| Abstract: | A Simulated test was made to indicate the charges in volume and in Pressure of ths lubrication system in a roller cone bit at high temperature and under high pressure downhole.The test results and the analysis on the working condition of downhole bit show an expansion of around 2%~3% in volume of the lubrication system caused by high temperature and dynamic load on the bit drilling.The pressure difference between the inside and the outside of the system is about 0.3~0.5MPa. |
