浅析石油钻井泥浆污染特性及其环境保护措施

Pollution characteristics and environmental protection of oil drilling mud

在油井钻进的过程中会产生大量的污染物,其中最具破坏性的是废弃泥浆,原因在于泥浆中金属元素较多,并且各类聚合物的p H值较高。如果未能加以控制,则会对土壤、水体等造成严重污染,因此当前需要明确废弃泥浆的来源及特点,并在此基础上对循环系统加以调整,同时还应对生产工艺及处理技术进行改进,文中对此问题进行了详细探讨。

Pollutants are produced in the process of oil well drilling,of which the waste mud is the most destructive due to the metal elements in the mud,and the high pH value of various kinds of polymers.If it is not controlled,it will cause serious pollution to the soil and water.This paper describes the source and characteristics of the waste mud,based on which the circulation system is adjusted,and the production process and treatment technology are improved as well.
