Productivity analysis for fractured well in low-permeability gas reservoirs considering slippage effect

A new deliverability equation considering slippage effect for gas reservoirs with low permeability and low pressure

The main factors affecting percolation in low permeability reservoirs include stress,threshold pressure gradient,slippage effect and water-blocking effect,which play various roles on percolation,but all will result in non-linear percolation in the end.

Research on the critical indexs of considering gas slippage effect

Results show that gas slippage effect has a large impact on gas non-linear seepage flow, and with the increa.

Experimental study of gas transfusion with slippage effects in hypotonic coal reservoir

Considering the percolation in this pre-pressing porous media,the slippage effects are remarkable.

Considering the percolation in this pre-pressing porous media,the slippage effects are remarkable,which will increase coal reservoir penetration function.

Numerical simulation of coal-bed methane seepage with the consideration of slip effect and temperature field;

Under this condition, a lot of new influence factors appear, the superficial model of coalbed methane is no longer suitable, so we set up the coalbed methane seepage model considered slip effect and porosity pressure, set up the coalbed methane seepage model considered coupling of s.

The paper studies stress sensitivity and slip effect of CBM reservoir by using low speed permeation experimental unit, and compares the differences of the test results between cores taken from CBM reservoir and sandstone samples.
