  • The clay stabilizer used in slick water fracturing fluids has the following problems such as poor compatibility, high consumption, poor inhibition to clay swelling and difficulty in solution making in field operations. A new cationic clay stabilizer, SRCS-1, has been developed to try to solve the aforesaid problems. SRCS-1 has good compatibility with the anionic polymer drag reducers used in slick water. The percentage of clay cores swelling tested with 0.3%SRCS-1 is 68.2%, better than those clay stabilizers collected from operation fields. The swelling inhibition mechanism was analyzed by measuring the surface tension, ζ potential and particle size distribution. SRCS-1 has been used in the slick water fracturing in the well Kongshen-1 in Xinjiang, and the water solution was prepared very easily and fast. The SRCS-1 had good compatibility with other additives used, and good inhibitive capacity. The slick water made had stable properties and the fracturing jobs were successful.
