摘要:
俄罗斯原有的水泥密度套管厚度仪(SGDT)固井质量解释方法 仅适用于单层套管的水泥充填状况评价,无法对双层套管固井作业的测井资料进行定量评价。针对Φ2445 mm外管内下入Φ1397 mm套管 的双层套管固井结构,在统计分析62口井的双层套管SGDT实际测井资料的基础上,采用多元非线性回归方法,研究内层水泥密度、外层水泥 密度、井内流体等因素与测井响应之间的关系,得到计算内层套管水泥密度的解释新模型。通过对实际测井资料的处理,验证了解释模型的 正确性。
Abstract:
Russian original SGDT cementing quality interpretation method is only suitable to singlecasing cement filling evaluation but can not be used to interprete doublecasing cementing logging data. According to doublecasing well that down into Φ 1397 mm casing within the Φ2445 mm casing and statistical analysis of 62 wells’ actual SGDT log data in double casing, the multivariate nonlinear regression method is used to study relationship between inner cement density, outer cement density, well fluids and SGDT log responses, from which the new interpretation model is obtained for calculating the cement density of the inner casing. The processed actual log data verifies that the new interpretation model is correct.
