摘　　要：双管采油举升工艺技术通过独立的采出液流出通道,降低杆液粘滞阻力,实现常规稠油的有效举升,但在系统理论模型及配套优化手段上的欠缺是制约该技术进一步推广的关键瓶颈。利用室内流变性试验和人工神经网络理论,建立了流动环境下的油水混合溶液流变性模型;同时利用幂律流体流动力学及常规举升工艺作用过程动力学模型,推导了双管系统下的压力场、温度场、流体流动场的动力学模型;结合双管系统工作原理的系统研究,利用节点分析理论建立了双管采油系统工作过程中各模型间的耦合动力学数学模型,并推导了其数值解,最终研发了双管举升工艺参数优化设计软件。现场应用表明:建立的系统理论及优化设计手段计算误差<5%,可有效促进该工艺技术在油田的进一步推广。Dual pipe lifting technology can reduce the resistance between rod and liquid by using the independent liquid flow channel, and can lift heavy oil efficiently. However, the shortness ofthe system theory model and optimization methods restricts the wide use of this technology. Thus,this paper built the oil-water mixture solution rheological model by conducting indoor rhe- ology experiment and using artificial neural network theory. It also inferred the dynamical model of pressure field, temperature field and fluid flow field by using power law fluid flow mechanics and dynamical model in the conventional lifting methods. Furthermore, it built coupling dynamic mathematical model between different models during the work process of the dual pipe lifting sys- tem by using node analysis theory combining principle of this system. Arithmetic solution of the coupling dynamic mathematical model was inferred and dual pipe lifting process parameter optimi- zation design software was developed. Field application shows that the systems theories and opti- mization design methods built in this paper had calculation error within 5%, which can promote the wider use of this technology in oil field.
