主 题：Low-permeability fractured reservoir fracturing horizontal well interwell connectivity dual media channeling paths
摘 要：Often oilfield fractured horizontal wells produce water flowing in multiple *** this study,a method to identify such channeling paths is *** dual-medium model is based on the principle of inter-well connectivity and considers the flow characteristics and related channeling *** Lorentz curve is drawn to qualitatively discern the geological type of the low-permeability fractured reservoir and determine the channeling direction and *** practical application of such an approach to a sample oilfield shows that it can accurately identify the channeling paths of the considered low-permeability fractured reservoir and predict production performances according to the inter-well connectivity *** a result,early detection of water channeling becomes possible,paving the way to real-time production system optimization in low-permeability fractured reservoirs.
