超短波含水率仪测井效果分析

Logging Effect of the Utrashort Wave Watercutmeter

含水率是产液剖面测井的一个重要参数。在高含水生产井中 ,超短波含水率仪的测井效果明显好于电容法含水率仪。但是在高含水低排量的抽油机生产井中 ,因滑脱效应和仪器探测范围的影响 ,超短波含水率仪也难以取得满意的测井效果。为此 ,河南油田测井公司进行了过环空集流产液剖面测井的研究和试验。试验结果表明 :在高含水低排量的抽油机生产井中 ,集流测井使超短波含水率仪测井效果得到了显著的改善。

Water cut is a key parameter in fluid producing profile logging. In high water content producing well, application effect of ultra short wave watercutmeter is much better than that of capacitance watercutmeter. In addition, in high water content and low flow producing well with pumping unit, good result can not be obtained by using this kind of tool because it is influenced by slippage effect and investigation range. Therefore, in well logging company, Henan oilfield, technicians have done a lot of tests and researches about packer ultrashort wave watercutmeter logging. The result shows that by means of the packer logging, the log effect of ultrashort wave watercutmeter has been quite improved in high water content and low flow producing well.
