Effective Approach to Improving Drilling Rate According to the Analysis on Drilling Rate Equation

Abstract:

Under safety condition, improving drilling rate is the goal and urgent task for the drilling engineers and technicians．According to Daqing Changyuan general drilling rate equation, the analysis was made on main factors affecting drilling rate and effective approach to improving drilling rate, which was helpful for drilling engineering design. Actual drilling data of well Yingshen 1 and Dashen 2 were verified by general drilling rate equation with the fault only 4.3% and 4.8% between the predict and actual drilling rate, good coincidence rate was acquired.
