摘　　要：针对采油三厂部分油井含蜡量高、黏度高,油井生产困难,维护难度大的问题引进双空心杆内循环热采技术,热载体纯净水加热后从双空心杆内管进入外管返回,达到提高油管内原油温度,防止油管内壁结蜡,降低原油黏度,改变流动性的目的。可利用油井伴热水、套管气、太阳能等多种热源,对双空心杆热载体加热,在密闭的系统实现井筒升温清防蜡及降黏作用,保证油井的正常生产,对类似油井的开采具有借鉴意义。Double hollow pumping rod heating technology was applied by putting heated pure water into inner channel and returning from outer channel,which improved the crude oil tempreture,prevented paraffin deposit,decreased crude oil viscosity and enhanced the flow properties.The pure water was heated by heat tracing wate or casing pipe gas or solar collector etc.This technology can achieve cleanuping paraffin and decreasing crud oil viscosity.It has a good r refrence for similar oil well producing.
