| 摘 要： | 笔者利用地面及地下的笔管压力资料，定量对比了地面，地下储层的物性特征。通过研究对比认为，在围限压力作用下，储层的孔，渗性，排驱压力，饱和度中值压力，大孔喉所控制的孔隙体积百分比，喉道半径均降低，但孔喉分选变好。该项成果有利于提高储量计算的精度，确定地层条件下流体的渗流特征。

| Abstract: | A quantitative correlation of physical properties of the surface and subsurface hydrocarbon reservoirs in one oilfield in western China was made in the light of the data on the surface and subsurface capillary pressures. The results of research show that the porosity, permeability , delivery pressure, median saturation pressure, percentage of pore volumes controlled by pore throats, and throat radius tend to decrease under the influence of confined pressures, while the sorting of pore throat tend to be much better. The present study will help improve the precision of reserve calculations and identify the seepage flows in the strata. |
