摘要： Systems and methods identify and/or detect one or more features of a well casing by utilizing one or more downhole measurements obtainable by a downhole component. The one or more features of the well casing are identifiable and/or detectable from the one or more measurements associated with one or more properties of the one or more features of the well casing. The one or more measurements for indentifying and/or detecting a presence and/or a location of the one or more features of the well casing include sonic measurements, nuclear measurements, gamma ray measurements, photoelectric measurements, resistivity measurements and/or combinations thereof.
摘要翻译： 系统和方法通过利用由井下部件可获得的一个或多个井下测量来识别和/或检测井套管的一个或多个特征。 井套管的一个或多个特征可以从与井套管的一个或多个特征的一个或多个特性相关联的一个或多个测量值中被识别和/或检测。 用于识别和/或检测井壳的一个或多个特征的存在和/或位置的一个或多个测量包括声波测量，核测量，伽马射线测量，光电测量，电阻率测量和/或其组合。
