METHOD OF ARTIFICIALLY ASSISTED FILLING FOR SAND CONTROL AND WATER CONTROL OF FRACTURED RESERVOIR AND METHOD FOR EVALUATING FILLING EFFECT
METHOD OF ARTIFICIALLY ASSISTED FILLING FOR SAND CONTROL AND WATER CONTROL OF FRACTURED RESERVOIR AND METHOD FOR EVALUATING FILLING EFFECT
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.
