封隔器两种最常见的形式是生产封隔器或者测试封隔器和膨胀式封隔器。
The two most common forms are the production or test packer and the inflatable packer.
而膨胀式封隔器的膨胀则是通过泵送流体进入囊状物，与气球大约同样的方式，但是比气球具有更坚固的结构。
The expansion of the latter is accomplished by pumping a fluid into a bladder, in much the same fashion as a balloon, but having more robust construction.
生产封隔器或者测试封隔器可能下入下套管的井段，而膨胀式封隔器可以在裸眼井段使用，也可以在下套管井段使用。
Production or test packers may be set in cased holes and inflatable packers are used in open or cased holes.
