Abstract: Compressibility evaluation of oilfield formation is the key problem in hydraulic fracturing and is directly related to the final production increase. In this paper, the compressibility evaluation on the deep rock in one block of Qinghai Oilfield was carried out. Brittleness index was characterizated quantitatively through defining the crack description index and combining it with two calculation methods of rock mechanics parameters and residual stress. Plasticity index was also characterizated q... More
