| 中文摘要: |
| 在油田勘探开发施工过程中，根据工程需要添加了许多添加剂，由此产生大量的钻井、完井等作业废液。这类污水组成复杂，不仅含有大量悬浮颗粒和泥沙，而且含有可溶性无机物、有机小分子、高分子化合物、油类及胶体物质，是一种高度稳定的多级分散复合体系，具有一定黏度并且pH值差异大，与地层水混合不配伍。根据环保要求，对钻井、污水进行处理使水质达到回注非储层指标。 |
| 英文摘要: |
| In the oil field exploration and development, according to the project's needs, a lot of additives are added, which generated a lot of drilling, completion and operating waste liquid. Such sewage has complex composition, which not only contains a large amount of suspended particles and sediment, but also contains soluble inorganic materials, small organic molecules, polymers,oils and colloidal substances, and which is a highly stably dispersed composite system. It has a certain viscosity and a large difference in pH, and is not compatible with the formation of water mixed. According to the requirements of environmental protection, drilling, sewage treatment was carried out to make the water reach the reinjection reservoir index. |
