The practice and cognition of fracturing in the development of Shanian Oilfield with low permeability

Shanian Oilfield, which consists of many small fault blocks, is a low permeability and extremely low sandstone reservoir. Unfortunately, the productivity, injectivity index and heterogeneity are unfavorable. According to the special characteristics of the geology in this area, we put forward fracturing to improve the effect of development. At the same time, we optimize fracturing design and the effect of fracturing is very obvious. Finally, both the applicable condition and work experience are suggested in this paper.
