| 摘 要： | 目前蒸汽吞吐井采用的电加热及热流体循环工艺,存在能耗大、运行成本高及井下作业复杂等问题。依据热管原理,将机抽井中的空心抽油杆经过加工处理,改制成具有高效传热功能的重力热管,并形成了利用抽油杆柱吸收地热加热井筒新技术。介绍了油井现场制造重力热管式抽油杆柱的操作工艺,依据辽河油区3口试验井资料,分析了该技术的适用条件及影响因素。结果表明:对于油层深度低于1 300 m、油层流体温度为100～120℃、油层条件下原油黏度小于10 000 mPa.s、周期注汽量不低于2 000 m3及产液量不低于15 m3/d(最好在20 m3/d以上)的蒸汽吞吐井,应用该技术可取得加热井筒的好效果。 |
