双台子油田低阻油气层判别方法研究

Research on Identifying Method of Hydrocarbon Reservoir with Low Resistivity of Shuangtaizi Oil Field

双台子油田东营组油气层由于受岩性细、地层水矿化度高、束缚水饱和度高等因素的影响,造成电阻率值低,测井解释结果偏低,油、气、水层识别难度大。运用油气成藏机理、电性图版识别技术、低电阻形成理论及储层精细对比技术对双台子东营组油气层进行识别,取得了较好的效果。

Dongying group of Shuangtaizi oil field is influenced by the factors of fine lithology,high mineralization of formation water,high saturation of bound water,which causes low resistivity value,low log interpretation result,difficult identification of oil,gas,aqueous layer.Dongying group hydrocarbon reservoir of Shuangtaizi oil field was identified by using mechanism of hydrocarbon reservoirs,electrical plate recognition technology,formation theory of low resistance and technology of fine reservoir contrast,which achieved better results.
