WETTABILITY AND ENHANCED OIL RECOVERY OF TIGHT OIL RESERVOIRS

非常规资源，如重油、沥青和致密油(致密油)中的常规石油，正成为加拿大人的主要原油来源。因此，申请人的研究计划围绕着对这些资源的最佳利用展开。这项提议涉及需要研究致密油的驱替和生产机制。为研究致密油藏中的界面和驱替现象，提出了利用多物理软件和基础实验相结合的方法建立致密油藏界面和驱替的基本模型。该模型将描述具有吸附和/或冷凝作用的介质中的孔隙度、渗透率、电阻率、毛管压力和相对渗透率等岩心分析属性。此外，还将调查在紧凑媒体中的吞噬过程。

Unconventional resources such as heavy oil, bitumen and conventional oil from tight reservoirs (tight oil) are becoming the primary source of crude oil for Canadians. As such the applicant's research plan evolves around the optimum exploitation of these resources. This proposal addresses the need to study mechanisms of displacement and production of tight oil. It is proposed to construct fundamental porous media models using multi-physics software and fundamental experiments with reservoir rock to study interfacial and displacement phenomena in tight oil reservoirs. The model will describe core analysis properties such as porosity, permeability, resistivity, capillary pressure, and relative permeability in media with adsorption and/or condensation. Also the process of imbibition in tight media will be investigated.
