准噶尔盆地中部区块地应力求取研究
Investigation of Terrestrial Stress in Middle Zhunger Basin
【摘要】 介绍了古地磁测试结合差应变分析确定地应力参数的基本原理以及分析方法。应用该方法求取了准噶尔盆地中部区块最大主应力的方位角(最大主应力的方位角为175°-185°),与地层倾角测井资料进行了对比,结果较为一致。这说明古地磁测试结合差应变分析确定地应力是一项准确可靠的室内测试方法,同时分析结果也为该区块的钻井工程设计与施工提供了基础数据。
【Abstract】 This paper introduces the principles and analysis method of how to determine the terrestrial stress using the archeomagnetism measurement combined with differential deformation analysis.The azimuth of maximum principle stress in middle Zhunger Basin is 175° to 185° using this method.This result agrees with the formation dipping logging.The results indicate that terrestrial stress determination using archeomagnetism measurement combined with differential deformation analysis is accuracy and reliable experimental method.The analysis results provide the basic information for the drilling design and implementation in this area.
