Forming a gas cap with the injected gas;

用注入的气体形成气顶；

Limit of secondary gas cap

次生气顶边界

Make sure your gas cap is securely tightened.

确保油箱盖安全地拧紧了。

Gas cap field are usually developed by natural depletion and water flooding.

国内外对于气顶油田的开发主要是采用衰竭式和注水开发方式.

Gas may be found either dissolved in reservoir fluids or as free gas that tends to form a gas cap beneath the top seal on the reservoir trap.

气体可能在储层流体中以溶解形式或作为游离气而存在，游离气趋于在储层圈闭的盖层下面形成气顶。

With further understanding of gas cap reservoir recovery mechanism and the progress in technology, obstruction recovery method has become an important method for developing gas cap field.

随着对气顶油田开采机理认识的深化和工艺技术的进步，目前隔障开采已成为气顶油田开发中重要方法之一。

The horizontal well is an effective way to avoid early gas breakthrough of gas cap reservoir and the identification of its optimal vertical location is the key to obtain the best development result.

水平井开发油藏是避免气顶油藏过早见气的有效手段，而确定水平井最优垂向位置是获得最佳开发效果的关键。
