Guidelines for Safety Assessment in onshore oil and gas Extraction

1. Subject content and scope of application

These Guidelines are formulated in accordance with the General Principles of Safety Evaluation, and stipulate the purposes, basic principles, contents, procedures and methods of safety pre-evaluation, safety acceptance evaluation and comprehensive safety status evaluation of onshore oil and gas mining industry (hereinafter referred to as onshore oil and gas mining safety evaluation), and are applicable to the safety evaluation of onshore oil and gas mining industry.

2. Purpose and basic principles of safety assessment

The purpose of the onshore oil and gas exploitation safety evaluation is to implement the "safety first, prevention first" policy, improve the intrinsic safety degree and safety management level of onshore oil and gas exploitation, reduce and control the dangerous and harmful factors in onshore oil and gas exploitation, reduce the safety risks of onshore oil and gas exploitation, prevent accidents, and protect the property safety of enterprises and the health and life safety of personnel.

The basic principle of safety evaluation for onshore oil and gas exploitation is that safety evaluation institutions with national qualifications should carry out safety evaluation scientifically, fairly, legally and independently.

3. definition

3.1 Onshore oil and gas extraction industry

Onshore oil and gas extraction industry is a general term for all process units of onshore oil and gas extraction, including exploration, drilling, underground operations and oil recovery, gas production and oil and gas gathering and transportation.

3.2 Safety pre-evaluation of onshore oil and gas extraction industry

The safety pre-assessment of onshore oil and gas mining industry is based on the content of "surface engineering construction plan" of oil and gas fields, through qualitative and quantitative analysis, analysis and prediction of the main dangers and harmful factors that may exist in the construction project and their danger and harm degree, and put forward reasonable and feasible safety countermeasures and suggestions to guide the engineering design, construction and operation management.

3.3 Safety acceptance evaluation of onshore oil and gas mining industry

The safety acceptance evaluation of onshore oil and gas mining industry refers to the investigation and analysis of the safety status and management status of facilities, equipment and devices of onshore oil and gas mining construction projects after the completion of oil and gas mining construction projects and the normal operation of trial production, and before the acceptance of safety production facilities, to find out the dangers and harmful factors that exist after the project is put into operation and determine its risk degree. Put forward reasonable and feasible safety countermeasures and suggestions.

3.4 Comprehensive evaluation of the safety status of onshore oil and gas extraction industry

The comprehensive evaluation of the safety status of onshore oil and gas mining industry refers to the qualitative and quantitative analysis of the dangers and harmful factors existing in the production process of onshore oil and gas mining and production through the investigation and analysis of the safety status and management status of its facilities, equipment and devices, the determination of their risk degree, and the objective evaluation of their safety management status. Put forward reasonable and feasible safety countermeasures and suggestions to existing problems, and give guidance to operation management and measures to be taken in case of extraordinary events.

4. Safety evaluation content

The content of safety evaluation of onshore oil and gas exploitation generally includes: risk evaluation of major risks and harmful factors of oil and gas exploitation; Verify and inspect whether the safety equipment and facilities of oil and gas exploitation meet the requirements of safety production laws, regulations and technical standards; To evaluate whether oil and gas exploitation safety management system can ensure oil and gas exploitation safety production; Put forward reasonable and feasible safety countermeasures and suggestions.

5. Safety assessment procedure

The safety evaluation procedure of onshore oil and gas exploitation generally includes: preliminary preparation; Identification and analysis of dangerous and harmful factors; Divide evaluation units; Qualitative and quantitative evaluation; Put forward safety countermeasures and suggestions; Make safety evaluation conclusions; Preparing safety assessment reports; Safety evaluation report review, etc.

5.1 Preliminary Preparations

Clarify the object and scope of evaluation, collect domestic and foreign relevant laws and regulations, technical standards and oil and gas exploitation data related to evaluation objects.

Collect field data and conduct field investigation.

The information required by the construction unit for safety pre-evaluation of onshore oil and gas mining industry is listed in Appendix A for reference.

The safety acceptance evaluation of onshore oil and gas exploitation industry and the comprehensive evaluation of onshore oil and gas exploitation industry safety status need to be provided by the evaluated units for reference list in Appendix B.
