【摘要】：在油气勘探开发过程中,特别是在大位移定向井、鱼骨水平井、深井、超深井施工中,综合录井技术发挥着日益重要的作用。作为综合录井仪的核心部分,数据采集系统在钻井施工中,能够连续采集地质、工程、钻井液和气测数据。但是目前的状况是国内外综合录井仪种类繁多,其数据采集系统功能大致相同,而采集硬件、数据处理、传输和数据类型差异较大,不同的采集硬件需要相应的软件支持。为了满足标准化要求,规范数据采集格式,在装备制造和升级中减少投资,开展了新型综合录井数据采集系统研究。本文剖析了国内主流的综合录井仪数据采集系统的基本原理和架构,细致研究了数据采集系统各模块的功能实现,在现有功能上进一步完善,结合钻井现场录井传感器信号采集和传输的需求,提出了通用型综合录井数据采集接口技术,并予以研究、设计和应用,集成了RS485总线技术、CAN总线传输技术和无线网络传输技术,并开发了配套的传感器信号采集接口软件和色谱数据接口软件,可实现WITS标准数据输出。整套系统完成了实验室的整体测试和钻井现场测试。实验结果表明新型的综合录井采集系统可以对工程参数、钻井液参数、其他参数等数字量和模拟量信号完成高精度采集和处理,不仅提高了数据质量,而且能够兼容取代陈旧的采集硬件系统,在装备改造方面节约了大量投资,解决了仪器种类繁杂、培训难度大、后勤保障困难等问题。在国内多个油田进行了应用,在钻井工程应用中能够准确监测钻井工况,及时发现钻井参数异常、地层压力监测、优化钻井参数,在提高钻井时效,节约勘探开发投资方面取得了很好效果,具有广阔的推广应用前景。
[Abstract]:In the process of oil and gas exploration and development, especially in long reach directional wells, fish bone horizontal wells, deep wells, ultra-deep wells, comprehensive logging technology plays an increasingly important role. As the core part of the integrated logging instrument, the data acquisition system can continuously collect geological, engineering, drilling fluid and gas data during drilling operation. However, the current situation is that there are many kinds of comprehensive logging instruments at home and abroad, and the functions of the data acquisition system are roughly the same, and the data acquisition hardware, data processing, transmission and data types are quite different, and different acquisition hardware needs the corresponding software support. In order to meet the requirements of standardization, standardize data acquisition format and reduce investment in equipment manufacturing and upgrading, a new comprehensive mud logging data acquisition system was studied. In this paper, the basic principle and structure of the mainstream data acquisition system of integrated logging instrument are analyzed, and the functional realization of each module of the data acquisition system is studied in detail, and the existing functions are further improved. Combined with the demand of signal acquisition and transmission of mud logging sensor in drilling field, a general integrated logging data acquisition interface technology is put forward and studied, designed and applied. The RS485 bus technology is integrated with the can bus transmission technology and the wireless network transmission technology, and a complete set of sensor signal acquisition interface software and chromatographic data interface software are developed, which can realize the WITS standard data output. The whole system has completed the whole laboratory test and the drilling field test. The experimental results show that the new integrated logging acquisition system can acquire and process the digital and analog signals of engineering parameters, drilling fluid parameters and other parameters with high precision, which not only improves the data quality, but also improves the data quality. Moreover, it can replace the old collection hardware system, save a lot of investment in the equipment reform, and solve the problems such as the variety of instruments, the difficulty of training, the difficulty of logistics support, and so on. It has been applied in many oil fields in China. It can accurately monitor drilling conditions, find abnormal drilling parameters, monitor formation pressure and optimize drilling parameters in order to improve drilling efficiency. The result of saving the investment in exploration and development is very good, and it has a broad prospect of popularization and application.
