CORRELATION BETWEEN LOGGING DATA AND ROCK MECHANI- CAL PARAMETERS AND ITS APPLICATION IN CALCULATION OF SIDEWALL MECHANICAL STABILITY

    摘要
  • 摘要: 应用大庆头台和茂兴地区5口井的测井资料,14块岩心的室内试验数据,找出了该区块不同岩性在相应围压下的静、动态岩石弹性参数的相关性,根据线弹性理论以及岩石的破坏准则建立了井壁稳定性条件,确定了井壁破裂和坍塌的3个临界压力剖面,结合孔隙压力确定了头台和茂兴地区的安全钻井液密度剖面。

     

    Abstract: Using logging data from 5 wells in Toutai and Maoxing areas in Daqing and laboratory data obtained from 14 cores,the correlation of static and dynamic elastic parameters under corresponding confining pressures in various lithologies in these areas was found. Based on line elastic theory and rock break machenism,the sidewall stability condition was established. Three critical pressure profiles for sidewall breaking and sloughing were defined. Considering pore pressure, safety profiles of drilling fluid density in Toutai and Maoxing were further defined.
