breakout pressure मीनिंग इन हिंदी

Using logging information can make the size and direction of in - situ stress , and then determine fracture pressure and breakout pressure so can provide the suitable mud density to solve the mechanics instability of borehole
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
Based on the variables of inlet length , compression ratio , inlet opening phase and the exhaust closing phase , multi - objective optimization was conducted for power , torque , combustion noise and fuel consumption indicators with constraint conditions of fuel consumption rate and the maximum breakout pressure
Based on the above methodological analyses and practical situation of feixianguan interval in the luojiazhai and dukouhe structure on the east of sichuan , a set of well log interpretation formation pressure application program is developed . it has been successfully applied to the fine interpretation of luojia4 well and du4 well , and so on . the results of formation pore pressure , fracture pressure and breakout pressure are all accordant with the practical situation
