CT降滤失酸的性能与现场应用

THE RESEARCH AND FIELD APPLICA- TION OF CT LOSS CONTROL ACID

CT降滤失酸是西南油气田分公司天然气研究院研究开发的一种新型酸液体系。该体系自1999年12月在天东59井进行了第1口井现场试验以来,已在重庆气矿天东29等4口气井进行了酸化施工。其中天东29等3口井获得增产,施工有效率75％,每天增加井口天然气产能29.73×10~4m^3文中详细介绍CF降滤失酸的性能及现场应用情况。

CT loss control acid is the newest acid izing fluid system. It is developed by the Research Institute of Natural Gas Technology, Southwest Oil and Gas Field Company of PetroChina. This article introduces the performance and field applications of the CT loss control acid. This acid have used in well TianDong 59,29,67, 84. Its effectiveness is high up to 75% .Well Tiandong 29,67,84 obtain increase productivity and a verage enhance production 29.73 x 104m3/d.
