Volume fracturing method for reservoir well section under high-density mud drilling well and application of volume fracturing method

The invention discloses a volume fracturing method under a reservoir well section high-density slurry well and application thereof, and the method comprises the following steps: when the direction of a well drilling induced fracture is inconsistent with the direction of an artificial fracture, firstly injecting low-viscosity slick water to make the fracture, then injecting a temporary plugging agent to plug the fracture end, and finally injecting the low-viscosity slick water in a large displacement; and when the trend of the well drilling induced fracture is consistent with the trend of the artificial fracture, low-viscosity slick water is injected in a large-displacement mode to make the fracture. According to the situation that the directions of the well drilling induction crack and the artificial crack are consistent and inconsistent, measures such as in-crack temporary plugging and a variable displacement process are adopted, when the directions of the well drilling induction crack and the artificial cra
