摘要
在分析大牛地气田碳酸盐岩储层地质特征的基础上,针对储层改造现状和改造难点提出了转向酸酸压技术。从理论和实验方面分析了转向酸体系的转向机理;通过流变性能、酸岩反应动力学、转向性能及破胶性能实验,分析了转向酸体系的综合性能;最后在×井试验应用了转向酸酸压工艺,取得了大牛地气田碳酸盐岩储层勘探开发的突破。
This paper proposed the acid fracturing technology with diversion acid based on the analysis of geology characteristics of carbonates reservoirs in Daniudi Gas Field and aimed at the reservoir stimulation status and difficulties. The diversion mechanism was analyzed from theoretical and experiments. The performance of dive.ion acid system was studied by experiments on rheological properties, acid-roek reaction kinetics, dive.ion and broken plastic property. The acid fracturing technology with diversion acid is applied in one well, making a breakthrough of exploration and development of carbonate reservoir in Daniudi Gas Field.
