With the development of petroleum industrialization, pollution problems brought about by the drilling process are getting more and more attention. At present, there is not yet a well-established effective treatment process that is suitable for drilling waste liquids in China. This is mainly due to the variety of drilling fluids and working liquid systems, their complex composition and their different usage conditions. The techniques that result in the use of effluent for a particular type of field or area of the field are not necessarily suitable for effluents of other types or areas. In addition, compared with the current comprehensive level of wastewater treatment in the oil industry, the disposal costs of drilling waste liquid and wastewater are high, and the treatment effect is general. In general, the current drilling wastewater treatment technology is far from satisfactory.
Mainly in:
1, the treatment agent performance is not high
- Single treatment method, limited ability to remove pollutants
3, continuous processing device is not targeted, high processing costs
Regardless of the above-mentioned kind of processing technology, it has a certain scope of application. Therefore, the selection of the method must be based on the nature of the waste drilling fluid generated by each oil field and the geographical, climate, and environmental characteristics of each oil field for the most reasonable optimization. At the same time, in order to more effectively manage the problem of drilling wastewater pollution, the author believes that future research work should not only strengthen the source and process control, but also develop and comprehensively utilize new technologies. Specifically there are the following aspects:
- Pursuing Cleaner Production
- Develop low-cost, high-performance environmentally friendly drilling fluids
- Development of new drilling fluid treatment agent and unified technology
4, the development of harmless comprehensive utilization of new technologies
- Strengthen management control and strengthen process supervision
The clean production drilling fluid purification equipment developed by GN Solids control. can effectively reduce the generation of drilling waste, reduce the generation of waste liquid by 30 to 50%, and effectively reduce the cost of harmless treatment. Minimize the generation of pollutants in the environment.
