PNN剩余油饱和度测井技术在延长油田的应用

Application of PNN Residual Oil Saturation Logging Technology in Yanchang Oilfield

脉冲中子-中子(PNN)测井是利用直接测量热中子通量进而计算剩余油饱和度的测井技术。文中介绍了该技术的测井原理及其解释方法,并列举该技术在延长油田的应用情况。结合目前使用的情况,对今后的研究方向提出建议。

Pulsed neutron-neutron（PNN） logging is a kind of logging technology to calculate residual oil saturation through direct measurement of thermal neutron flux. In this paper, the principle and the interpretation method of the logging technique were introduced, and application of the logging technique in Yanchang oilfield was discussed. Combined with the present use situation, some suggestions for future research direction of the logging technique were put forward.
