深层稠油在油藏条件下具有一定的流动能力 ,但在井筒中的流动阻力却很大 ,造成生产上的困难。该文针对深层稠油油藏的特点 ,在对稠油粘温关系和深井举升工艺进行研究的基础上 ,结合实验室掺稀油降粘效果研究结果 ,对空心杆泵上和泵下掺稀油举升工艺的可行性进行了研究。设计结果及现场生产分析结果表明 ,空心杆掺稀油是一种适合于深层稠油冷采的举升方式。 Deep heavy oil has a certain flowability under reservoir conditions, but the flow resistance in the wellbore is very large, resulting in production difficulties. According to the characteristics of deep heavy oil reservoirs, based on the research on viscosity-temperature relationship and deep-lift technology of heavy oil, combined with the research results of viscosity-reducing effect of dilute oil in laboratory, The feasibility of thin oil lifting process was studied. The design results and field production analysis show that the hollow rod with dilute oil is a kind of lifting method suitable for deep heavy oil cold mining.
