Precisely Managed Pressure Drilling System
FST precisely managed pressure drilling system mainly consists of choke manifold control system, back pressure compensation system, remote monitoring system and software system, etc. The system is featured by the integration of pressure monitoring and micro-flow monitoring functions. Through the automatic control software under independent research and development, it enables precise control of bottom hole pressure and achieve delicate managed pressure drilling.
It has various control modes, and adapts to the needs of different drilling technologies;
It meets the needs of drilling technology of low density window, and achieves precise control of well pressure;
It has intelligent identification and automatic control functions, and can optimize the selection of calculation model which combined with well logging data on site;
It has the intelligent error diagnosis and manual intervention reminding, which increases safety and reliability of drilling and production.
It uses proportional control technology and has precise control of system pressure;
It is featured by closed loop monitoring with annulus pressure, multiple strategies, and self-adaption;
The control system uses redundant industrial Ethernet with 100M high-speed data transmission rate;
Without adjusting the drilling fluid density, it can quickly respond to changes in reservoir pressure, protect the reservoir, and reduce the damage;
By reducing drilling pressure, improving drilling speed and reducing number of casing layers, it can reduce drilling costs.
