Brittleness determines the effect of reservoir fracturing and is the key to improve unconventional oil and gas production. In order to accurately understand the brittleness and fracture parameters of the reservoir, triaxial compression test and stress-strain analysis were carried out on the Chang 7 rock samples from well N-1 and well Z-1 in Longdong area of Ordos basin, based on which, the brittleness index was calculated. The results show that the brittleness index calculated by stress-strain method is 51.95%-52.96% and by mechanical parameters method is 57.2%-57.5%; the brittleness index is high, indicating that chang7 reservoir in Longdong area has high brittleness, which is conducive to later fracturing.
