| 摘 要： | 套管在井下发生脱扣失效事故之后通常要采用测井方法确定失效位置和失效形式。经过对多口井CBL、VDL和CCL套管测井结果进行了调查研究和分析,发现API接箍式偏梯形螺纹接头套管、接箍式特殊螺纹接头套管和直连型特殊螺纹接头套管接头部位在测井图像中均有不同各自的特征,不正常的CCL和CBL曲线和VDL波形位置表明了套管损坏位置和损坏形式。根据CCL、CBL和VDL波形测井结果,可以判断套管接头从现场端脱扣或工厂端脱扣。

| Abstract: | After casing trip happens downhole,well logging methods are usually used to determine the failure position and pattern.Through investigation and analysis to several wells with CBL,VDL and CCL,it is found that there are different characteristics in well logging images for the joint parts of API casing with buttress thread coupling,casing with special thread coupling and connecting casing with special thread.Abnormal CCL and CBL curves and VDL waveforms indicate casing failure position and damage pattern.Casi... |
