岩石力学参数的特征分析可以应用于地应力研究、钻探开发和压裂生产等方面.本文对川西须五段砂、泥岩运用MTS岩石物理测试系统开展了声学和力学的实验测试.分析了岩石力学参数在饱气饱水阶段变化时的特征,并在实验基础上拟合出弹性模量和泊松比的动静转换公式.最终获得川西须五段各井岩石力学参数测井解释剖面.
巖石力學參數的特徵分析可以應用于地應力研究、鑽探開髮和壓裂生產等方麵.本文對川西鬚五段砂、泥巖運用MTS巖石物理測試繫統開展瞭聲學和力學的實驗測試.分析瞭巖石力學參數在飽氣飽水階段變化時的特徵,併在實驗基礎上擬閤齣彈性模量和泊鬆比的動靜轉換公式.最終穫得川西鬚五段各井巖石力學參數測井解釋剖麵.

Characteristic analysis on rock mechanical parameters can be used for the initial stress research,drilling and fracturing production.The acoustic and mechanical tests for sand and mud rock in Chuanxi Xu-V formation are carried out in this paper by use of Machine Test System.Analysis of the rock mechanical parameters in the full aeration and water phase is conducted as well.The elastic modulus and poisson's ratio of dynamic and static conversion formula is worked out based on these experiments.Therefore,the rock mechanics parameters and logging interpretation profile of wells in this formation are obtained.
