气田开发工程水土流失特点与防治对策——以苏里格气田为例

结合苏里格3个气田开发工程的实际情况，对苏里格气田开发工程的组成、征占地面积、水土流失防治措施分别进行分析与评价，并通过经验总结，提出目前生产建设项目水土保持工作中存在的问题和不足。结果表明：1）气田工程项目组成较为复杂，占地以临时占地为主，占整个项目占地的75％左右；2）在水土流失防治分区中，以管网区与道路区所占比例最大，占整个项目占地的90％左右，同时也是整个项目中产生水土流失的重要部位，占整个项目水土流失量的90％左右，是水土流失防治与监测的重点部位。根据调查提出目前水土流失防治措施中存在的问题，并提出建设性意见和具体思路。

Soil and water losses of the natural gas exploitation projects and its control measures: A case study in Sulige natural gas field

Based on three natural gas exploitation projects in Sulige field, this paper analyzed and compared proportions and areas of different land use types, and demonstrated different control measures on soil and water loss. Combined with lots of practice experiences, this paper also discussed the existing problems and obstacles in the current soil and water conservations for natural gas exploitation projects. The results demonstrated that： 1 ） the exploitation of natural gas project occupied many different land use types and on the whole, it can be divided into permanent and temporary land. Temporary land accounted for 75% of the total project area. 2） In the soil and water control areas, the area of pipe network and road was up to 90% of the total project area. Meanwhile, the two land uses contributed to 90% of the total amount of soil and water losses, being the vital areas for monitoring and controlling soil and water erosion. 3） The existing technical problems and obstacles in the current soil and water control measures were pointed out according to investigations and experiences. At the same time, corresponding suggestions were put forward as well.
