油气开采固废污染控制国标7月实施

Core Viewpoint - The Ministry of Ecology and Environment has released the national ecological environment standard for solid waste pollution control in the oil and gas extraction industry, which will be implemented from July 1, focusing on the management of solid waste generated during extraction processes [1] Group 1: Overview of the Standard - The standard outlines overall requirements for pollution control related to solid waste such as water-based cuttings and oil-containing waste generated during onshore oil and gas extraction [1] - It emphasizes the need for effective collection, storage, transfer, utilization, and disposal processes, as well as monitoring of environmental pollutants [1] Group 2: Waste Management and Utilization - The standard categorizes solid waste into different types, including hazardous waste like oil-based cuttings and oil-containing sludge, which require specific management practices [1] - It encourages comprehensive utilization and the implementation of technologies such as drilling mud recovery systems to minimize waste generation and environmental risks [1] Group 3: Pollution Control Requirements - Specific pollution control measures include ensuring that water-based cuttings have a moisture content of less than 60% after solid-liquid separation [2] - The standard outlines five key areas for pollution control during the utilization and disposal of water-based cuttings, including direct use in site preparation and road construction, and requirements for handling polymer and sulfonated cuttings [2] Group 4: Treatment Technologies - The main technologies for managing oil-containing waste include thermal desorption and pyrolysis, with strict pollution control measures required throughout the process [2] - Recovered mineral oil from thermal desorption can be reused in oil-based drilling mud or as fuel oil, provided it meets relevant standards [2]
