摘要:
核磁共振測井技術作為同時評價儲層孔隙特征和流體識別的方法,具有獨特的優越性。在實際應用中,井下居中型核磁共振測井儀探測深度受到井眼尺寸的影響,尤其當井眼鉆井液電導率較高時,儀器將無法采集到可靠的有用信號。井下偏心核磁共振測井儀可有效解決上述問題。介紹了一種新型的井下偏心核磁共振測井儀探測器結構,通過數值模擬技術對探測器結構進行優化,并完成了實物制作。通過對探測器加工工藝探索,有效降低了天線渦流損耗和振鈴的影響,并成功在實驗水箱中獲取到了核磁共振回波信號。
Abstract:
NMR logging technology has unique advantages as the only method to simultaneously evaluate reservoir pore characteristics and fluid identification. In practical applications, the radial investigation depth of centered downhole nuclear magnetic logging tools is affected by the size of the wellbore, especially when the conductivity of the wellbore mud is high, the probe will not be able to receive reliable useful signals. Eccentric downhole NMR logging tools can effectively solve the above problems. This paper introduces a new type of probe structure for eccentric downhole NMR logging tools. The structure of the probe was optimized by numerical simulation technology and the physical production was completed. By exploring the processing technology of the probe, the effect of eddy current loss and ringing of the antenna are effectively reduced, and the nuclear magnetic resonance echo signals are successfully obtained in the water tank.
