- 摘要:
- 为了减少原油生产损失，缩短输油管线盗油卡子摘除时间，降低干部职工劳动强度，有必要弄清在摘除盗油卡子过程中存在的问题，识别影响摘卡耗时长的原因。在摘除管线盗油卡子前，存在停井或者停外输泵和放空泄压等准备过程。由于输油管线纵横交错数千米，停井和放空泄压耗时长、工作量大，严重影响采油生产。为此研制了管线带压摘卡专用工具，以解决摘除盗油卡子影响原油生产的问题。专用工具利用了螺旋副原理，用变回转运动实现直线运动，同时传递能量或力。现场应用结果表明，该装置能够实现带压摘卡并且耗时短。其显著特点是：摘除盗油卡子时不需要停井或者停外输，原油生产损失大大减少，劳动强度大大下降。
In order to reduce crude oil production losses， shorten removal time for oil-robbing clamps in oil pipelines and weaken personal labor intensity， it is necessary to find out problems existing in the process of oil-robbing clamp removal and identify reasons for extending oil-robbing clamp removal time. Before clamp removal， it is needed to shut up oil wells and export pumps and oil pipelines are needed to be vented and decompressed， which will consume very long time because pipelines are arranged in a crisscross pattern and thousands of meters long. Furthermore， work load and personal labor intensity are very heavy and also oil production will seriously be affected accordingly. Developed are tools specially used for oil-robbing clamp removal in oil pipelines under pressure in order to resolve such problems which will seriously affect crude oil production. Screw conveyor principle is adopted for manufacturing these special-purpose tools， making rotational motion become straight line motion to transfer energy or force. Field application results show that oil-robbing clamps can be removed from oil pipelines under pressure by using these special-purpose tools and very long time will not be consumed. In addition， such tools have such outstanding feature：it is not needed to shut up oil wells and export pumps during oil-robbing clamp removal from oil pipelines under pressure， crude oil production losses are reduced enormously and personal labor intensity is weaken greatly.
