Proppant Crushing Mechanisms Under Reservoir Conditions

Proppant Crushing Mechanisms Under Reservoir Conditions

Dec 15, 2018 Proppant crushing, a major proppant failure mechanism, occurs in geothermal energy and oilgas stimulation production stages when the level of net stress exerted on the proppant exceeds the actual crush resistance of the material. Loss of effective reservoir conductivity due to proppant crushing can result in significant loss in productivity, and so it is crucial to understand the realistic ...

Mechanisms of rock cutting

Mechanisms Of Rock Cutting

Crushing bits work by crushing the rock to make an indentation with a tooth and then scouring the rock away with the subsequent tooth movement. The harder the rock the smaller the indentations and the slower the drill rate per revolution. Rocks have a certain threshold pressure which is required to initiate the indentation of each tooth.

Chipping and crushing mechanisms in orthogonal rock

Chipping And Crushing Mechanisms In Orthogonal Rock

In the proposed approach, a rock crushing zone is introduced at the rock-cutter interface beneath the cutters rake face, namely the Tip Crushing Zone TCZ, which, as a destruction kernel, is responsible for both the crushing and chipping phenomena occurring in the cutting process.

Chipping and crushing mechanisms in orthogonal rock

Chipping And Crushing Mechanisms In Orthogonal Rock

Dec 01, 2016 The rock removal mechanism in the rock cutting process includes crushing and chipping failure modes. Crushed and powdery chips are attributed to the crushing mode while chunk-like chips are formed due to the chipping mode. Chipping of rock has been concluded to be caused by either tensile or shear stresses by different researchers.
