油气田站场水环境治理与绿化设计应用

长庆油气区大部分地处失陷性黄土地区,其区域特性、降雨特点及地面集流方式易产生水土流失、滑坡、泥石流等自然灾害。通过采用道路型雨水收集和分类区别处理技术对站场设计优化,将站场雨水、废水收集回收利用从而减少外排,既减少排水引起的自然灾害和后期维护费用,又可满足站场绿化用水,节约水资源。经过设计应用初步形成了适应于长庆油气区实际的站场水环境治理与绿化设计模式,为后期新建油气田的治理提供新思路和方法。

Design and Application of the Management and Afforestation for Water Environment of Oil and Gasfields

Changqing Oil and Gas Region is mostly located in the fallen loess region,the regional characteristics,rainfall characteristics and ground set flow mode of which are easy to cause soil erosion,landslides,mudslides and other natural disasters.The station design is optimized by road-type rain collection and classified treatment technology.Rain and sewage of the station are collected and recycled,thus decreasing the outward drained amount,as well as the number of natural disasters caused by sewage draining and the maintaining cost,also saving water for the afforestation of the station.The treatment and afforestation model special for the actual station water environment of Changqing Oil and Gas Region is initially formed by design and application,which provides new ideas and methods for the afterward treatment of newly built oil and gasfields.
