Abstract: | In this work, the ultra-low-density ceramsite proppant was first prepared using bauxite waste rock as the main raw material. The effects of raw material pre-calcination, sintering temperature, sintering time and additive dosage on proppant performance were studied. The test results showed that under the conditions of the pre-calcination time of 2 hours in 750℃, the additive CMC dosage of 1.5%, calcination time of 150 min in 1 320℃, the bauxite waste rock could be prepared into ceramsite proppant with the size of 0.42 and 0.84 mm, volume density of 1.42 g/cm3, the apparent density of 2.55 g/cm3, the breaking rate of 5.35% at the closing pressure of 52 MPa. All indicators were in line with the national oil and gas SY/T 5108-2014 industry standard requirements. |
