“…[5][6][7][8][9] There are two ways to increase the retardation rate: one is to reduce the diffusion rate of the hydrogen ions by increasing the viscosity of acids. 6 and the other is to separate the acid solution from the rock by forming a lm on the rock surface, thus reducing the reaction rate between the acid and the rock. 10 Recently, gelled acids have effectively improved the permeability of reservoirs as retarded acids have attracted the interest of many researchers.…”

“…Conventional hydrochloric acid (HCl) is the most widely used acid system for the stimulation of carbonate reservoirs. However, the fast reaction rate between the HCl and carbonates causes most of the acid consumption near the well reservoir, and the acid cannot penetrate the deeper places of the carbonate reservoir; this limits the application of acidizing modifications.…”

The fast reaction rate between hydrochloric acid and carbonates causes the most acid consumption near the wells, and the acid cannot penetrate the deeper places of the carbonate reservoir; this limits the application of acidizing modifications for the reservoir. In this study, we chose acrylamide, 2-acrylamido-2-methyl-1-propane sulfonic acid (AMPS), allyl alcohol polyoxyethylene ether (APEG), and N-dimethyl-N-vinyl nonadecan-1-aminium chloride (DMAAC-18) to synthesize a quadripolymer (MCJS) that could reduce the reaction rate mentioned previously. The molecular structure of MCJS was characterized by Fourier transform infrared and 1 H-NMR spectroscopy. The molecular weight and molecular weight distribution of MCJS was determined by gel permeation chromatography. Carbonate rock was analyzed by X-ray diffraction and energy-dispersive X-ray spectroscopy. The retarding properties of the acid mixed with MCJS (MCJS acid) were investigated, and the resulting reaction rate between the acid and carbonate decreased obviously, even at a low viscosity. Scanning electron microscopy and core flood experiments showed that the MCJS could be adsorbed on the carbonate rock surface and form a hydrated film that delayed the reaction.
