HJ 1248-2022Self-monitoring technology guidelines for pollution sources - Onshore oil and gas exploitation and production industry (English PDF)

1 Scope of application

This standard specifies the general requirements for self-monitoring, monitoring plan formulation, information recording and the basic content and requirements of the report.

This standard is applicable to the water and gas pollutants discharged by the onshore oil and natural gas mining industrial pollutant discharge units during the production and operation stages, and the noise and and carry out self-monitoring of the impact on the surrounding environmental quality. Oil sands, oil shale, shale gas, coalbed methane, natural gas hydrate and other unconventional oil and gas development the self-monitoring of industrial sewage discharge units can be implemented by reference.

Self-monitoring requirements for self-provided thermal power generating units (factories) and supporting power boilers shall be implemented in accordance with HJ 820.

3 Terms and Definitions

The terms and definitions defined in GB 39728 and the following apply to this standard.

onshore oil and gas exploitation and production Oil and gas extraction activities in onshore oil and gas fields, onshore and offshore oil and gas fields and onshore terminals of offshore oil and gas fields, including oil and gas exploration Exploration, drilling, completion, logging,, downhole operations, oil and gas testing, oil and gas production, oil and gas gathering and transportation, and oil and gas processing operations or processes it does not include oil sands, oil shale, shale gas, coalbed methane, natural gas hydrate and other unconventional oil and gas exploration activities.

direct discharge

The act of discharging water pollutants directly into environmental water bodies.

indirect discharge

The act of discharging water pollutants to a centralized sewage treatment facility by a sewage discharge unit.

rainwater outlet

A discharge outlet that specifically discharges natural precipitation to outside the factory boundary directly or through ditch, canal or pipeline and other facilities.

volatile organic compounds (VOCs) Organic compounds participating in atmospheric photochemical reactions, or organic compounds determined according to relevant regulations. This standard uses non-methane total hydrocarbons as a monitoring indicator of volatile organic compound emissions from exhaust stacks and enterprise boundaries.

leak detection value Using the specified monitoring method, the VOCs concentration detected by the detection instrument at the leakage point of the equipment and pipeline components is deducted from the environmental background value.

Net value, expressed as mole fraction of carbon.

steam injection boiler used in viscous oil production it is a production equipment that provides high temperature and high pressure steam for the exploitation of heavy oil and super heavy oil.

Oil and gas field heater used in petroleum industry Thermal equipment for heating medium such as crude oil, natural gas, water and their mixtures in the process of onshore oil and gas exploitation, the main types Including tubular heating furnace, water jacket heating furnace, vacuum phase change heating furnace, heat medium heating furnace, etc.

4 General requirements for self-monitoring

The pollutant discharging unit should find out the pollution source, pollutant index and potential environmental impact of the unit, formulate a monitoring plan, set up and maintain monitoring facilities, carry out self-monitoring in accordance with the monitoring plan, do a good job in quality assurance and quality control, record and save monitoring information, and disclose it to the public in accordance with the law Monitoring results.

5 Development of monitoring plan

6 Information recording and reporting

7 Others

The pollutant discharge unit should truthfully record the working conditions during the manual monitoring period (including production load, operation of pollution control facilities, etc.) to ensure monitoring.

Data are representative. The marking of working conditions during automatic monitoring shall be carried out in accordance with the national standard specifications and the marking rules of working conditions of relevant industries.

Content not specified in this standard shall be implemented in accordance with HJ 819.
