Methods for enhancing and maintaining effective permeability of induced fractures

摘要

Systems and methods for treating subterranean formations for treating subterranean formations using propellant fracturing and hydraulic fracturing to detonate and inject in sequential stages. A method comprises disposing a propellant fracturing tool downhole into a well bore; introducing a fracturing fluid into a work string coupled to the fluid conduit to pressurize and set an upper packer and a lower packer against the well bore; detonating sequentially a plurality of propellant band stages to produce one or more fractures; introducing sequentially a series of treatment fluids into a well bore penetrating at least a portion of a subterranean formation, wherein the sequential introduction of the series of treatment fluids occurs between the sequential detonation of the plurality of propellant band stages; and depositing at least a portion of the treatment fluids in at least a portion of the subterranean formation.
