摘　　要：海上油气钻井是一项高投入、高风险和高技术水平的隐蔽性地下工程,在钻井各个阶段均存在不同程度、形式各异的风险,尤其是在进行深层、深水、高温高压和复杂地质条件下钻井时,由于储层埋藏深、地质条件复杂,潜在风险更为突出,需要综合运用地质、地震、测井、岩石力学、钻井工程、智能科学、计算机等多种学科。从工程技术角度出发,深入研究海上智能钻井的关键技术,为智能钻井工具研制、配套钻参优化软件系统研发奠定了技术基础。近年来随着钻井的智能化发展,对井底数据的精确性和实时性提出了越来越高的要求。目前,井底数据传输依赖传统的MWD模式,传输速度为8~15 bits,传输数据容量低,无法满足现场作业实时监测的需求,也无法应对智能井下数据传输分析需求。针对上述问题,文章从井下工程参数实时监测技术及工具入手,实现关键数据从计算获得到实时监测,通过数据优选和压缩技术,再结合LWD/MWD或智能钻杆进行井下数据低滞后传输,从而实现井下数据的实时监测,为监测井下状况和智能化钻井的实现提供了保障。Offshore oil and gas drilling is a concealed underground project with high investment,high risk,and high technological level.There are varying degrees and forms of risks in each stage of drilling.Especially when drilling in deep formation and deep water under high temperature,high pressure and complex geological conditions,due to the deep burial of reservoirs and complex geological conditions,potential risks are more prominent.It is necessary to comprehensively apply various disciplines such as petroleum geology,seismic technology,logging technology,rock mechanics,drilling engineering,intelligent science,computer science,etc.From the perspective of engineering technology,in-depth research on the key technologies and methods of offshore intelligent drilling can lay a technical foundation for the development of intelligent drilling tools and supporting drilling parameter optimization software systems.In recent years,with the development of intelligent drilling,there has been an increasing demand for the accuracy and real-time performance of downhole data.At present,the transmission of downhole data relies on the traditional MWD mode,with a transmission speed of 8-15 bits and a low data transmission capacity,which cannot meet the real-time monitoring needs of on-site operations,nor can it meet the requirements of intelligent downhole data transmission and analysis.In response to the above issues,it is proposed to start with real-time monitoring technology and tools for downhole engineering parameters,to achieve key data from calculation to real-time monitoring.Through data optimization and compression technology,combined with LWD/MWD or intelligent drill rods for low latency transmission of downhole data,real-time monitoring of downhole data can be achieved,providing a guarantee for insight into downhole conditions and the realization of intelligent drilling during the drilling process.
