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.

与此同时即可进行生产，开始膨胀进程，或者将当前流体引入封隔器以引起膨胀，也可直接循环专用膨胀液。

At that point either produce the well to begin the swelling process or allow the current well fluid to swell the packer systems prior to operations or circulate down the designed swelling fluid.
