Kaiser effect point identification method and in-situ stress prediction of reservoirs

Autor: KONG Zheng, ZENG Jianhui, ZUO Mingsheng

Publikováno v: Youqi dizhi yu caishoulu, Vol 30, Iss 6, Pp 54-60 (2023)

There are multiple mutation points in the acoustic emission （AE） cumulative curve in the Kaiser experiments of reservoir cores， causing the routine Kaiser effect point discriminant method to be inaccurate， and there is even a problem that the
