| 摘 要： | 毛管压力曲线反映了在一定驱替压力下水银可能进入的孔隙喉道的大小及这种喉道的孔隙容积,因此应用毛管压力曲线可以对储集层的孔隙结构进行研究,进而研究储层的微观非均质性。对商河油田沙一中典型的压汞曲线在形态上进行了详细分析,编绘了所有岩样的毛管压力曲线、J函数曲线与孔径分布和渗透率贡献曲线,研究认为,商河油田沙一中储层的微观非均质性相当严重。

| Abstract: | As capillary pressure curve reflects the size and volum of pore - throat under some displacement pressure of mercury, it can be used to carry out research first on the reservoir pore structure and then on the microcosmic reservoir heterogeneity. According to the detailed analysis of typical mercury pressure curves of the Shanghe oilfield, the capillary pressure curves of all bore specimens, J function curve, pore diameter distribution and permeability - contributing curves were copy - edited. The results show that the microcosmic reservoir heterogeneity of Sha 1 in Shanghe oilfield is quite poor. |
