| 摘 要： | 钻井过程中出现泥浆滤液侵入储集层而出现的低电阻率环带是储集层含有可动油的有力证据.高频等参数感应仪器(VIKIZ)具有良好的探测低电阻率环带的特性.对泥浆侵入现象进行了描述,进一步论述了低电阻率环带形成的机理,通过对高频等参数感应探测特性的分析,并通过测井实例,阐述了高频等参数感应在利用低电阻率环带评价油气层方面的独特优势.

| Abstract: | During drilling,the mud filtrate may invade reservoirs,in some cases it causes low resistivity annular zone(annulus).The formation of annulus is an evidence that the reservoir bears movable oil.VIKIZ has the ability to detect the annulus.This paper first describes the phenomenon of mud invasion,and further discusses annulus formation mechanism.Based on the analysis of VIKIZ detection characteristics,the paper analyzes VIKIZ's unique property in comparison with the traditional induction logging instrument.Lo... |
