Guidelines for Safety Assessment in onshore oil and gas Extraction

5.2 Identification and analysis of dangerous and harmful factors

According to the process of oil and gas exploitation and the characteristics of local natural environment and surrounding environment, the dangerous and harmful factors in the production process are identified and analyzed.

5.3 Divide evaluation units

On the basis of identification and analysis of dangerous and harmful factors, according to the needs of evaluation, the evaluation objects are divided into evaluation units according to the function of oil and gas production process, the relative spatial location of production facilities and equipment, the category of dangerous and harmful factors and the scope of accidents, so that the evaluation units are relatively independent and have obvious characteristic boundaries.

5.4 Qualitative and quantitative evaluation

Scientific, reasonable and applicable qualitative and quantitative evaluation methods are selected to make qualitative and quantitative evaluation of the dangerous and harmful factors that may lead to major oil and gas mining accidents, determine the cause factors, influencing factors and accident severity, and provide a scientific basis for the development of safety countermeasures.

5.5 Put forward security countermeasures and suggestions

1) Safety technical countermeasures

2) Security management measures

5.6 Safety evaluation conclusion

On the basis of the analysis, induction and synthesis of the evaluation results, the safety evaluation conclusion is made.

1) Summarize and synthesize the evaluation results of each part

2) Conclusion of overall evaluation of oil and gas exploitation safety

5.7 Preparing safety assessment reports

The safety evaluation report of onshore oil and gas exploitation industry is a summary of the process and results of the oil and gas exploitation safety evaluation. It should include the general situation of the evaluation object, the safety evaluation process, the safety evaluation method adopted, the safety evaluation results obtained, and the safety countermeasures and suggestions.

5.7 Review of safety evaluation report

The evaluated unit shall send the safety evaluation report to the expert review group for technical review according to the regulations, and the expert review group shall put forward written review opinions. The evaluation agency shall revise and improve the safety evaluation report according to the opinions of the expert review group.

6. Content and requirements of safety evaluation report

6.1 Contents of the safety evaluation report

1) Basic information of the evaluation object

2) Basis for safety evaluation

3) Identification and analysis of oil and gas development process and main dangers and harmful factors

4) Division of evaluation units and selection of evaluation methods

5) Qualitative and quantitative evaluation

6) Safety countermeasures and suggestions

7) Evaluation conclusion

6.2 Requirements for safety assessment report

Safety evaluation report should be comprehensive, clear, complete data, accurate conclusions, put forward concrete and feasible countermeasures, evaluation conclusions objective and fair.

Seven. Safety evaluation report format

Safety assessment reports generally include:

1) Cover (see Appendix C for format)

2) Photocopy of the safety evaluation qualification certificate of the evaluation agency

3) Description items (see Appendix D for format)

4) Catalog

5) Prepare notes

6) Preface

7) Text

8) Accessories

9) Appendix

8. Safety evaluation report carrier

The safety evaluation report is generally carried by paper carrier. In order to meet the needs of information processing, the safety assessment report can be assisted in the form of electronic carrier.
