Abstract
The present invention belongs to the technical field of oil and gas engineering, and discloses a method of artificially assisted filling for sand control and water control of a fractured reservoir and a method for evaluating a filling effect. The method of artificially assisted filling for sand control and water control of the fractured reservoir comprises the steps: S11, calculating a fracture productivity evaluation index F of the fractured reservoir; S12, calculating an implementation feasibility index G of an artificially assisted filling process; S13, based on the fracture productivity evaluation index F obtained in step S11 and the implementation feasibility index G of the artificially assisted filling process obtained in the step S12, selecting one of a natural micro-saturation filling process, an artificially assisted extrusion supersaturation filling process or an artificially assisted fracturing strong saturation filling process for filling.
