Aimed at the difficulty of achieving high and stable production in the tight carbonate gas reservoir，the feasibility of volume acid fracturing to lower Paleozoic tight carbonate gas reservoir in Ordos basin was analyzed with reference to the volume fracturing for shale gas in foreign countries. Firstly，stimulation mechanism of the volume acid fracturing in the tight carbonate gas reservoir was introduced. Based on this，the advantage and limitation of the volume acid fracturing for the development of the tight carbonate gas reservoir were analyzed on reservoir fracturing probability，natural fracture development，horizontal principal stress difference，intersection angle of natural fracture and hydraulic fracture，and the solution for the limitation was put forward. The study results show that the volume acid fracturing can form complex fracture network，and gain larger stimulated volume of reservoir. The stimulation effect of the volume acid fracturing is closely related to the reservoir fracturing probability，natural fracture development，intersection angle of natural fracture and hydraulic fracture.The large horizontal principal stress difference will has disadvantage impact on the fracture network formation，which may be removed by the degradable fiber diversion technology or self-diverting acid fracturing. The results of pilot test indicate that gas production of 18 gas wells after volume acid fracturing exceed that of adjacent gas wells of conventional acid fracturing by more than 60%，and the daily gas production of volume acid fracturing in 7 wells exceed that of conventional acid fracturing by more than 41% after one month. It shows that stimulation effect of the volume acid fracturing is better than that of the conventional acid fracturing for lower Paleozoic carbonate gas reservoir in Ordos basin，and the volume acid fracturing has a good prospect of application in future.
