本文介绍用声波全波测井资料确定岩层机械特性,其中包括五个弹性模量,三个应力参数,进而确定防止岩层自然破裂引起钻井泥浆漏失的井柱压力极限值、增产措施需要的压开岩层的压裂梯度值和采油出砂的生产压差极限值。这些数据提供生产使用是有价值的。
This paper introduces the use of sonic full-wave logging data to determine the mechanical properties of rock strata, including five elastic moduli and three stress parameters to determine the wellbore pressure limit to prevent the leakage of drilling mud caused by natural rupture of rock strata. Fracturing gradient of rock formation and production pressure difference of sand production. These data provide valuable information for production use.
