Experimental Study of Well Deviation Correction Model in Deviated and Horizontal Wells Production Profile

Liu, Jun-Feng / Guo, Hai-Min

There are big difference of fluid flow patterns between horizontal wells and vertical wells, so the current interpretation models of production logging multiphase flow in vertical wells are not suitable for data interpretation in highly deviated and horizontal wells. In this paper, firstly, the two-phase flow (oil-water and gas-water) simulation experiments have been carried out in large-diameter (0.124 meter internal diameter) uphill, horizontal and downhill Plexiglas pipe with practical production logging tools. Secondly, based on the conclusions of fluid flow mechanism from experimental data analysis, and considering the affecting factors (i.e. Logging tool and well deviation), we have obtained slip velocity model after well deviation correction in highly deviated and horizontal wells, which have been corrected by the mature interpretation models. Finally, this proposed method has been proved correct and feasible through the experimental data validation.
