Drilling and well control refers to controlling and managing water injection wells and oil and gas wells during the exploration and development of oil and gas wells. The safety management of drilling well control is the most important in the safety work of oil and gas exploration and development enterprises. When working underground, the safety management of drilling and well control is, to some extent, the weakest link in the entire oil industry chain.
Analysis of the status quo of drilling and well control safety management
The increased intensity of oil and gas exploration and development brings increased risk. If a safety accident occurs in the process, it will affect the normal exploitation of oil and cause serious economic losses. Well control safety management is essential. Drilling and well control safety management, at present, more attention is paid to the treatment after the accident, but not to the prevention work.
In fact, before oil extraction, if the production safety assessment is not in place, there will always be hidden dangers in the process of oil extraction. Suppose the publicity of drilling and well control safety management work is not in place. In that case, the person in charge pays too much attention to economic interests and neglects necessary publicity work, which will also result in the relatively low safety quality of employees in oil exploration, resulting in the possibility of man-made accidents. It will lead to heavy casualties and economic losses.
Working methods of drilling and well control safety management
Raise awareness of drilling and well control safety management
We should raise the awareness of drilling and well control safety management, guide the operation team to understand well control, understand well control, study well control, completely eliminate the thought of inattentiveness, and ensure that everyone participates in well control work.
Strengthen the standardized management of drilling well control equipment
The installation and use of drilling well control equipment should meet the requirements of safety management work through standardized management. From the design source, on-site installation, start-up acceptance, safety inspection, and other links, it must comply with the use standards and specifications for the installation of well control equipment. High standards for design, high standards for on-site installation, and strict requirements for start-up acceptance and safety inspection.
Improve emergency response capabilities
Strengthen the ability of emergency response to accidents, improve various plans, do drilling and well control drills, and revise and improve emergency plans for accidents. Regular well control meetings and well control inspections are carried out on a regular basis to improve on-site emergency handling procedures and emergency plans gradually. It is necessary to actively take effective measures, carry out training on employees’ risk identification and risk response through various methods, and make full use of accident case analysis to improve the safety quality and accident prevention ability of all employees.
It is necessary to ensure that the well control equipment is intact and reliable, the monitoring and measurement are accurate, the well control risk is researched and judged in a timely manner, the emergency preparation is fully in place, and the emergency response guarantee is strong.
Well control certification is an essential system of well control management. It is also the basic work that must be done and done well and an effective measure to ensure well control safety.
Strengthen safety inspection efforts
The safety inspection is an important measure to realize the safety management of drilling well control. Before drilling operations, all departments must carefully check the implementation of various safety measures within the scope of operations and confirm them.
The drilling and well control simulation system and emergency exercise simulator, etc., can also effectively help the staff strengthen the ability of emergency response operations and emergency handling. Through the simulation system, drilling staff can be trained in emergency response and rescue.
