Abstract: Restricted by regional conditions, a proposed crude oil pipeline has to pass through Dawu groundwater enrichment area. This paper discusses the technical prevention measures for pipeline passing through groundwater enrichment area from the aspects of pipeline body, anti-corrosion, line block valve chamber, leakage detection, optical fiber early warning, groundwater monitoring well and anti-seepage scheme, and puts forward some environmental protection requirements for construction period and operation management, so as to improve the intrinsic safety of pipeline, reduce the environmental risk of pipeline leakage and ensure the safety of groundwater environment

Key words: crude pipeline, groundwater enrichment area, environmental protection
