Problems solved by technology

[0003] However, the cost of proppant is relatively high. If a large amount of proppant is used in the fracturing process, the cost of fracturing will be increased. If the rock inside the fractured wellbore can be displaced by itself, or the cuttings can be self-supported to fill the fracture. , you can reduce the use of proppant, thereby reducing the cost of fracturing

Abstract

The present application provides a wellbore fracturing analysis method. The method includes: inputting the data to be analyzed of the target fractured well section into the rock mechanics model to obtain the first parameters of the target fractured well section; obtaining weight data, the weight data including each of the first parameters The weight of the parameter; determine the location information of the crack initiation point according to the first parameter and the weight data. The wellbore fracturing analysis method of the present application can ensure that the rocks inside the wellbore are dislocated, or cuttings Self-supporting achieves the function of filling fractures, thereby reducing the use of proppant during wellbore fracturing and reducing the cost of wellbore fracturing.

Description

technical field [0001] The present application relates to rock mechanics measurement technology, in particular to a wellbore fracturing analysis method, device, electronic equipment and computer storage medium. Background technique [0002] Fracturing refers to a method of using hydraulic action to form fractures between the oil layer and the gas layer inside the wellbore during the oil or gas recovery process. When fracturing, it is necessary to squeeze high-pressure, large-displacement, and certain-viscosity liquid into the oil layer. After the oil layer is pressed out into many cracks, proppant such as quartz sand is added to fill the cracks to improve the permeability of the oil layer. Increase oil production. [0003] However, the cost of proppant is relatively high. If a large amount of proppant is used in the fracturing process, the cost of fracturing will be increased. If the rock inside the fractured wellbore can be displaced by itself, or the cuttings can be self-...
