Yaoyingtaioilfield On Anticorrosive And Acale Technology Research

Shorter exemption period Yaoyingtai oilfield wells， oil wells serious corrosion andscaling to a large extent affected the normal production of oil wells. Therefore， through thisproject， to carry out the laboratory test of corrosion and scaling analysis of the main factorsthat affect Yaoyingtai oilfield corrosion and scaling， which is the preferred anti-corrosionScale matching technology to solve the problems of corrosion and scaling basis to improveproduction wells exemption period.This thesis Yaoyingtai oilfield mining wells corrosion， scaling and other issues， thefull analysis of the injection of produced water， corrosion and scaling analysis of differentblocks from the point of view of water quality; using X-ray diffraction （XRD） and X-rayfluorescence spectrometry（XRF）analysis，the scale sample of the mineral composition andchemical elements by corrosion products and scale sample composition speculated that thereason for corrosion and scaling; predict corrosion rate corrosion and scaling experiments toevaluate the on-site use of corrosion inhibitors; throughclear sewage mixed test to identifyQing sewage best mixed ratio; determination of water samples for the presence of corrosivebacteria by bacteriological analysis， analysis of water samples in the presence of bacterialcorrosion; final analysis of the test data， combined with theoretical analysis，comprehensiveresearch analysis impact the Oil Well Yaoyingtai corrosion and scaling themain reason.Through research: and corrosion for speed the oilfield water static state， for high-speedcorrosion current state. The main factors affecting corrosion: chloride， salinity， bacteria，and scaling. Fouling serious main reasons: the high content of bicarbonate ions， mainlycarbonate scale.In order to extend the the pump inspection cycle， combined Yaoyingtai oilfieldanticorrosive Scale the work done over the years， some exploration and research pipelines，oil wells， anti-corrosion， scale inhibitor process in2012. I plant， pipelines， oil wellscorrosion factors of sustained-release scale inhibitor screening wells dosing and dosingamount of change， and watered dosing to reduce a watered corrosion rate.
