地球物理测井数字化包括仪器数字化和解释方法数字化,仪器数字化是实现方法数字化不可缺少的条件。在测井作业中,每一根井下探管探测到的地球物理参数有多种,如果直接将探测信号经电缆传送到地面仪器,受各种因素影响,信号失真度偏大。本文通过对测井曲线特征的分析和认识,掌握定性划分砂泥岩剖面储集层的基本方法,并应用阿尔奇公式,进行储层参数的计算。
Digitization of geophysical logs includes digitization of instruments and interpretation of methods Digitization of instruments is an indispensable condition for digitalization of methods. In well logging, there are many kinds of geophysical parameters detected by each downhole probe. If the probe signal is directly transmitted to the ground instrument via cable, the signal distortion is too large due to various factors. Based on the analysis and recognition of the logging curve characteristics, this paper grasps the basic methods of qualitatively dividing the sandstone and mudstone reservoirs and applies Archie formula to calculate the reservoir parameters.
