国外七十年代测井技术水平与趋向一、系列化 1.根据不同的地质特点,选择不同的测井仪器系列。为了提高测井速度和在井场直接进行数字处理、取得测井中间参数、确定含油井段,目前采用3～6种测井仪器进行组合,一次下井测得多个参数。井下仪器采用聚焦和贴井壁补偿技术,以消除井眼影响。 2.测井装备多样化和现代化。为了适应不同地区的不同条件,有拖撬以及用于沼泽、沙漠、浅海、海滩地区的测井装备,出现了海洋测井船和用直升飞机运载测井装备等。
Seventies abroad, the level of logging technology and trends First, serialization 1. According to different geological features, choose a different logging instrument series. In order to improve the logging speed and digital processing directly in the wellsite, the logging intermediate parameters are obtained and the oil-bearing intervals are determined. At present, 3-6 logging tools are used for combination and multiple parameters are measured once. Downhole instruments use focusing and post wall compensation techniques to eliminate borehole effects. Logging equipment diversification and modernization. In order to adapt to the different conditions in different regions, there are towing and logging equipment used in marsh, desert, shallow sea and beach areas, and marine logging boats and helicopter-borne logging equipment are emerging.
