Elm Two Unite-Song One Unite Bury Pipeline Antiseptic Layers Of Surplus Analysis And Research Of Ability To Work

This text passes correctly elm two of Daqing oil field is united --One Song unite person who bury oil pipeline scene to live in environment survey and study, is it take a sample test , environmental corrosivity survey , corrosivity measuring of pipeline and assess of soil to excavate, is it cause person who bury pipeline antiseptic layers of invalid main factor to find out , confirm the environmental grade of corrosion of soil according to environmental comprehensive physics and chemistry index of soil, grasp pipeline antiseptic invalid law of layer , study antiseptic layers of resistivity decay law and to influence that negative pole protect, is it suitable for person who bury antiseptic layer of life-span of the pipeline calculate formulae and actual effect criterion model to propose on the basis of this text, illustrate and simply analyse oil field long to fail person who bury antiseptic layer of surplus ability to work of the pipeline, unite for elm two --One Song unite pipeline antiseptic maintenance of layer , is it put forward science rational suggestion to change. Summarize five contents concretly. 1.Collect elm two to unite——First Song unite pipeline antiseptic layer of wearing out , damaged relevant materials and data. 2.Carry on the corrosivity investigation and corrosivity appraisal to the soil passed the location of the pipeline. 3.The ones that compound the corrosion solution keeping the same with scene environmental soil corrosivity and direct against polyurethane foam polyethylene jacket layer wear out and carrying on the laboratory with the damaged situation Simulation experiment. 4.Protect under the normal , antiseptic intact condition of heat preservation surface to the negative pole , decay according to antiseptic layers of resistivity law and to influence that negative pole protect, is it suitable for person who bury antiseptic layer of life-span of the pipeline calculate formulae and invalid criterion model to set up on the basis of this text. 5.Unite elm two --One Song unite pipeline antiseptic maintenance of layer is it put forward science rational suggestion to plan.
