Abstract

As the challenges associated with developing carbonate reservoirs intensify, acidized fracturing has emerged as a crucial method for facilitating the efficient extraction of oil and gas. Slickwater fracturing fluid is the most commonly utilized among these options. Nevertheless, its drag reduction capabilities are notably diminished under acidic conditions. In this work, an acid resistance drag reducer PL was selected as the primary material for preparing the acid slickwater, and the concentration of additional additives was optimized. The final formula for the acid slickwater was obtained: 20% HCl + 0.1 wt% PL + 0.05 wt% LQ-B + 0.1 wt% CP-1 + 0.3 wt% CS-1. The rheological and drag reduction properties of the acid slickwater were systematically evaluated. The acid slickwater is a typical pseudoplastic fluid with significant viscoelastic properties. At the displacement of 40 L/min, its drag reduction rate is 75%. In addition, the retention rate of drag reduction exceeded 90% under sustained shear conditions. The acid slickwater developed in this study offers technical support for the effective extraction of resources from deep carbonate reservoirs.
