Investigation of Hydrocarbon Fluid Flow in the Perforated Section of the Oil Well

Perforation is a process of drilling, which is used to pierce a wall tube to pass a fluid stream from an oil reservoir into a well# in this paper the flow of hydrocarbon fluids in the perforated well was modeled using computational fluid dynamics tool# due to the importance of flow regime in the perforation section of oil wells, the velocity and pressure profile of hydrocarbon flow was obtained# the simulated oil well was 5 and 0#5 cm in length and diameter, respectively and the three perforations was created at the bottom of well# the results showed that the oil velocity increased through the perforated sections but remained constant at the well column by keeping the parabolic pattern# due to velocity increasing, the flow pressure was decreased through the perforated sections and well column# the effect of perforations diameter on the productivity index was also investigated# the results showed that by increasing the diameter the flow rate was increased which influenced the well productivity index#
