大庆外围低渗透储层启动压力梯度研究

The Study of Threshold Pressure Gradient of Peripheral Low Permeability Reservoirs in Daqing

渗流性能是储层评价的一个重要方面。本文在前人研究的基础上,深入研究了低渗透油田中启动压力梯度与储层物性之间的关系,指出启动压力梯度是影响低渗透储层渗流性能的重要因素。对大庆外围低渗透油田的开发具有一定的指导意义。

Leakage is one of the most important part in low-permeability reservoir evalation.On basis of former studies,the factors affect leakage,and the connection between threshold pressure gradient and petrophsical properrities in low-permeability reservoir of outside reservoir of daqing.Point out that threshold pressure gradient is one important factors in affecting the leakage.Exploitation of outside reservoir of daqing oil field can be guided by this.
