Oilfield drilling produces a large amount of oily sewage. If oily sewage is directly discharged without treatment, it will not only cause pollution of soil and water sources, but sometimes even cause slop oil fire accidents, threatening people's lives, causing national economic losses, and harming the interests of the oilfield itself. Therefore, efficient and economical oilfield oily wastewater treatment and reuse technology can achieve the purpose of energy saving, consumption reduction, environmental protection, and reuse of water resources.

SP Solution:

The current treatment technology of oilfield sewage is mainly to achieve the purpose of reinjecting the sewage, removing oil, organic matter (COD), suspended solids, sulfides, bacteria, etc. in the sewage. The oilfield sewage can be reinjected, reused, or Meet the outside row. The main purpose of oilfield reinjection sewage treatment is to remove oil and suspended solids. Generally speaking, sewage treatment can be divided into two stages. The first stage is the degreasing stage. This stage is to use oil, water density difference and demulsification flocculant to remove oil and water. The second stage is the filtering stage. At this stage, the suspended solids, oil and other impurities in the wastewater are adsorbed on the surface of the filter material, or the adsorption and blockage of the filter material are used to prevent it from passing through the filter material layer. The main technical methods used in the deoiling stage include gravity trap technology, pressure sedimentation deoiling technology, hydrocyclone deoiling technology and membrane separation technology.

SP Advantages:

ØThe oil-water separation effect is good, and the separation is thorough.

ØIt can effectively reduce the content of COD and reach the standard of re-injection and reuse.

ØAdvanced technology, strong adaptability, can filter many kinds of impurities at the same time.
