摘要: 本模型是根据Coats1980年发表的火烧油层模型经改进研制的三维、三相、两组份、全隐式注蒸汽开采数值模型。考虑了以下因素:1.轻质馏分的蒸馏作用及流体流动时的携热作用;2.油层的非均质、各向异性、传热性;3.温度、压力对流体性质的影响;4.流体及油层的压缩性;5.毛管力、粘滞力、重力;6.井筒及上、下盖层的热损失等。节点序号按“红一黑”排列,形成2循环系数矩阵,求解变量个数可约简一半,有直接解法、多级循环块松弛迭代法。本模型可用于研究一、二、三维,油、汽、水三相,考虑蒸馏作用的蒸汽驱问题及柱座标单井蒸汽吞吐问题,也可计算注冷/热水驱问题。最后,与1985年SPE考题作了对比。

Abstract: This Simulator is based on Coats's "In-Situ Combustion Model",The conditions considered in the simulator are: distillation of light components,heat conduction and convection,effects of pressure and temperature on the behavior of fluids,compressibility of fluids and reservoir rocks,capillary pressure,gravity,and heat loss in the wellbore and through the overburden strata.There are direct and iterative solution techniques for selection.This simulator can be used to study multi-dimensional,three-phase,two-com-ponent steamflooding and steam huff and puff problems.
