查询词典 brittle

Mechanical reason of borehole collapse in brittle shale is researched. With the elastic theory, the formula for calculating the maximum and minimum drilling fluid density that would cause the initial shear fracture in vertical and inclined borehole is derived and the influence of formation non-linear deformation property is taken into account. The solution of the formula is given by iteration method.
