The low permeability reservoirs have the start-up pressure, and the seepage flows do not obey the Darcy's law.

低渗透油藏渗流时存在启动压力现象，其渗流特征不遵循达西定律。

The results showed that mobility and start-up pressure gradient are the main reasons of non-linear seepage flow effect.

结果表明流度与启动压力梯度是形成非线性渗流的主要因素。

The method can be used to calculate the the end time of effect of wellbore storage with start-up pressure gradient considered.

该方法可用于考虑启动压力梯度影响的低渗透气藏气井井筒储集效应结束时间的计算。

Paul Zwillenberg, managing director, says the typical start-up's financing cycle has greatly shortened, putting new pressure on firms to grow quickly.

Moreover, working with other start-ups in close quarters pushed PlanGrid to keep up thanks to peer pressure and their internal drive.
