| Abstract: | The gas reservoir in Yuanba area is deep and of high temperature, and contains acidic corrosive gases. In view of the technical difficulties with regard to the transformation of gas reservoir in Yuanba area with acid fracturing technology, a lot of laboratory investigations and field experiments have been conducted, and the technologies of gelled acid and closed acid fracturing, vibrated acid fracturing, combined operation of super positive - pressure perforating and acid fracturing testing, acid fracturing testing string structure optimization and reasonable design of construction parameters, high - density acid fracturing, and composite clean-up, etc. have been developed. The production was increased by 68.9 times in the field test conducted in Yuanba area, which marks an important breakthrough of the transformation of high temperature and high sulfur reservoir with acid fracturing technology. |
