The Effect of Hydraulic-Natural Fracture Networks on the Waterflooding Development in a Multilayer Tight Reservoir: Case Study

Figure 11

The water breakthrough controlled by the fracture networks in the C6^1-2-3 sand layer. The light blue circle denotes the cumulative injection volume of injection wells. The short line overlapped the production wells show the hydraulic fractures. The long blue belt illustrates the combined hydraulic-natural fracture. The base map was the microfacies in the C6^1-2-3 sand layer.
