Section water ring: prevent concentration in the peripheral Settings, seepage, to change the direction of flow, increasing permeability diameter, reduce the seepage.

截水环：防止集中渗流，在外围设置，以改变水流方向，增加渗径，减小渗流。

Peripheral oilfields are also the main direction to increase recoverable reserves, but 90% reserves are located in ultra-low abundance, ultra-low permeability and complex fault-block reservoirs.

外围油田也是增加可采储量的主要方向，但90%的储量位于特低丰度、特低渗透及复杂断块油藏。
