Problems solved by technology

However, since the waste oil-based mud and oily cuttings do not meet the standards for entering the kiln, and the temperature in the incineration kiln is usually around 600°C, this not only cannot completely incinerate the organic matter, but also easily causes skin accumulation in the kiln, and the disposal efficiency and effect are extremely low. Low, due to incomplete incineration, the generated flue gas contains a large amount of organic matter, and the tail gas treatment is not easy to meet the standard; at the same time, because the waste oil-based mud and oily cuttings still retain a lot of heat value, burning directly in the cement kiln will waste energy; incineration produces The detected petroleum hydrocarbon content of the residue is generally above 3%, which cannot meet the requirements of the new landfill standard. If it is directly landfilled without further treatment, it will cause new secondary pollution

Abstract

The invention discloses an oil-based mud and an oil-bearing cuttings recycling system and method. The system comprises a mixing and tempering system, a thermal desorption system and a cement kiln co-processing system, which are simultaneously utilized to recover and process oil-bearing cuttings resources in sequence, thereby recycling waste resources, saving resources and reducing environmental pollution.

Description

technical field [0001] The invention relates to the technical field of resources and the environment, in particular to a resource utilization system and method for oil-based mud and oily rock debris. Background technique [0002] Drilling cuttings refer to the rock fragments that are brought to the ground with the drilling fluid after the underground rock is broken by the drill bit during the oil drilling process. In the process of drilling with oil-based mud, the oil-based mud will bring out a large amount of oil-bearing rock from the well. Cuttings, the waste oil-based mud and oily cuttings produced during the drilling process of oil and gas fields are hazardous wastes mainly containing petroleum hydrocarbons and heavy metal ions such as barium, lead, zinc and their compounds. It will cause great pollution to soil and water resources. With the development of society, the improvement of the legal system and the improvement of environmental protection awareness, it is immin...
