WELLPLAN Hydraulic Analysis ;Contents ;Topics Discussed in the Module;Objectives ;Hole cleaning model is based on empirical relationships coupled with analytical formulations Basis for frictional pressure loss calculations using Rheological models （流变模型）such as Bingham Plastic, Power Law（幂律）, Newtonian, Herschel-Bulkley, and Generalized Herschel-Bulkley. Swab/Surge calculations based on conventional steady-state model（稳定模型）. Effect of wellbore circulating temperatures on fluid properties are based on transient models. Pipe roughness and eccentricity calculations for Herschel-Bulkley are based on empirical correlations. Pressure drops across mud motors, MWD’s, split flow（分流） components such as under reamers and hole openers are accounted. ;Drilling;Analysis process;When Should I Use Hydraulics Module;Introduction and Concepts;Classical Methods of bit jet optimization: 4 calculation methods Maximum hydraulic horsepower Maximum bit jet impact force Maximum nozzle velocity Percent system pressure loss at the bit 1 method uses actual rig circulating pressures Graphical methods ( Bit Vendor Optimization May Be Rqd.)
