Establishing risk pre-control management system and hidden danger investigation and management system is an indispensable part of HSE system construction, which is of great significance to the safe development of enterprises. Ecuador is sensitive to environmental protection and safety, and the local oil company of Party A has higher requirements for HSE management. With the goal of "zero pollution, zero emission and zero accidents", the two systems are organically combined, hidden dangers are controlled by closed-loop management mode and risks are controlled by front-end management, which enriches the connotation and extension of compliance management into HSE management, effectively ensures the execution of system construction, and creates a new situation of HSE management and control, which is "controlling risks before hidden dangers form and eliminating hidden dangers before accidents occur". Ecuador is located in the northwest of South America and is rich in oil resources. It is a member of the Organization of Petroleum Exporting Countries (OPEC). The operation area is mainly concentrated in the eastern basin of Amazon rainforest, and the pressure of operation safety and environmental protection is great, which is mainly reflected in the following aspects: (1) the government has high requirements for the treatment of wastewater, sewage and polluted garbage; The local oil company of Party A has high requirements for HSE management, especially for its service contractors. The awareness of safety and environmental protection of local employees and residents has been increasing, and more and more attention has been paid to the safety and environmental protection of oil enterprises. At the same time, some external interest organizations are paying more and more attention to the environmental protection trend in the oil region. The lack of local human resources and the relatively frequent turnover of personnel have increased the pressure on risk management and control; The industrial base of the project country is backward, the technical standards are chaotic and lacking, and it is difficult to control major hidden dangers. It can be seen that the construction of "double control" system based on risk control and hidden danger investigation and management does not meet the requirements of the state and superior units, but is an inevitable requirement for smooth operation in Ecuador, training basic HSE management skills internally and shaping a good image externally. Closed-loop management of hidden dangers is based on the implementation of responsibilities, and the spiral PDCA closed-loop management model is used to investigate and manage hidden dangers. Establish a responsibility system. According to the principles of "managing business must manage safety" and "one post with two responsibilities", a three-level responsibility system of "main responsibility, supervision responsibility and leadership responsibility" for safety work is established. Relying on the three-level management of "one large class, one small class and one platform manager", the main responsibility of safety production is firmly decomposed, and the duties of key positions such as large classes and drillers are strengthened. The responsibility system for safety production is implemented from point to point, and the leaders take the lead in demonstrating. Establish a screening system. According to the risk classification standard of common physical hidden dangers in petroleum engineering, six business contents of drilling, workover, cementing, transportation, fire fighting and ground construction are compiled in Spanish, and the hidden dangers are divided into three levels: hazard factors, general hidden dangers and major hidden dangers. Combined with the classification standard of illegal behaviors, a list of common hidden dangers and violations covering drilling and workover operations is established. In the process of investigation, refer to the list of hidden dangers, effectively use expert meetings, HAZOP, FTA and other hidden dangers identification and analysis methods to ensure the intrinsic safety of people, equipment and technology to the maximum extent, and form a long-term safety management mechanism. Thorough governance and continuous improvement. Take the principle of "four decisions" for the hidden dangers found, that is, determine the responsible unit or department, responsible person, rectification measures and completion deadline. Adhere to the principle of "developing strengths, eliminating shortcomings and increasing advantages". After the completion of hidden danger management, the problem-oriented management ledger and files will be established and improved, and special summary or phased summary review will be carried out to continuously improve the performance of system construction. The investigation and management of hidden risks and risk management and control are two systems which are both related and different from the previous management and control. On the one hand, hidden danger management is to eliminate or control out-of-control hazards within an acceptable risk range, while hazards in a system may not develop into hidden dangers if properly managed. On the other hand, although risk pre-control and hidden danger management are important ways to prevent accidents, risk pre-control is ahead of hidden danger management and has a wider control range. Risk database and risk quantitative rating. For key areas and high-risk links such as unit operation risk, project start-stop risk, demolition operation risk, crossover operation risk, environmental pollution risk, etc., implement risk assessment and risk database update application, strengthen risk pre-judgment, introduce risk sensitivity assessment on the basis of possibility and severity, and correctly evaluate the special consequences and impacts caused by hidden accidents in special periods and special regions. Apply risk management tools. Continue to strengthen the application and implementation of seven risk management tools in our unit, such as safety observation and communication, work safety analysis, work cycle analysis (inspection), work permit, personal safety action plan, safety experience sharing and pre-operation safety meeting, so as to control risks within an acceptable range, effectively reduce hidden dangers of accidents and ensure safe production. Continue to strengthen the construction of three standards and one standard on site. Promote the standardization construction on site through visual management, quantitatively locate and mark the required articles and tools, warn the regional danger degree through different color areas, standardize the on-site production through visual perception information, put an end to habitual violations and avoid operational risks; Standardized operation is realized through control means such as operation procedures, work safety analysis and work permit; Standardized management is realized through HSE management process, monthly assessment, daily inspection and key inspection. Compliance management promotes implementation, promotes the construction of "double control" system with compliance management as the combination point, takes compliance management as the platform, takes effective system implementation as the basis, takes training and education as the method, and takes inspector assessment as the starting point, continuously strengthens embedded compliance management to penetrate into the whole HSE process management, and continuously and effectively promotes the construction of "double control" system according to laws and regulations, so as to ensure that the system construction is implemented and achieved practical results. Dynamic organization management. System is the "regulation" of "double control" system, and a perfect system is the cornerstone and guarantee of system construction. At the same time, adhering to the dynamic system management idea of "effective circulation and timely improvement", the Compliance Management Department takes the lead in timely or regularly evaluating the compliance and adaptability of the existing system, and updates the system according to the relevant requirements of the superior system and Ecuador, thus forming a benign interaction between system development and system construction and compliance management requirements. Strengthen training and education. Carry out publicity of rules and regulations, emphasize everyone's participation, constantly promote the formation of new employees' safety habits, prevent old employees from "fatigue" in safety awareness in time, persist in strengthening red line awareness, implementation awareness and bottom line thinking, and let Chinese and foreign employees internalize the requirements of safety development concept into their work. Taking post risk identification, security database analysis and business operation as the training contents, we will carry out multi-level, multi-field, multi-demand and multi-channel training to continuously improve the level of employees in finding hidden dangers and identifying risks, improve business operation skills and team quality, and prevent accidents. Implement evaluation rewards and punishments. Give full play to the guiding and stimulating role of assessment, advocate an active atmosphere of "comparing, learning, catching up and surpassing", and strictly implement quantitative assessment of key positions, units and departments. The construction of "double control" system based on compliance management can realize comprehensive risk assessment and prevention and control in advance, hidden danger investigation and evaluation and process control in the event, and evaluation and improvement after the event, which is an important way and method to improve HSE management level.
