摘要: 本文重点根据全波测井资料,结合补偿密度测井资料求解动弹模量的方法来研究储集层的力学性质、岩性的识别方法、岩层的破碎情况,以及孔隙中流体性质对这些参数的影响等。并给出了体变模量、宏观压缩系数和孔隙度之间的关系式。文中提出的测井与实验室观测到的纵波与横波首波相位相反、长源距全波测井中声波在井内流体中的传播时间确定方法、及以井内泥浆速度传播的流体波是沿井璧传播的观点,都只有实际意义。并在全波分析中起着重要的作用。

Abstract: Based on the full wave log and combined with compensated densilog, this paper puts forward a method of extracting dynamic elastic modulus for studying the mechanical properties of reservoir, identification of lithology, rock breaking in the formation, and the effect of the properties of fluid in the poreson these parameters. The relationship between bulk modulus, macro-compressibility and porosity is also given. The author has proposed a method of determining the acoustic transit time through fluid in the well by long-spacing full wave logging and pointed out that the phase of head waves of P and S-wave logged and observed are in opposition and that the fluid wave is transmitted at the speed of mud along the wall of the well.All these are valuable to the analysis of full-wave logs.
