| Abstract: |
| Abstract:Based on analysis of the mechanics of acid rock reaction and characterization of Palaeozoic carbonatite gas reservoir of Daniudi gas field, an optimal research of the reform strength and series of multiple injection acid fracturing were carried out by numerical simulation. The acid fracturing modification effect under different injection stages by the experimental data was analyzed, and the result showed that the multiple acid fracturing technology was feasible, and the absolute open-flow could reach 38 200 m3/d in the Daniudi gas field. |
