摘要
Changqing gas field is 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 were treated by a fertilizer treatment agent and were used to improve the desert. So, the soil physical and chemical properties are greatly improved, soil organic matter is increased, capillary porosity increased 3.4 times, powder content increased 12.23 times, clay content increased to 1.62% from zero, cation exchange capacity, organic matter, and soluble nitrogen increased two times. Plant high and weight are also increased by 18.24 and 23.44%, respectively. Soil micro-organisms have a substantial increase by 5-6 times, and conducive to the establishment of soil ecosystem and the formation of a virtuous circle.
