Influence of Radial Flux Inflow Profile on Pressure Drop of Perforated Horizontal Wellbore

Abstract

In this study, the authors have attempted to present five different profiles for a uniform radial influx through a perforated wellbore. The total pressure drop is not only fric tional, accelerational and gravitational pressure drops, but also by the inflow pressure drop that is caused by the inflow through the perforation. The inflow through the well bore model affects the shear stress due to the wall friction. The influence of inflow depends on the flow regime present in the wellbore. Numerical simulations were per formed using ansys fluent 14-cfx, where the governing equations o f mass and momen tum were solved simultaneously, using the two equations of a standard k-e turbulence model. The results proved that the behavior of wall shear stress followed the shape of the radial inflow, i.e., the shear stress increased with the increase of radial flow and decreased with the decrease of radial flow. It was found that the fluid influx has increased the apparent friction factor along the horizontal wellbore, but in some cases the influx is decreased.

The Effect of Distribution of the Perforation Density on the Production Through Perforated Horizontal Wellbore

“…The pressure drop classifies the impact of the perforation Roughness and smooth pipe. The following relationship gives the five pressure drop terms that make up the total pressure drop in a perforated horizontal pipe explained by (Abdulwahid et al 2014) [35].…”

The Experimental and Model Study on Variable Mass Flow for Horizontal Wells With Perforated Completion

“…A considerable number of experimental work on pressure losses of single flow in perforated completed horizontal wells has been published by many scholars, such as Asheim [1] and Su [2][3] of NTNU, Japanese scholar Ihara [4][5][6] ,Yuan [7][8][9][10] of Tulsa, OuYang [11][12][13] of Stanford, Zhou Shengtian [14][15] of CUP(East China),Wang Zhiming [16][17] of CUP(Beijing), Abdulwahid,M.A. [18] of Andhra University(India), Quan Zhang [19] of CUP (Beijing), Weipeng Jiang [20] of Tulsa. There are three shortages of the previous work.…”
