The bilayer well completion-water drainage-oil production technology can inhibit the bottom-water coning to tap the productive potential of the reservoir and improve the development result of it.
双层完井排水采油技术可以抑制底水锥进，达到解放油层生产潜力、改善油藏开发效果的目的。
The coning of bottom water will happen as soon as the producing pressure drop of a well is higher than the difference of gravity caused by the difference of density between oil and water.
当油井生产形成压力降落大于油水密度差引起的重力差时，砂岩底水油藏锥进即会发生。
Inhibiting water coning by water recovery from the oil reservoir with active bottom water can inhibit or slow down bottom water coning, stabilize oil production and control water cut.
对于底水能量较活跃的油藏，可利用采水抑锥工艺抑制或减缓底水的锥进，从而达到稳油控水的目的。
