辽河油田欢喜岭采油厂自1985年大规模开采稠油以来,依据稠油物性特点,陆续安装了部分LCJ1250链条抽油机,截止1992年底,共安装链条抽油机85台次。但在日常生产中经常发生因气压低,空压机丢失,零部件损坏或被盗等原因造成链条断、换向器坏、悬重钢丝绳(毛辫)断等事故。仅1991年10月至1992年2月,就相继发生过24口井因气平衡失效或空压机零件被盗、被破坏等原因造成油井停产事故。结果不仅累计少产油278吨,还加大了维修工作量及费用,降低了油井的有效时率,增加了油井正常生产管理的难度。
Since Haili Ridge Oil Production Plant of Liaohe Oilfield has been producing large amounts of heavy oil since 1985, some LCJ1250 chain oil pumping units have been installed one after another according to the physical properties of heavy oil. By the end of 1992, a total of 85 chain pumping units were installed. However, in daily production, frequent accidents such as broken chain, broken commutator rope and hanging rope (hair braid) often occur due to low air pressure, lost air compressor, broken or stolen parts and other causes. From October 1991 to February 1992, there were 24 oil wells in succession due to gas balance failure or air compressor parts stolen, destroyed and other causes of oil well shutdown. The result not only accumulated less oil production 278 tons, but also increased the maintenance workload and costs, reducing the effective time of the well, increasing the difficulty of normal production and management of the well.
