井口直立深度记录器的设计及其应用前景

The design of vertical depth recorder in well head

电缆做记号时,所依赖的深度数据来自装在地滑轮上的编码器。这种标记方法会产生好多问题,首先燃油用量很大,其次记录的误差又很大。通过对该井口直立深度记录器的组成部件、技术关键、性能指标、使用方法等方面的介绍,让大家了解了该记录器的特点。该记录器达到了提高记录准确率、节省燃料油、降低劳动强度等目的,建议在各油田电缆作业时推广应用。

When marking the cable, the key data of the depth can be acquired from the encoder fixed on thehay pulley. There are many concomitant problems when using this method such as much morewasting of the fuel and the bigger deviation of recording. The advantages of the vertical depth log-ger can be understood by introducing the composition part of wellhead vertical depth logger, thekey technology, the performance indicators and the methods. The accuracy of recording can be im-proved and the fuel oil can be saved by using the logger.
