Investigation Of Oil And Gas Pipeline Route Protection Technology In Changqing Oil Field

Changqing Oilfield located in Shaanxi,Gansu,Ningxia,Mongolia,Shanxi five province,belongs to the typical arid area of the Loess Plateau region,arid climate and fragile ecological environment,at the same time,the distribution of a large number of oil and precious drinking water source protection areas,nature reserves and river environment sensitive area.A large number of oil and gas pipelines,pipelines and other oil and gas pipelines,which are sensitive to the environment,seriously affect the regional environment,water security.If the pipeline safety protection measures in place,affected by the weather,geological disasters,man-made damage and other factors,once damaged pipeline leakage,oil spill caused by water pollution and affect the surrounding environment,will bring immeasurable economic loss and negative effect for the enterprise.Through the study on the loess area of Changqing Oilfield meteorology,topography,hydrology and other natural conditions,determine the research on safety protection of oil and gas pipeline in the direction of.Liang Mao gully loess area,vertical and horizontal distribution of Changqing Oilfield,determine the safe,reasonable and economical routing is the primary work of pipeline engineering safety.According to the geological and geomorphic features,the basic technical requirements of the route alignment are determined according to local conditions.The hydraulic protection of long distance pipeline in loess area is a kind of measure to control the water and soil loss,which mainly includes three kinds of support,protection and slope protection.With the slope pipeline laying,brook road,crossing the slope land in gully head wear,laying different laying type hydraulic protection measures of optimization and choice of economic,security,and according to the typical hydraulic protection measures,determine their application and technical requirements,has the guiding significance for the design of water the hydraulic protection of pipeline.The pipeline in loess area has the risk of landslide,collapse and other disasters through geological hazards,and the corresponding prevention and treatment measures should be determined to ensure the safety of pipeline laying.
