Abstract

Abstract

This paper points out the possible problems in using line sink to describe a horizontal wellbore. It presents a new model to describe a horizontal well with consideration of different flow regions and the laminar and turbulent flow, i.e. linear and nonlinear flow inside the pumping well. Hence, it sets up the inner boundary at a point where water flows out. As it does not need flux or head distribution along the horizontal well, it may avoid the difficulty in using the line sink assumption. This paper uses an "equivalent hydraulic conductivity" concept and its determined approach to treat the horizontal wellbore, which treats the aquifer horizontal well system as a heterogeneous medium with a cylinder lens. It also provides a mathematical model and numerical simulation to solve the flow problem. A sample of a horizontal well pumpage underneath a river is calculated to illustrate the presented model and numerical method and the simulation results of groundwater behavior are indicated.
