Flaky cuttings bed distribution model in a shale gas horizontal well based on experiment and numerical simulation
During the drilling of shale gas wells, the shape of shale cuttings cut by polycrystalline diamond compact bits has an obvious flaky structure. The accumulation of such flaky cuttings is one of the main reasons for high drilling torque and drag and serious back pressure, which affect the drilling sp...
