Analysis of the Fluid Flow Field Near Wellbore Wall of
Gas-well Perforated Completion in Yuanba

doi:10.3863/j.issn.1674–5086.2013.06.024

Abstract

Abstract:

The wells in Chuandong Yuanba are mainly extra-depth horizontal gas wells. Because the density，viscosity and
compressibility coefficient of nature gas vary with the temperature and pressure，the problems of the fluid flow field near
wellbore wall of the gas-well perforated completion are not solved with the analytical method. In the paper，the 3D fluid
flow finite element model（FEM）near the wellbore wall is established with the COMSOL Multiphysics software. The model
includes the wellbore size，perforation depth，perforation diameter，perforation density，phasing angle，drilling damage degree，
permeability，gas density，viscosity as well as compressibility coefficient，and so on. We can change the arbitrary parameter
to get the distribution of the fluid flow field near the wellbore wall. Based on the fluid flow model in the paper，the reciprocal
interference near wellbore fluid flow field under the different phasing angles and different perforation density was analyzed in
details. It provides the theoretical supports for the optimal design of the perforated completion parameters in horizontal gas
well.

Key words: horizontal gas well, perforated completion, near the wellbore wall, analysis of the fluid flow field, FEM
