| Zusammenfassung: | The invention discloses a method for calculating a three-dimensional expansion form of a segmented multi-cluster fracturing crack of a horizontal well. The method comprises the following steps: acquiring stratum parameters, fracturing construction parameters and engineering parameters; establishing a horizontal well segmented multi-cluster fracturing crack full-three-dimensional model under the induced stress interference, wherein the horizontal well segmented multi-cluster fracturing crack plane full-three-dimensional model under the induced stress interference comprises a multi-cluster fracturing crack plane full-three-dimensional model and an induced stress model; and according to the stratum parameters, the fracturing construction parameters, the engineering parameters and the horizontal well segmented multi-cluster fracturing fracture plane full-three-dimensional model under the induced stress interference, the target fracture three-dimensional expansion form under the induced stress interference is dete |
