录井工程参数采集系统无线化技术研究

Wireless technology discussion on the system of mud logging engineering parameter acquisition

综合录井仪的数据采集一般采用集中式或现场总线式布线,由于井场环境复杂,加之布线工作量大且繁琐,因而实现采集系统的无线化应是一个发展方向。以工程参数录井为例,分别从无线化通信技术、无线化节点设计、无线化节点联网等方面进行了探讨;分析了实现井场工程参数采集系统无线化需要解决的井场干扰、能源供给以及采集仪器小型化设计方面的问题;介绍了实现井场采集仪器无线化的研究重点和发展趋势,提出了实现无线化的设计思路,认为随着有关问题的解决以及相关支撑技术的发展,首先可以实现综合录井工程参数采集系统的无线化。

The data acquisition of comprehensive logging units commonly uses centralized or wellsite bus arrangement of the wires. As the site environment is complex and the arrangement of wires is heavy and tedious, it should be a developing direction to realize wireless for the acquisition system. Take an example of engineering parameters, the paper discussed wireless communication technology, node design and node internet respectively, analyzed the problems needed to be solved during realizing site engineering parameter acquisition wireless, such as site interference, power supply and miniaturization design for acquisition instruments, introduced the researching focus and developing trend for realizing wireless of site acquisition instruments, and set forth the designing thought of wireless. The author considered that the wireless for comprehensive mud logging engineering parameter acquisition can be first realized with solving the related problems and the developing of the related supporting technology.
