摘要： 介绍了全液压稠油热力开采系统的采油装置及其液压技术原理,分析了系统的可行性,对系统进行了井下流体热力学研究.通过建立物理和数学模型以及使用计算机进行仿真,得到当原油的井底温度一定时,液压油在系统中具有与其等效的加热效率,进而得到原油的出井温度与液压油的输入温度及原油保温所需的液压油最小输入温度与液压油的流量基本呈线性关系.验证了该系统对稠油的加热和提采方式是可行的,而且效果比较理想.该模型的建立也为进一步研究井下流体传热情况提供了理论基础.

Abstract: The oil exploiting facility and hydraulic working principle of the fully hydraulic thermal exploiting system for viscous crude oil are introduced with its feasibility analyzed. In the system, the bottom hole fluids are studied thermodynamically by means of developing physical and mathematical models and simulation on computer. It was found that when the bottom hole temperature of crude oil remains unchanged, the heating efficiency of hydraulic oil is equivalent to that of crude oil, and the outlet temperature of crude oil is basically in linear relation to inlet temperature of hydraulic oil. In addition, the hydraulic oil lowest inlet temperature needed for crude oil heat preservation is also basically in linear relation to hydraulic oil flow rate. Thus the way proposed to the system to heat and exalt viscous crude oil is feasible with satisfactory result. The developed models also provide theoretically a basis on which the heat transfer of bottom hole fluids will be studied further.
