The deteriorated water quality harms aquatic resources, threatens people's lives and safety, causes economic losses to the country, and also harms the interests of the oil fields themselves. With the continuous advancement of oil and natural gas exploration and development, drilling activities are becoming more and more frequent. The treatment of drilling sewage has become an important issue that needs to be solved urgently. It is necessary to carry out sewage treatment operations on the sewage generated in oil and gas drilling.

[0003] In the treatment of oil and gas well wastewater, pipelines are usually set up to divert the wastewater generated by oil and gas drilling into a sewage treatment plant for sewage treatment. The sewage treatment device occupies a large area as a whole, and it is not suitable to treat sewage directly at the drilling construction site. The existing oil and gas drilling sewage equipment cannot effectively treat the mud and dirt in the sewage on site. The sewage is easily accumulated during pipeline transmission, causing blockage of the pipeline. In addition, the sewage is easy to clog the filter plate during the filtration process. The self-cleaning ability of the equipment is relatively poor, the anti-clogging treatment ability is insufficient, and the sewage treatment capacity is average. Therefore, we propose an oil and gas drilling wastewater treatment device to solve the above problems. Utility Model Content
