地球物理测井是一种使用电子仪器对地层获取定量情报,为认识和掌握石油地质规律提供重要依据的测量工作。测量的水平,测量结果的可靠性及对测量工作的评价全在于其精度。它不仅对质量起着监督和保证作用,而且也住往是测量工作成败,成果优废的一项决定性因素。测量精度的提高以及对测量误差的深入研究往往成为带根本性的技术改进的前导。因此,精度评价问题在测井技术迅速发展的今天,尤其具有重要意义。本文从基本概念入手,结合目前测井状态,进行了简单的精度分析,提出一些计算方法,与读者讨论。
Geophysical logging is a kind of measurement that uses electronic instruments to obtain quantitative information of formation and provides an important basis for understanding and mastering the laws of petroleum geology. The level of measurement, the reliability of the measurement results, and the evaluation of the measurement are all due to its accuracy. It not only plays a supervisory and assurance role on quality, but also serves as a decisive factor in measuring success or failure of work. Increasing measurement accuracy and in-depth study of measurement errors are often the precursors of fundamental technical improvements. Therefore, the problem of accuracy evaluation is of great importance today when logging technology is rapidly developing. This article starts with the basic concepts and combines the current state of logging with a simple precision analysis, puts forward some calculation methods and discusses with readers.
