西峰油田西259井区长3(下标 2)特低渗储层测井二次解释研究

Recently, very-low-permeability reservoirs have become exploration targets in China, so it is important to precisely evaluate such complicated reservoirs for a stable oil production. This paper analyzes the genesis of Chang-3(subscript 2) very-low-permeability reservoir in Xi-259 Well, based on core observation and chemical assay data, applies ”core scaling logging” to re-establish a model of porosity, permeability and oil saturation, and carries out the second interpretation on logging, which meets the requirements of the reservoir development and provides a reference in studying and developing such very-low-permeability reservoirs.
