- 摘要:
- 泡沫排水由于操作简便、成本低，在产水气井排水采气中得到广泛运用。但是在排出液体中含有大量泡沫，严重影响气液分离和脱水效果。因此，消除产出液中的泡沫显得尤为重要。传统液体消泡工艺存在消泡剂用量不易控制、消泡效果差、运行成本高以及在寒冷冬季运行不稳定等难题。近年来，国内研发出了固体消泡棒和与之相配套的加注装置，很好地解决了这些问题。在固体消泡工艺发展现状调研的基础上，对比了液体和固体两种消泡工艺的优缺点，并针对固体消泡工艺在目前适用过程中存在的缺陷和可能出现的问题进行了整理分析，提出了相关建议，有利于泡沫排水采气工艺的进一步发展。
Foam drainage has been widely used in water production well gas recovery due to its easy operation and low cost. However, a great deal of foam in discharging liquid will seriously affect the gas-liquid separation and dehydration effects. Therefore, it is particularly critical to remove foams in the produced liquid. Traditional liquid defoaming processes have such disadvantages as hard to control the amount of defoaming agent, poor defoaming effect, high operation cost and unstable performance in the winter. In recent years, solid defoaming rods and defoaming agent injection device matched with such rods have been developed in China and above shortcomings have been covered effectively. Conducted are researches on mechanism and development status of the solid defoaming agent and analysis on present situation and the common operation problems of this technology and proposed are some applicable suggestions, which will be beneficial to more widely application of the foam drainage gas recovery.
