Pressure controlled drilling can effectively control the ambient downhole pressure and avoid reduction or loss of drilling performance caused by formation fluid invasion. It can provide dynamic monitoring of the back pressure, fluid density, fluid rheological behavior, annulus liquid level, circulating friction and the geometric dimensions of the wellbore and automatically implement corresponding countermeasures in regards to the conditions monitored. As such, it can achieve the timely, efficient and cost effective treatment of failures. Comparative monitoring of pore pressure and fracture pressure is maintained for the forecasting of any possible well flow, collapse, leakage or other incidents and to facilitate the determination of preventative measures.
The company can render first-class technical pressure controlled drilling services for clients to help reduce the risks and amount of investment required for deep well drilling projects.
