摘要:

针对塔里木盆地部分地区井壁不稳定问题,开展井壁稳定性测井评价研究,主要从岩石力学的角度出发,利用测井信息计算地层岩石机械特性参数、地层孔隙压力、地应力分布、破裂压力等

,进而得到安全的钻井液密度范围,为钻探提供合理的工程参数。

Abstract: Aiming at the problem of borehole wall instability,researching the method of well logging evaluation for borehole stability in Tarim Basin is studied.Based on rock mechanics,the logging data are used to calculate the parameters of rock mechanical property,formation pore pressure,geo-stress and break pressure and so on.And the secure window of mud density is obtained,so the reasonable engineering parameters for the drilling is provided.

Key words: Tarim Basin, borehole wall stability, logging technology, geo-stress, break pressure, secure window of mud density
