油藏岩石的润湿性毛管力和相对渗透率驱替-吸吮循环分析

DRAINAGE-IMBIBITION CYCLES OF WETTABILITY, CAPILLARY PRESSURE AND RELATIVE PERMEABILITY OF OIL RESERVOIR ROCK

对油藏岩石的润湿循环、毛管力和相对渗透率循环进行了综合对比,阐明了它们之间的共同点和内在联系。并指出在油藏工程应用上必须考虑三者的一致性以及它们之间的联系。结合实例论述了这三种循环用于评价钻井液对储层伤害的程度。

The drainage-imbibition cycles of wettability, capillary pressure and relative permeability were described.There is something common among the cycles of these parameters and their interrelationship can be established, which must be taken into consideration in their application to reservoir engineering. Some examples of the use of these three cycles in the evaluation of the formation damage by drilling fluid were given.
