late development stage

Most of the water-flood reservoirs have been in the late development stage, of which the water cut is more than 90%.

我国大部分注水开发油田已处于开发后期，油井含水高达90%以上。

Blocking of pay zones by water often occurs in gas producers, especially during the middle-late development stage or when the producer is invaded by coming fluid.

气井产层水堵是一种普遍现象，尤其是开发中后期或遭受外来液体侵入的气井则更为严重。

However, in order to achieve portability and extensibility, ideally we would like to defer inclusion of those details to a very late stage in development.

然而，为了实现可移植性和可扩展性，理论上我们想要推迟到开发的非常晚的阶段在加入那些细节。
