摘要
采用油基泥浆取心或压力密闭取心直接测定样品的含流体饱和度是目前最准确的方法,也是建立其他间接方法的基础,但在中—低砂岩渗透储层领域,这种直接取心测定工艺技术却出现了问题。研究和改进用密闭取心样品直接测定原始含油饱和度的工艺、创新和开发用普通岩心(包括岩屑、井壁取心)测定含流体饱和度的技术和方法,以准确的岩心分析含流体饱和度数据标定建立地球物理测井和实验油藏工程等间接计算方法是今后研究砂岩储层油藏原始含油饱和度的发展趋势。
At present, the most accurate way to directly determine liquid saturation and also the basis of establishing others indirect methods are coring in oil-based mud and pressure sealed coring. But in the field of medium-low permeability sandstone reservoirs, the above direct coring technique appears problem. So the following development trends toward original oil saturation study in sandstone reservoirs prove obvious： direct technology to study and improve sealed coring sample; technique and method by innovated and developed common coring including rock cutting and sidewall coring; indirect methods containing the built geophysical logging and experimental oil reservoir engineering by accurately analyzing the bound fluid saturation data calculation.
