测井技术已经有五十年的历史。目前,测井方法已发展到四、五十种。仪器设备由于微电子学的进步达到了高度的现代化;在资料的处理和解释工作中普遍地使用数字电子计算机,实现了自功化;借助于于现代的微波技术或卫星通讯,可以及时而不失真地远距离传输测井信息。目前,用于裸眼井的测井仪器日趋定型。裸眼井测井仪器大致分为三类。(一)电法测井 Logging technology has been fifty years old. At present, logging methods have been developed to four or fifty. Instruments and equipment due to advances in microelectronics reached a high degree of modernization; in the data processing and interpretation work commonly used digital electronic computer, to achieve self-improvement; with the help of modern microwave technology or satellite communications, can be timely and not Distortion of long-distance transmission of logging information. At present, logging tools for openhole wells are becoming more and more stereotyped. Open-hole logging tools can be roughly divided into three categories. (A) electrical method logging
