查询词典 clay

On the basis of the laboratory data and by widely analysing the formation origin and mechanism of low-resistivity oil/gas reservoir, a point of view is put forward which is not consistent with the idea existing for a long time, that is not all the low-resistivity oil/gas reservoir is shaly sandstone. Fine grains or pure fine siltstone can also form the low-resistivity oil/gas reservoir. And the additional conductibility of clay will become the prominent factor that causes the low-resistivity only when the salinity of formation water is lower. Actual cases indicate that when the salinity of formation water is greater than 300000ppm or so, even ifthere is some clay, its additional conductibility can also be ignored.

建立在实验室数据的基础之上，并通过广泛地低电阻率油气储集层成因和机理分析，提出了与长期以来存在于人们头脑中的思想观念不相一致的看法，即认为低电阻率油气储集层并非都是泥质砂岩，岩石颗粒细小的或纯净的细粉砂岩也可能形成低电阻率油气储集层，并且粘土的附加导电性也只有在地层水矿化度比较低时，才会成为造成低电阻率的突出因素，事实表明，当地层水矿化度高于大约300000ppm时，即使储集层含有一些粘土矿物，它所产生的附加导电性也是可以忽略的。
