埋地原油集输管道防腐技术适用性分析

Applicability Analysis of Anti-corrosion Technology for Buried Crude Oil Gathering and Transportation Pipelines

原油集输管道是油田开发生产的重要组成部分,它们是将原油从油田运输到加工厂的必要途径。不同于其他管道,原油集输管道的管径较小,这是因为原油密度大,流动阻力大,所以需要较高的输送压力,而较小的管径可以提高输送压力。然而,原油集输管道也有一些问题。首先,它们输送的是含水原油,而水是一种强烈的腐蚀介质。其次,管道埋地在土壤中,土壤中的化学成分、微生物和温度等都会影响管道的腐蚀情况。这些因素会导致原油集输管道的使用寿命较短。为了解决这些问题,需要新的防腐蚀技术和方法,以提高原油集输管道防腐技术水平,延长管道使用寿命。

Crude oil gathering and transportation pipelines are an important component of oilfield development and production,and they are a necessary way to transport crude oil from the oilfield to the processing plant.Unlike other pipelines,crude oil gathering and transportation pipelines have a smaller diameter because of the high density and flow resistance of crude oil,which requires a higher delivery pressure.A smaller diameter can increase the delivery pressure.However,there are also some issues with crude oil gathering and transportation pipelines.Firstly,they transport aqueous crude oil,and water is a strong corrosive medium.Secondly,pipelines are buried in soil,and the chemical composition,microorganisms,and temperature in the soil can all affect the corrosion of pipelines.These factors can lead to a shorter service life of crude oil gathering and transportation pipelines.In order to solve these problems,new anti-corrosion technologies and methods are needed to improve the level of anti-corrosion technology for crude oil gathering and transportation pipelines and extend their service life.
