摘要
针对普光气田套管变形井的测井难点,介绍了40臂井径成像测井仪的功能、技术指标、刻度方法及仪器特点,研究了测井资料解释方法,根据普光气田的特点建立了资料解释标准。应用该技术对普光气田24口气井套管进行检测,发现套管变形的井有22口,占总井数的91.7%,对套管变形段岩性分析发现均为纯盐岩。
The paper introduces the function,technical index,calibration and characteristics of 40-arm Caliper Imaging logging tool.Meanwhile,it studies the logging interpretation.Based on the data in Puguang gasfield,the interpretation standard is confirmed.The image logging has been applied to testing the casing for 24 gas wells.It is found that there are 22 wells with deformed casing,accounting for 91.7%.And the analysis shows all intervals with deformed casing are composed of pure salt rock.
