Changqing gas field located in semi-desert or semi-desert grassland,arid climate.Waste drilling fluid was produced as a result of gas field development contained high moisture,organic and clay.So waste drilling fluid could be used to improve the desert.Waste drilling fluids was treated by fertilizer treatment agent and was used to improve the desert.So the soil physical and chemical properties was greatly improved,soil organic matter was increased,plant high and weight was also increased,soil microorganisms had a substantial increase,and conducived to the establishment of soil ecosystem and the formation of a virtuous circle.
