摘要
针对目前对岩石压缩系数研究的诸多争论,在细致深入分析的基础上,重新推导建立了岩石压缩系数的新关系式,克服了李传亮教授所建立关系式的不合理现象。通过对比分析证明该关系式是正确的,李传亮教授所建立关系式在物理意义及数量关系上都是不正确的。指出,体积法测量的孔隙压缩系数数值偏高,存在逻辑反转现象,但与微间隙和封套存在塑性变形关系不大,主要是因反映到规律层面的数据处理统计不合理所致。
In view of the present arguments about＇compressibility study, through in-depth analysis, new compressibility relationship is established by derivation, which overcomes the paradox phenomenon on formula given by Prof. Li Chuan-liang. The correlation and analysis in this paper indicate that this relationship is correct, and Li＇ s formula is wrong in both physical meaning and quantity relation. It is con- cluded that the pore compressibility measured by volumetric method is higher than the actual one and there is a logic reversal phenomenon, which is not closely related to micro clearance and covers with plastic deformation. The main reason is that unreasonable data processing statistics results in that the compressibility of rock is higher than that of formation fluid.
