一种确定吸水剖面的方法探讨

Discussion on new method for determining input profile of injection well

注水井吸水剖面反映地层的吸水能力,常规的研究分层能力的方法是采用生产动态测井技术。由于采集资料时受产量、工艺条件、井况等因素的影响,部分井剖面无法获取,因此提出了一种快速简单的计算方法。只要有电阻率Rt、声波时差△t及砂层厚度h等电测解释成果,即可应用该方法。经大量剖面实例资料验证,该方法是有效可行的。

The input profile of injection well reflects the water-intake capacity of formation. The conventional method for studying the vertical resolution adopts production dynamic logging technique. When acquiring data, the profiles of some wells can not be acquired due to the influence by production, technology and well condition. This paper proposes a fast simple computing method, which can be used just when getting the log interpretation of the resistivity, interval transit time and net sand thickness. The reliability of the method is verified through some practical example data.
