Auto Well Control

Technical Characteristics

The Auto well control system integrates equipment operation status monitoring module, well control influx monitoring and early warning module, and automatic control module, realizing intelligent data analysis and monitoring and full automation of multi-equipment linkage, and achieving convenient, intuitive and efficient influx control.

Main monitoring well control equipment running condition monitoring equipment real-time operation data and equipment state, such as the bop state, ram location, the inner cavity drill pipe status, state of choke valve, etc., to realize central control system fully perceive the real-time data of well control equipment, timely warning equipment malfunction, well control automation action do well prepared for the next step. The wellhead influx monitoring and early warning module mainly realizes the monitoring of wellhead influx state in the process of drilling, timely detection of overflow and early warning, reliable judgment basis for closing, early detection of influx and prevention of malignant influx accidents. The automatic control module mainly realizes the full automatic closing. Once the influx is identified, the system will control the rig, well control and associated equipment to realize the well control programmed safe shut-in of oil and gas Wells.

Technological Superiority

The Auto well control system integrates fully automated control program actions into the rig control system. The two systems continuously exchange real-time data and control linkage, and the fully automated overflow control program perfectly runs in the traditional rig control equipment. Once the kick overflow is identified, the system takes control of the rig and associated equipment, automates well control procedures, and safely shuts down the well. The system monitors rig data in real time and makes sound control decisions, replacing the decisions that the driller must make on a manual rig to restore the overflow to a safe state through a series of operations once it is detected. Compared with the traditional well control system control method, the automatic control efficiency of digital well control system is 5 times that of manual control, and can reduce the error rate of manual operation by more than 90%, which significantly improves the drilling safety factor and is of great significance to the well control security of drilling.

The The Auto well control system is a bespoke technology that automates the well shut-in sequence providing automated secondary well control. The technology almost eliminates the human factors in well control events therefore minimizing the influx size and preventing blowouts.
