一种调控油藏采油功能菌细胞表面疏水性的方法
摘要：
本发明属于生物技术领域，具体涉及到一种调控油藏采油功能菌细胞表面疏水性的方法。该方法具体包括以下步骤：试验油藏中采油功能菌的检测；采油功能菌的培养；采油功能菌细胞表面疏水性的测定；采油功能菌细胞表面疏水性的调控；物理模拟驱油效果的评价。本发明能有效提高采油功能菌细胞表面疏水性，CSH值达到80%以上；同时具有操作简单、易于实现和效果显著的特点，物理模拟实验提高采收率大于15%。因此，本发明可广泛地应用于内源微生物驱油现场试验中。
摘要（英）：

The invention belongs to the biotechnical field, and concretely relates to a method for regulating the cell surface hydrophobicity of oil recovery functional bacteria in an oil reservoir. The method concretely comprises the following steps: detecting the oil recovery functional bacteria in the test oil reservoir; culturing the oil recovery functional bacteria; determining the cell surface hydrophobicity of the oil recovery functional bacteria; regulating the cell surface hydrophobicity of the oil recovery functional bacteria; and evaluating the physical simulation oil displacing effect. The method can effectively improve the cell surface hydrophobicity of the oil recovery functional bacteria to make the CSH value reach 80% or above, has the characteristics of simplicity in operation, easiness in realization and significant effects, and improves the recovery rate of physical simulation experiments by above 15%. The method can be widely applied to onsite test of endogenous microbial oildisplacement.
