  • Method for determining vertical well stratified fracturing crack lengths based on interlayer equilibrium displacement
    Patent number: 11702933
    Abstract: The invention discloses a method for determining vertical well stratified fracturing crack length based on interlayer equilibrium development. According to the method, interlayer equilibrium development can be achieved by determining the crack length of fracturing of each layer in the condition that an oil well meets the productivity requirements. The method comprises the following steps: 1) a threshold pressure gradient of each layer is determined; 2) a relationship chart of the crack half-length xf and the equivalent well diameter rwe is established; 3) daily oil production rate per unit thickness Qc meeting the production requirements is calculated; 4) the equivalent well diameter rwe of each layer is calculated according to the daily oil production rate Qc; and 5) the crack half-length xf of fracturing of each layer is calculated according to the equivalent well diameter rwe of each layer.
