Abstract

The Ordovician carbonate reservoirs are heterogeneous with low formation pressure, low permeability in Changqing gas field. Multistage Acid Fracturing is a key technology for further stimulation in this field. This paper presents the technique mechanism, suitability analysis, lab experiments evaluation, optimization of key parameters, application results, and so on of this technology.
