undergauge

基本解释

The relationship of drilling fluid density and formation dip with borehole undergauge creep deformation encountered in salt beds in Xinjiang Oilfield drilling was studied.
研究了新疆某油气田钻遇的盐岩层段钻井液密度、地层倾角与井眼蠕变缩径的关系。
For example the gravel top,which is easy to collapse,the abnormal high pressure of Anjihai formation,the undergauge happened in Taxi river and Shawan formation.
如上部极易坍塌的砾石层、安集海异常高压层、塔西河沙湾的缩径,给钻井施工增加了相当大的难度。
