| 摘 要： | 坪北属特低渗透油田,油井低产低液,动液面低,不适宜套管掺水加药防腐。坪北油管腐蚀穿孔十分严重。油井采出液含氧高、SRB多是油井腐蚀的根本原因,采出液的矿化度和Cl-浓度高,以及结垢和偏磨是引起井筒腐蚀的客观原因。JHGH-1固体缓蚀阻垢剂能有效的解决油井井筒的腐蚀结垢问题。

| Abstract: | Pingbei Oilfield belongs to extra low-permeability oilfield,which results in low-productivity and low-liquid oil wells and low producing fluid level(PFL).So,it is not suitable to prevent corrosion by means of adding water and agent into casings.In Pingbei Oilfield,there is very serious pipeline corrosion and perforation.The fundamental reasons for oil well corrosion are high oxygen-bearing produced liquid and much SRB.The objective reasons for well bore corrosion are high-salinity and high-concentration of ... |
