Impact and evaluation of wellbore fluid and drilling parameters on horizontal well hole cleaning
Based on the impact of cutting bed height and drilling pipe eccentricity on horizontal well geometries, an iterative solution process is presented to solve double-layer model.And then a novel index is introduced to compare the sensitivity.The result indicates: Cutting bed height decreases as drilling fluid density and pump rate increases;Cutting with high density is adverse to hole cleaning;There is an optimal cutting particle size for hole cleaning;Cutting bed height enhances as ROP increases;Larger size of drilling string and small size of wellbore have advantage on cutting transport.The sensitivity decreases as the following sequence: drilling fluid density, pump rate, cutting particle diameter, wellbore diameter, drilling string diameter, rate of penetration and cutting density.
