Abstract: Locating the combustion front timely is helpful to production control. The prediction methods of combustion front used in field were researched, then a set of application method specific to reservoirs with different feature was obtained. Infrared photography was suitable for shallow layer reservoirs, and direct testing method using thermometric component was suitable for reservoirs with intensive observation well and production well. Method combining production performance and material balance was suitable for homogeneous reservoirs with regular well pattern, and method combining tracer monitoring and production performance was suitable for heterogeneous reservoirs or reservoirs with irregular well pattern. The pressure drop test method was so complicated that it needed further study. At last the suggestions were proposed that on the basis of geological screening in advance, the aim of "less air injection and more oil production" should be achieved, besides, the management of production well should be strengthened by combining analysis of production performance, so that the combustion front could be moving forward evenly and steadily.

摘要： 及时掌握火驱过程中火线的位置, 有助于进行生产调控, 通过调研现场预测火线位置的方法, 得出一 套针对不同特征油藏的适用方法: 红外照相法适用于浅层油藏; 用测温元件直接测试法适用于观察井和生产井密集 的油藏; 生产动态和物质平衡相结合的方法适用于均质性好且井网形式规范的油藏; 示踪剂监测和生产动态相结合 的方法适用于非均质性严重或井网形式不规范的油藏; 压降试井法由于计算复杂, 有待进一步研究。最后指出应在 前期地质筛选的基础上, 做到“ 少注气、 多采油” , 并结合生产动态分析加强对油井的管理, 引导燃烧前缘均匀稳定的 推进。
