摘要：The main thick reservoir of Lamadian oilfield has entered the production decline stage. Sheet differential reservoir and the untabulated reservoir has become the main replacement target of the old oil fields. This paper makes use of core analysis data of 6 closed coring Wells that have been drilled in recent years. The parameters such as porosity, permeability, saturation, washing conditions, oil displacement efficiency and recovery degree were counted in the oil formation. The operational characteristics of different types of untabulated reservoirs are clarified. It provides a new geological basis for the development and adjustment of untabulated reservoirs.
