چکیده
|
The bottom-hole pressure response which can reflect the gas flow characteristics is important to study. a mathematical model for description of gas from porous coalbed methane (cbm) reservoirs with complex boundary conditions flowing into horizontal wells has been developed. meanwhile,basic solution of boundary elements has been acquired by combination of lord kelvin point source solution,the integral of bessel function,and poisson superimpose formula for cbm horizontal wells with complex boundary conditions. using this model,type curves of dimensionless pressure and pressure derivative are obtained,and flow characteristics of horizontal wells in complex boundary reservoirs and relevant factors are accordingly analyzed. © 2015 cheng-yong li et al.
