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。
This paper focuses on the study of the mechanical properties of reservoirs, the identification of lithology, the fracturing of rock formations and the properties of fluids in the pores based on the data of full-wave logging and the calculation of dynamic modulus by compensated density logging data Influence and so on. The relationship between bulk modulus, macroscopic compressibility and porosity is given. In this paper, the logging and laboratory observations of the P-wave and S-wave are opposite in phase. The method of determining the propagation time of sound waves in the well from the full-bore well logging well and the fluid wave propagating in the well mud velocity are along the well Bi spread point of view, only practical significance. And plays an important role in full wave analysis.
