新世纪的测井技术--网络测井及其技术体系初探

测井技术正面临着新的变革。基于互联网技术的第五代测井数据采集系统以快速、可靠、信息共享为主要特征,正在形成之中,相应的井下仪器提供的观测信息应该适合网络技术和油藏实时解决方案的要求。一些有深刻物理背景的、能够快速提供地层流体和地质信息的方法,在网络测井中一定会得到进一步重视和发展。核磁共振、阵列感应、声电成像、交叉偶极声波、脉冲中子、过套管电阻率以及电缆地层测试和井壁取心等方法,为勘探和开发阶段的油藏解决方案提供丰富的岩石物理和油气信息,将成为新一代测井技术中不可缺少的重要方法。第一次正式提出网络测井新概念,初步探讨新一代测井技术体系,包括基于互联网的测井数据采集、流体识别和储层评价系统。较为详细地讨论了以核磁共振为核心的裸眼井油气识别和评价技术。

Well Logging Technology for The New Century: Network-based Logging Technology

Well logging technology is facing a new revolution. The fifth generation of the logging acquisition system which is based on the Internet technique is on the way. The key features of the new system are fast, reliable, and information sharing by multi-users. The measurements from downhole tools have to meet the requirements for realtime reservoir solutions. Platform eXpress, NMR, array induction, electric and acoustic imaging, cross dipole acoustic, pulsed neutron, through casing resistivity, module formation tester and coring tool may become very important portion in the new technology system. In this paper, the concept and main features of the internet-based logging system are, for the first time, introduced. Downhole measurements at the imaging logging time are summarized and analyzed in details. The authors believe that NMR will play an important role in the new generation of logging technology.
