Coning can also occur by drawing down the gas-oil contact around a well.
围绕一口井下拉油气界面也会出现锥进。
The gas-oil contact is a transitional zone that goes from high oil saturation to high gas saturation with a thickness of up to several feet.
油气界面是从高含油饱和度至高含气饱和度的一个过渡带,其厚度达几英尺。
This paper gives a summary of the techniques for monitoring, controlling the gas-oil contact as well as the techniques used in the adjustment of the development program.
