注水开发油田水淹油层测井响应特征

Characteristics of well-logging response to water-flooded reservoir in water-driven oil field

油田注水开发后,储层地球物理性质将会发生很大变化.这些由水淹引起的变化能被测井响应所反应,而且能被用于寻找剩余油.通过检查取心井与相邻老井测井响应的对比,分析了油层水淹前后测井响应变化.研究成果对水淹层测井解释及剩余油确定提供了理论基础和实践经验.

The geophysics property of reservoir will have changed largely after water-driving in oil field. The changes caused by water-driving can be shown by well-logging response and be used to locate residual oil. The varieties of well-logging response of water-flooded layer have been analyzed by well-logging comparison of drilling core wells with neighboring wells. The reliable theory foundation and practice experience are provided for water-flooded layer interpretation and residual oil ascertainment.
