油田污水回注中环境控制技术综述

油田产出污水是在油气钻井、开采、处理过程中必然的伴生物，也是石油工业中对环境造成危害的一大污染源。本文从综合治理、合理利用油田污水的角度出发，探讨了对油田污水应用环境控制技术，以治标和治本相结合，从石油工程的工艺本身和改进工艺过程减少油田污水的产出量和提高油田污水的回注利用率，从而显著改进环境质量，充分利用水资源的可能性，也讨论了当前在油田污水治理和回注利用方面应加强研究的几个问题。

A Summary of Environment Control Technique in the Reinjection of Sewage in the Oil Fields

ily sewage is a by-product during drilling,recovery and treatment process. It is a major source causing environment pollution in petroleum industry. From the point of view of comprehensively treating and utilizing the sewage, the paper presents some techniques which combine' radical measures with expedient measures for controlling environment pollution. Technologies of petroleum engineering were improved to reduce the volume of sewage and raise the reinjection ratio of sewage. The paper also points out that the research of treating and using sewage should be stressed.The environment is obviously improved sad the sewage is fully used.
