四十臂井径成像测井在普光气田的应用

文中分析了普光气田套管损坏的主要原因,提出利用多臂井径成像测井对普光气田套管状况进行检测,论述了多臂井径成像测井仪的功能、技术指标、仪器特点、测井资料解释方法,以及该技术在普光气田开发中的应用情况。研究及应用效果表明,多臂井径成像测井技术可以检测井下套管损坏和加速损坏的状况,据此提出了套管防护措施,延长了套管使用寿命,从而增加了普光气田的气井开采年限;对修复井下损坏套管、恢复气井正常生产提供帮助,同时为下步综合治理措施方案提供科学依据。

Application of 40-arm caliper imaging logging in Puguang Gas Field

This paper analyzes the main causes of casing damage in Puguang Gas Field.It is proposed that the technical condition of casing should be monitored using multi-arm caliper imaging logging.It also discusses the function technology index of multi-arm caliper imaging logging instrument,scaling method and instrument features,the interpretation method of logging data and the application situation of this technology in the development of Puguang Gas Field.Aiming at the study and application results,the environment of borehole casing damage and produced and accelerated damage is predicted.The casing protection and remedy measures are taken,prolonging the useful life of casing.The production time of gas well can be extended.The necessity of guiding the workover treatments using the multi-arm caliper imaging logging data is further proved,which can provide help for repairing the casing and putting back on production of gas well,and also can provide the scientific basis for the next step comprehensive treatments.
