starting pressure gradient的意思|示意

And the same time the lower permeability is the greater starting pressure gradient and the more slow speed of pressure conduction is.

且渗透率越低，启动压力梯度越大，压力传导速度越慢。

At present, the studies of starting pressure gradient in home and abroad are main focus on single phase and water-oil two-phase and there are a few studies of gas-oil two-phase.

目前，国内外对启动压力梯度的研究主要集中在油水两相中，对于油气两相启动压力梯度研究很少。

The finite difference method is used to solve the coupling model, and the influence of starting pressure gradient on the distribution of groundwater pollutant concentrations is analyzed.

采用有限差分法和混合有限分析法对耦合模型进行数值求解，并分析了启动压力梯度对地下水污染浓度的影响。

The effects of reservoir fluid property in high and low pressure and the starting pressure gradient on the percolation laws were taken into account in this model.

给出了极限井底流压和产量拐点的求解方法，分析了启动压力梯度、流体性质等因素对低渗透油藏油井产能的影响。

The testing results of a low permeability reservoir indicate that this IPR equation can effectively evaluate the impact of starting pressure gradient on inflow performance.

某低渗透油田的测试分析结果表明，该IPR方程能有效评价启动压力梯度动态变化对油井动态的影响。

Experiments show that a low permeable reservoir has a starting pressure gradient, and therefore different seepage rule from that of middle and high permeable reservoirs.

实验表明，低渗透油藏具有启动压力梯度，因此其渗流规律与中、高渗透油藏不同。
