摘要
CT降滤失酸是西南油气田分公司天然气研究院近年来研制的一种新型酸液体系。该体系以控制酸液滤失为主要特点 ,较好的解决了酸化施工时酸液的滤失。在现场施工中 ,无论是新井还是老井的重复酸化施工均取得了很好的施工效果。在已进行的 6口井施工中 ,施工有效率达 83% ,每天增加井口天然气产能近 30×10 4m3 。文章简要介绍了CT降滤失酸的性能及现场应用情况。
CT fluid loss acid is a new acid liquid system developed by the Natural Gas Institute of PCL Southwest Branch in the resent years. The system is characterized by controlling acid liquid loss and further solves the problem of acid liquid loss during acidizing treatment. With the system,good results have been achieved for the acidizing treatment of new wells or the repeat acidizing treatment of old wells. The effective rate of acidizing treatment reached to 83% in the 6 wells that had been treated. And the gas productivity of the well head increases about 30×10 4m 3/d. The article introduces the property and field application of CT fluid loss acid briefly.
