草南95-2井组火烧油层矿场试验

Field test of fire flooding in Caonan 95-2 well group of Le'an Oilfield

介绍了乐安油田南区草南 95 2井组火烧油层室内研究和现场试验 .室内研究确定了现场试验主要参数 (包括油层点燃温度、空气需用量及注气速度、燃料含量、点燃时间等 )及动态监测方法 .现场试验表明 ,草南 95 2井组成功实现了通电点火 ,燃烧过程参数的正确确定 ,保证了油层的持续燃烧 ,使火烧试验得以顺利进行 .同时对火烧油层的效果进行了初步分析 ,得到了该区火烧采油的一些规律性认识 。

The laboratory experiment and the field test of fire flooding of Caonan 95-2 well group are carried out. The laboratory experiment aims at determining main parameters and dynamic monitoring method for field test. The parameters include firing temperature, air supplying rate, fuel content, firing time, and so on. The field test shows that, the determined parameters ensure the successful ignition and combustion of the fire flooding. Some regular cognition of fire flooding in this region is obtained, which can be used for guiding the further development of Le'an Oilfield.
