在石油工业中,测定管外环形空间水泥顶面、评价注水泥作业的质量有多种方法,最初用注入法和循环法,后来用各种电法测井.井温测井是目前测定水泥顶面常用的方法.在特定的情况下,也可采用放射性示踪测井和声波测井,但这些方法只能指示有无 In the petroleum industry, there are many ways to measure the quality of grouting cement in the annular space outside the pipe, initially using the injection method and the circulation method, and later using various electrical methods to log the well temperature logging which is currently used to measure the cement Top-of-the-line methods. In specific cases, radiotracer and sonic logging may also be used, but these methods only indicate whether
