江汉盆地裸眼井测井遇卡原因分析及应对措施

Cause analysis and strategies of tool sticking in open hole logging in Jianghan Basin

根据江汉盆地的地质构造特点,对近5年来的测井遇卡情况及解决方案进行调查分析。在研究以往遇卡原因及处理措施基础上,按工程表现将将遇卡分为8类,其原因概括为地质、钻井液、工程及测井因素等4个方面,进而有针对性地形成目前江汉地区遇卡问题的解决方案及预防措施,可供现场快速识别遇卡异常现象及其安全高效处理。

According to the geological structure characteristics of Jianghan Basin,this paper investigated the stuck logging tools as well as the solutions in recent 5 years.On the basis of studying the causes and the solutions of past tool sticking and in terms of the engineering performance,the tool sticking is classified into 8 categories.The causes are summarized as geology,drilling fluid,engineering and logging,so as to provide the solution to the problem of the tool sticking aiming at Jianghan area and the relevant preventive actions,which can be used for their quick identification and safe and efficient handling.
