现在,几乎所有勘探井的测井程序中都包括某种速度测井,甚至越来越多的开发井和评价井也都作速度测量。对于勘探人员和采油人员来说,有许多重要的参数都可以从速度测井及测量资料中推算或估算,如: (1) 控制地震资料的速度随深度分布曲线 (2) 用来分析对比反射资料的合成地震记录 (3) 有关岩性的变化和构造信息 (4) 流体成分和孔隙率变化的测定 (5) 超压带的辨认所有这些用途都要求很好地控制资料采集和了解声波传播的基本原理。资料采集、分析和解释等方法所固有的局限性都应仔细地加以权衡,因为它的影响可能随着资料使用目的的不同而有所变化。
Almost all exploration wells now include some speed logging in their logging procedures, and even more and more development and evaluation wells are making velocity measurements. There are many important parameters that can be estimated or estimated by speed logging and measurement data for surveyors and oil producers such as: (1) The velocity of seismic data is controlled by the depth profile (2) to analyze the contrast reflections (3) Changes in lithology and tectonic information (4) Determination of changes in fluid composition and porosity (5) Identification of overpressure zones All of these uses require good control of data acquisition and understanding of sound wave propagation The basic principle. The limitations inherent in methods such as data collection, analysis and interpretation should all be weighed carefully, as their impact may vary depending on the purpose of the data used.
