And based on the relations of compressibility factor and viscosity of the gas versus pressure, the relations of these parameters versus dimensionlesspressure are also built.
同时通过对气体压缩因子、黏度随压力、温度的变化，建立了这些参数和无因次压力的关系；
2
The dimensionless average formation pseudo pressure is directly proportional to the dimensionless producing time if the influence of wellbore storage coefficient and skin factor is neglected.
在不考虑井筒储集系数和表皮系数影响的情况下，无量纲平均地层拟压力与无量纲生产时间成正比。
3
On the basis, the influence of dimensionless apparent permeability variation factor and mobility ratio to pressure behavior has been analyzed.
