Sinopec Research Institute of Petroleum Engineering, Beijing 100101;3. China University of Petroleum, Beijing 102249) Abstract Acid fracturing with sand carrying acid has become one of the important measures in carbonate reservoir stimulation. The key to the success of acid fracturing with sand carrying acid is the selection of a high temperature sand carrying acid with good performance. To deal with problems encountered in fracturing, such as shear-breaking of the crosslinked acid by shearing, serious de-acidification, high crosslinking agent consumption and high job cost etc., a new hydrophobically associating thickener (used in acid) and a high performance crosslinking agent have been synthesized, and an optimum crosslinked acid formulation developed with the following composition: 20%HCI+0.8%SRAP-1 (thickener) + 0.8% SRACL (2 :10, crosslinking agent )+2%SRAC-1 (high temperature corrosion inhibitor)+0.2%DF-1 (iron ion stabilizer) + 1.0% SRCU-1 (cleanup additive)+0.05% JSP-8 (capsule gel breaker). Laboratory evaluation showed that the crosslinking time of the acid formulation was about 89 s even after substantial decrease in the amount of crosslinking agent, indicating that the acid formulation has good delayed crosslinking ability. After shearing for 2 h at 140 °C and 170 s-', the viscosity of the acid was still greater than 60 mPa - s, and the state of the crosslinking remained stable, no de-acidification
was found of the acid. The acid formulation has satisfied the need of field operation, and is worth popularizing Key words Carbonate reservoir; Crosslinked acid; Acid fracturing; Sand carrying acid
