borehole collapse造句

• Analysis of borehole collapse cycling time for shale
  泥页岩井壁坍塌周期分析
• This thesis integrates the borehole collapse model with the artificial fracture and imaging well logging to get the size and direction of in - situ stress , and set up the reasonable prediction model of fracture pressure and breakout pressure for carbonate profile , by making use of the rock mechanics parameters from logging information , based on comparing the present various prediction models
  本文在此综合应用井眼崩落法、人工压裂法和成像测井法以确定地应力的大小和方向，并在分析比较国内外各种地层破裂压力和坍塌压力预测模型优缺点的基础之上，从测井资料中提取多种岩石力学参数，建立了适合于碳酸盐岩地层的破裂压力和坍塌压力预测模型。
