Problems solved by technology

[0003] Therefore, it is necessary to optimize the parameters of the fracturing fractures so that the productivity of the fracturing fractures matches the seepage capacity of the gravel-packed area, so as to give full play to the stimulation effect of the fracturing fractures. However, no effective implementation scheme has been given in the prior art.

Abstract

The invention discloses a method and a device for realizing optimization of fracturing fracture parameters. The method includes: acquiring maximum capacity of a gravel packing area according to pressure drop of the gravel packing area; calculating optimal fracturing fracture parameters according to the acquired maximum capacity of the gravel packing area. According to the scheme, the fracturing fracture parameters are optimized according to the maximum capacity of the gravel packing area to enable capacity of fracturing fractures to be matched with seepage capacity of the gravel packing area, so that capacity improving effect of the fracturing fractures is brought into full play.

Description

technical field [0001] The invention relates to reservoir fracturing and filling technology, in particular to a method and device for optimizing parameters of fracturing fractures. Background technique [0002] Fracturing packing is currently the main stimulation method for sand producing wells. Fracturing packing has dual functions of stimulation and sand control. A fracturing fracture with high conductivity is formed around the wellbore through fracturing, so that the reservoir fluid around the wellbore changes from a plane radial flow to a linear flow, thereby reducing the seepage resistance near the wellbore, and at the same time, gravel packing around the wellbore The area has the function of sand control. Since the gravel packing zone increases the resistance of fluid flowing from the fracture to the wellbore, it has a certain inhibitory effect on the productivity of the fracture. [0003] Therefore, it is necessary to optimize the parameters of the fracturing fract...
