摘要
通过特制的含油岩石薄片研究,使其油层孔渗性、油水存在的微观特征、含油饱和度、残留油的存在状悉、驱油效率的高低及其影响因素等均能最清晰而又直观地展现出来,能为制定油藏开发方案或进一步提高油层采收率、选择有效的增产措施提供可靠依据。
A study on oil-bearing rock thin sections made in a special way can desplay directly theporosity and permeability of oil reservoirs, the microscopic features of the presence of oil and water, theoil-bearing saturation, the existence state of the remnant oil, the oil dirving efficiency and its relevantinfluential factors, etc., thereby providing a reliable basis for working out an oil-developing plan, forraising recovery ratio of oil reservoirs, and for adaptable measures to increase production.
