Refracturing production method

The invention discloses a refracturing production method. The method comprises the steps that fracturing is conducted on an old joint of a target well, and the old joint is fractured to form an old joint net containing main cracks and branch cracks; energy storage fluid is injected into the target well through the old seam net, and a high-pressure area is formed around the old seam net; a seam temporary plugging material is injected into the target well after energy storage is completed to plug the seam of the old seam; new fracture section fracturing is carried out on the target well after old fracture opening plugging is completed, and a new fracture network containing main fractures and branch fractures is formed; and opening the well for production when the old seam opening is still in the blocked state, unblocking the old seam opening when the pressure of the old seam net and the pressure of the new seam net are equal during production, and producing the new seam net and the old seam net together. 本发明公开了
