Abstract

See full text

The invention relates to a dynamic fracture width calculation method for drilling fluid loss in a fractured formation, which belongs to the field of loss control of drilling and well completion engineering, and includes the following steps: selecting a model according to seismic data and fracture development characteristics and calculating a static hydraulic width of a formation fracture; substituting the static hydraulic width of the formation fracture into a deformation formula of a fracture hydraulic width, to obtain a dynamic hydraulic width of a wellbore fracture; converting the dynamic hydraulic width of the wellbore fracture into an average mechanical width of the wellbore fracture, according to a conversion relational formula of a mechanical width; and solving a mechanical width distribution range of the fracture according to a standard deviation of a mechanical width distribution of a natural fracture.
