Abstract
In this paper, a numerical study is carried out on the perforation pipes with phase angles of 180° and 90° in a horizontal wellbore. To understand the effect of the above two-phase angles on the flow inside the wellbore, the CFD simulation of computational fluid dynamics is used. ANSYS FLUENT's simulation of the flow in the well has been used to calculate the pressure drop, friction factor, wall shear stress, productivity index, etc. The" standard "(k-ε) model has been used to predict the turbulent behavior of radial flow through perforations in the pipe wall. The conclusion showed that the overall pressure drop increase as the flow rate ratio increase which leads to an increase in the radial flow through the perforations, thereby keeping the axial flow through the pipe constant. Therefore, the percentage error of the total pressure drops between the phasing of the 180° and 90° perforations in test 5 is about 5.4 %. In addition, the main flow increases when the flow through the perforation increases, and this leads to an increase in the average of wall shear stress.
