摘　　要：老油田由于开发年代久远、测井系列老、水淹特征复杂等实际情况,给测井二次解释带来了很大的困难。以老君庙油田L油藏为研究对象,利用地质统计学领域的变差函数块金效应对电阻率曲线进行标准化。采用沉积相控下的电阻率建模思路,建立了不同沉积环境的储层属性模型并进行测井解释。利用常规曲线组合进行水淹层定性识别,通过联立方程组的方法进行水淹层定量评价。经试油生产验证,解释成果准确性较高,为油田落实石油地质储量以及编制开发方案提供了依据。Secondary log data interpretation of old oilfields has many difficulties due to long time development history, old logging tools and complicated water flooding characters. With reservoir- L in I.aojunmiao oilfield as an example, variation function nugget effect in the geological statistics is used to standardize resistivity curves. On this basis, property models in different sedimentary environments are established through the method of resistivity modeling under the control of sedimentary facies. Finally, the water-flooded layer is recognized quantitatively through ordinary curve combination and then evaluated quantitatively through simultaneous equations. Oil production tests show much accurate interpretation results, therefore providing evidence for surveys of petroleum geological reserves and establishment of development project.
