盐穴储气库造腔井油水界面位置控制方法

The controlling of the oil-water interface in salt gas storage leaching well

盐穴储气库水溶造腔过程中,为防止腔体上溶过快,丢失有效体积,必须严格控制油水界面的位置。金坛盐穴储气库经过长期的摸索与实践,发展了地面观察法、压力表对比法、计算法、电测法、井下传感器法等五种油水界面控制方法,在盐穴储气库造腔过程中已经得到广泛应用,其它方法如光纤式连续油水界面测量也在不断摸索与试验中。

During the process of solution mining leaching in gas storage, to prevent the fast solution of the top of the cavern, we must control the oil-water interface. On the base of long time seeking and practice, Jintan salt gas storage developed five methods, like observation method on ground, pressure gauge comparison method, estimation method, well logging with electric method, downhole transducer method and all these methods have been taken into apply,other method like optical fiber for oil-water interface is also being studied.
