The method is presented to determine formation average pressure and boundarypressure with threshold pressure gradient and injection-production ratio.
给出了考虑注采比和启动压力梯度的平均地层压力和边界压力的确定方法。

The flow parameters such as discharge, free surface profile and boundarypressure distribution are simulated by numerical calculating the boundary integral equations.
通过数值求解边界积分方程组，对流量、水面线和边壁压力等水力参数进行了数值模拟。
