摘要/Abstract

摘要： 针对注多元热流体（蒸汽、热水、氮气和二氧化碳的高温混合物）热采组分多、增油机理复杂、吞吐后转驱规律不同于常规注蒸汽的问题，开展了注多元热流体吞吐转驱替三维物模及数值试验研究。研究以相似准则为基础，根据渤海N稠油油田地质油藏特征为原型，首先建立了三维比例物理模型，开展了水平井注多元热流体多轮吞吐后转驱替的三维物理模拟实验，得到了转驱生产动态与加热腔扩展的对应规律。然后，建立了数值试验模型，在对三维实验数据进行历史拟合的基础上，进行了注多元热流体吞吐后转多元热流体驱、转蒸汽驱、转蒸汽复合氮气二氧化碳驱等注入不同介质的数值试验，对比分析得到了不同生产阶段的主要增油机理。最后，对渤海N油田南区水平井多元热流体三轮吞吐后转驱的工艺参数进行了优化，得到了最佳工艺参数组合。研究结果可为稠油油田吞吐转驱方案设计提供指导和借鉴。

Abstract: Aiming at the problems of injection multi-thermal fluids (the mixture of the high temperature of steam, hot water, nitrogen and carbon dioxide), such as more components, more complex mechanism, different from conventional steam injection etc., a 3-D physical simulation experiment and numerical test on multi-thermal fluids flooding after huff and puff is carried out. Based on similarity criterion and taking a typical block of heavy oil in bohai oilfield as the prototype, a scaled three-dimensional physical model is established firstly. And the corresponding law between multi-thermal fluids flooding production performance and the stage of heated chamber extending is researched by three-dimensional physical simulation experiment of multi-thermal fluids flooding after huff and puff by horizontal wells. Then, the numerical simulation software stars module was used to establish the numerical model, on the basis of history matching of physical model, three numerical tests of multi-thermal fluids flooding, steam flooding and steam compound nitrogen to carbon dioxide flooding are carried out, and the temperature field and production performance are contrast analyzed. Finally, the best injection production parameters of N heavy Oilfield are optimized by numerical tests. The results can provide guidance and reference for the multi-thermal fluids flooding plan design of heavy oilfield.

Key words: horizontal well, multi-thermal fluids, heavy oil reservoir, three dimensional experiment, parameter optimization
