摘要
To the gas field had been developed for a long term, the yield is hard to keep a high value.How to improve the daily production is a key problem.Fracturing again in old wells can be an effective method to solve the problem.In this paper, we introduce this technique.We choose well and layer firstly, and then decide a suitable fracturing measure.Finally, fracturing evaluation shows the method can improve the yield effectively.This experience can be popularized.
