line clearance with water

Three reasons have been analyzed in the paper that influences the effect of top water exclusion: brief cycle of water exclusion;reverse flow lead to polluting reservoir in pump inspection;the casing status getting bad.

分析了造成套损井隔水采油有效期短、检泵时水层倒灌污染油层、套管状况差等影响隔水采油效果的原因。

The main treating is top water exclusion technology.

长庆油田存在严重的套管腐蚀损坏,采取的主要治理措施是隔水采油工艺技术。

In order to decrease the cost of ocean oil storage and prevent pollution of traditional oil and water replacement,a new idea about underwater oil storage with separate replacement of oil and water was put forward.

为了降低海上油田开发中原油储存装置的造价,并防止传统油水置换水下储油引起的污染,提出油水隔离置换的水下储油思路。

Based on the use requirement of sea-based oil storage exploration model and oil interlayer, three different types of oil tanks are designed.

为此,本文提出了油水隔层的新设计,介于油水之间,避免油水接触。
