The transporting mechanic of slurry of Heavy oil and sand in horizontal wellbore
It is a special modality of solid-fluid conduit flow for the sand transporting procedure in wellbore.Under the action of heavy oil,because of the difference of the borehole location,the transporting mechanic of sand is not the same.For the vertical wellbore,sand particles are mainly dominated by the drag forces and carried out of the hole; however,for the horizontal wellbore,sand particles are under complex forces and show different flow state.In different flow state,the sand particles are controlled by different forces,the heavy oils sand transporting capacity is changed.This paper begins with the analysis of the stress of the sand particles,and deeply analyses the vertical and horizontal wellbore,the stress of sand particles in the heavy oils sand mixing flow procedure,and then study the heavy oils sand transporting capacity.
