试采井流入动态曲线分析及合理流压的确定

Analysis of Inflow Performance Relationships Curves of Producing Well and Determination of the Reasonable Flow Pressure.

根据现场试验的试采井资料,绘制油井流入动态曲线,分析研究其变化规律,并给出确定试采井合理流压的方法。分析得知,试采井合理井底流压不应低于流入动态曲线第一个拐点对应的压力。

In terms of the producing well data by fields' experiments, the paper has drafted the inflow performance curves, analyzed and researched the change rule, and given the methods by determined the reasonable flow pressure of producing well. It can get the conclusion that the reasonable flow pressure of producing well should not be lower than the pressure corresponding to the first inflexion point of the inflow performance curve.
