CT5--2 Foaming Agent for Fluid Withdrawal by Foam from Gas Wells

本文研制的气井泡沫排液起泡剂CT5-2,经室内和现场试验表明,CT5-2适用于含凝析油高矿化度地层水、井温较高的天然气井排除积液。CT5-2还可与缓蚀剂CT2-11复配,用于含硫气井排除积液。CT5-2也适用于一般气水井。具有用量少、排液效率高、不污染地层等特点,可在各类气田推广应用。

Indoor and work-site tests indicate that the introduced CT5—2 foaming agent for fluid withdrawal by foam from gas wells is suited to the gas wells with condensate, high salinity formation water and higher temperature. It can be used for fluid withdrawal from the gas wells containing hydrogen sulphide being prepared with CT2—11 corrosion inhibitor, and can be also used for common water-gas-producing wells. This foaming agent has many advantages such as small quantity needed, high fluid withdrawal efficiency and no formation damage etc., so it may be spread and applied in various gas fields.
