flow and the different cross-sectional areas in single fractures and vugs in carbonate reservoirs,a multi-scale conduit flow model for fracture-vug carbonate reservoir was established,and a multi-scale conduit radial fluid flow equation was deduced.Then,conduit flow production index was introduced.The conduit flow production index was calculated using fracture-vug area extracted from the result of electrical image segmentation.Finally,production prediction of fracture-vug carbonate reservoir was realized by using electric imaging logging data.The method has been applied to Ordovician fracture-rug carbonate reservoirs in the Tabei area,and the predicted results are in good agreement with the oil testing data.关键词
