由于海上平台钻井与陆地复杂条件下钻定向斜井的实际需要,随钻测井(在钻井过程中测井)一直在不断发展。五十年代就发展了电缆式测井仪,至今这种仪器仍在改进与应用。它仅能测量井斜、方位、温度,由井下定时照像记录发展到地面数字记录与计算机控制。而后,又发展了不用电缆的随钻测井仪,研究了用泥浆传递信号的测量系统。目前了解:美国从事随钻测井研究与生产的公司有东方人造斜公司、斯仑贝谢—分析者公司、吉哈特公司、科学控制钻井公司等。采用泥浆遥测系统的随钻测井已投入了商业性服务,而且它的服务项目日益增多,除了提供井的方位、水平漂移(井斜)、钻头井底重量、扭矩,还可提供井底温度、地层放射性、
Logging While Drilling (Logging During Drilling) has been continuously evolving due to the actual need to drill a deviated well under conditions of drilling and land complex offshore platforms. In the 1950s, cable logging tools were developed. Up to now, such instruments have been improved and applied. It can only measure well inclination, azimuth, temperature, and developed from downhole timed photographic record to ground digital record and computer control. Then, a cable-free, logging-by-turn tool was developed and a measurement system for transmitting signals with mud was studied. Currently understand: the United States engaged in drilling while drilling research and production companies Oriental slant company, Schlumberger - analyst company, Ji Hatt company, science controlled drilling company. LWDs with mud telemetry systems are already being commercialized and their services are increasingly being augmented. In addition to providing well orientation, horizontal drift (borehole inclination), bottom hole weight, and torque, bottomhole temperature can also be provided , Stratum radioactivity,
