Abstract The reservoir productivity index depends on the performance of fluid flow through the perforation tunnels. Experimentally, it is observed that higher fluid flow rate occurs in perforation by drilling (PD) technique than the traditional shooting technique. This behavior is favorable for the increased hydrocarbon production from a formation. The better understanding of formation damage mechanisms for various reservoir conditions can be optimized for the economic benefits and managerial decision. The perforation by drilling technique is proposed as an alternative perforation technique since this technique induces less formation damage. Experimental and numerical investigations are ongoing research in this regards. The primary results of the two-phase fluid flow through a perforation tunnel of porous media are modeled using ANSYS CFX-15.07 platform. The numerical data are validated with the experimental data. The effects of different petro-physical properties such as permeability, porosity, fluid viscosity, flow rates, and injection pressure are analyzed in the simulations.

射孔洞两相流体流动数值研究

摘要 储层产能指数取决于流体通过射孔隧道的性能。实验表明，钻孔射孔 (PD) 技术比传统的射孔技术具有更高的流体流速。这种行为有利于增加地层的烃产量。更好地了解各种储层条件的地层损伤机制可以优化经济效益和管理决策。钻井技术穿孔被提议作为替代的穿孔技术，因为该技术引起的地层损伤较小。实验和数值研究正在进行这方面的研究。两相流体流过多孔介质穿孔隧道的主要结果使用 ANSYS CFX-15 建模。07平台。数值数据与实验数据进行了验证。在模拟中分析了不同岩石物理特性的影响，例如渗透率、孔隙度、流体粘度、流速和注入压力。
