Abstract: Futai buried hill reservoir shows very serious heterogeneity due to existence of complex fractures and pores. The conventional logging interpretation methods are not suitable to this kind of reservoir. The triplicate pore structure interpretation model and corresponding resistivity Logging interpretation model were developed. The calculated triple pore parameters such as fracture porosity,porous fracture and matrix porosity were given. The water saturation in different reservoir space was calculated according to the triple pore parameters. This model and the interpretation method based on this model can correct the errors caused by complex reservoir space and provide a good way to distinguish fluid properties in complex reservoir.

Key words: Futai buried hill reservoir, complex reservoir space, logging, interpretation model, evaluation method

摘要： 分析了富台潜山油藏复杂储层测井解释模型,建立了三重孔隙结构解释模型和电阻率解释模型,求取了三重孔隙参数,并根据三重孔隙在剖面中的变化值,计算了不同储集空间的含水饱和度解释参数,校正了由复杂储集空间引起的含水饱和度的计算误差,从而解决了复杂储集空间流体性质的判识问题。将该复杂储层测井评价方法在富台油田碳酸盐岩潜山油藏进行了检验,取得了很好效果。
