应用多层油藏三相流入动态优化采油井流压

Optimization for Flowing Pressure of Oil Production Well Using Three Phases Inflowing Performance of Multi-layer Reservoir

推导了适用于油、气、水三相的流入动态方程,并根据多层油藏油井流入动态理论,对多层油藏油井的层间流入动态差异进行分析,得出层间不同的流压及含水对全井产液的影响规律,从而指导油井工作制度的优化。

This paper has derived the inflowing performance equation that is suitable for three phases of oil,gas and water.According to the inflowing performance theory on the oil well of multi-layer reservoir,it analyzes the difference inflowing performance among layers of the oil wells.The influence law of different flowing pressure and holding water among layers on produced liquid is obtained,which can guide the working system optimization of oil well.
