pressure characteristics and Effective Deployment in a water bearing tight gas reservoir with low velocity non darcy flow
Energy & Fuels, 2011Co-Authors: Hongqing Song, Xiaohe Huang, Dongbo HeAbstract:An experimental investigation of existing conditions of the threshold pressure gradient (TPG) for gas flow in water-bearing tight gas reservoirs was made and discussed, using cores at different water saturations prepared from the Sichuan gas field in China. The existence of TPG was proven, and the relationship between TPG and water saturation and absolute permeability were obtained by laboratory tests. TPG increases with higher water saturation and lower absolute permeability. Consequently, a mathematical model of low-velocity non-Darcy gas flow was established on the basis of conservation of mass and momentum equations. According to the analytical solution of non-Darcy radial flow derived here, an easy and accurate calculation method of the control radius is presented, which is most popular with reservoir engineers. Factors, such as TPG and isothermal compressibility, on Effective Deployment were also discussed. The analysis of calculation results demonstrates that peripheral reserves of the wellbore are...

A Study of Effective Deployment in Ultra-Low-Permeability Reservoirs With Non-Darcy Flow
Petroleum Science and Technology, 2010Co-Authors: Hongqing Song, Weiyao Zhu, M. Wang, Y. K. Sun, Xiao ChenAbstract:Abstract Due to the existence of a threshold pressure gradient (TPG) in ultra-low-permeability reservoirs, the peripheral reserves of the wellbore are difficult to deploy Effectively. The main problem is that it is hard to ensure that well pattern, well spacing, and drawdown pressure easily and accurately because of the existence of low-velocity non-Darcy flow in such reservoirs. Simple and accurate calculation methods of the problem are most popular with reservoir engineers, so Effective Deployment calculation methods of ultra-low-permeability reservoirs are presented in this article. They include control radius calculation, control distance calculation, control area calculation, and control coefficient calculation, which can be directly used in the evaluation of well pattern thickening of developed oilfields and reserves of undeveloped oilfields. Based on theory of fluid mechanics in porous medium considering TPG, the non-Darcy flow mathematic model was established to reveal the characteristics of press...
