井下温度 meaning in English
dht
downhole temperature
Examples
- For a complex well logging , telemetry tools which are used to uplink digital data of the memory tools to surface instructions may benefit significantly detailed monitoring and controlling the work of the well
在测井行业中，遥传仪器对精确的监测和控制石油井的运作有显著作用，它的功能是将井下温度、压力等参数的测量数据传递到地面仪器。 - At present , temperature logging is one must in production logging , but most temperature logs are only used to do qualitative analysis to discover the abnormal under wells and some other alike , which is a great waste of the logging information sources for the low level use of the logs
目前，温度测井是必备的生产测井之一，但大多数的温度测井信息主要用来定性分析井下异常，对井下温度信息的利用程度很低，这在一定程度上是一种信息资源浪费。 - On the basis of describing the situation of current logging technology and considering the atrocious environment and the superiority of video imaging well - logging , the logging system consists of hardware and software sub - system in this paper . according to the objective condition of logging , the design of hardware has taken special treatments : high - temperature - proof protection with particular equipment for the whole circuit , video collection with ccd , temperature signal gathering by pt resistance and v / f transform , depth measurement through photoelectric encoder and jitter elimination circuit
在系统的硬件设计中，针对油田测井的客观环境，进行了特殊处理：对整体测量电路采用特种装备进行耐高温保护；对井下的视频信号采用ccd摄像头进行采集；对井下温度信号利用铂电阻和v f变换实现采集；对深度信号采用光电码盘及去抖电路进行精确测量。
