油气管道穿越黄土沟壑采空区风险性评价分析
Risk Assessment Analysis of Oil and Gas Pipelines Traversing Gob in Loess Gully Region
-
摘要: 黄土沟壑采空区是西气东输油气管道的必经之路,对油气管道穿越黄土沟壑采空区的风险性评价是解决通过采空区管道安全运行的重大问题。在黄土沟壑区开采沉陷衍生灾害研究成果的基础上,结合该积分法来进一步对油气管道穿越采空区进行风险性评价,通过工程实例与现场实测证明,该方法在油气管线穿越黄土沟壑区风险性评价中具有可行性。Abstract: Loess gully region gob is the only ways for West-East oil and gas pipeline, the risk assessment on oil and gas pipeline traversing gob is a major issue for solving operation of pipelines. It combines with integral method to further make risk assessment on oil and gas pipelines traversing god based on the results of mining subsidence hazard study in loess gully region. The method has proved that it has some guidance on risk assessment of oil and gas pipelines traversing the loess gully region.
