Abstract

In order to make up for the lack of high temperature resistance, the high temperature seawater-based fracturing fluid with temperature 180℃ is developed with the self-developed high temperature seawater based frac agent HYCF-5 and its supporting seawater-based reversible cross joint agent HYCF-B, efficient chelating agent HYCF-S, high temperature stabilizer HYCF-C, performance regulator HYCF-D, anti-swelling agent HYAS-1, cleanup additive HYCF-F. Through the performance evaluation of the high temperature seawater-based fracturing fluid, the performance evaluation of high temperature seawater-based fracturing fluid and the performance research and evaluation of the high temperature seawater-based fracturing fluid, the correlation can be met by the standard of oil and gas industry standard SY/T 6376-2008 the technical conditions of fracturing liquid. At the same time, the paper shows the high suspension sand advantage and low damage mechanism of high temperature seawater-based fracturing fluid, and provides sufficient theoretical reference and technical support for the field application.
