摘要/Abstract

摘要： 蒸汽驱是超稠油开发中最为有效且成熟的方法之一，目前对于蒸汽驱的驱替机理以及技术工艺等研究已相对完善。但对数学模型的研究还不够，对于蒸汽驱动态预测模型的研究还相对滞后。在蒸汽腔演化理论和地层热损率计算研究的基础上，将汽驱过程中的整个油藏分为蒸汽区、过渡区和原油区，运用能量转换和守恒原理，推导蒸汽驱过程中各区域内物理参数表达式，建立汽驱注采模型。同时，针对井网形式和转驱前蒸汽吞吐的影响，推导得到五点井网汽驱动态预测模型。对建立的数学模型进行编程求解，并应用新疆重32井区实际数据进行预测。结果表明：应用该模型可以对蒸汽腔前缘和油水过渡前缘位置进行准确预测，同时可以对产油产水情况进行预测。

Abstract: Steam flooding is one of the most effective and mature methods for the development of super-heavy oil reservoirs.The displacement mechanisms of steam flooding and its technical processes are well understood at present.However, the study of mathematical model and performance prediction model still needs to be further strengthened.Based on the theory of steam chamber growth and the study of subsurface heat loss, the reservoirs in steam flooding process are divided into steam zone, transition zone and crude oil zone.The energy conversion and conservation principles are used to get the expressions of physical parameters in each zone of steam flooding and build injection-production models for steam flooding.At the same time, a performance prediction model is built for five-spot well pattern according to well patterns and the influences of cyclic steam stimulation before steam flooding.The model is solved by programming and the actual data of Zhong32 Block in Xinjiang are used to test it.The results show that the model can accurately predict the locations of fronts of steam chamber and oil-water transition zone.In addition, it also can predict oil and water production.
