摘要
本文阐述了针对陕甘宁盆地中部气田碳酸盐岩低渗储层的特点，采用系统工程方法开展的多级注入闭合酸压技术研究，介绍了利用研制的多级注入、二维及拟三维酸压设计软件模拟研究所获得的一些重要认识；提出了该项技术的现场设计原则及效果评估方法，介绍了现场应用效果。文中强调指出，对低渗及特低渗碳酸盐岩气藏，多级注入闭合酸压技术是最好的增产措施。
This paper expounds the study of multiple injection closed acid—fracturing technology,which is developed by system engineering method in accordance with the low permeability gas reservoir in the centre port of Shanganning basin. It introduces some importunt conclusions from simulation research on the computer softwares for multiple injection, two- dimensional and pseudo - three - dimensional acid—fractuing design, and presents the design principle and results evaluation method of field treatment, as well as field appliaction results. The paper stresses emphatically that the multiple injection closed acid-fracturing technlogy would be a best method to increase the preduction of carbonate gas reservoir with low permeability or poor Permeability.
