摘　　要：随着钻探深度的不断增加,异常高压储集层为录井解释评价带来较大挑战,尤其在储集层含水性判别方法上亟需寻找新的突破方向。在录井解释评价中发现,核磁共振技术与显微荧光薄片技术在含水性评价领域具有一定的指导作用,通过实验研究总结了核磁共振流体性质评价方法、显微荧光含水性判别方法,在储集层流体性质评价方面起到了很好的指导作用,避免了异常高压储集层的影响因素,并在核磁共振与显微荧光薄片技术融合的基础上创建了核磁-显微荧光三维立体评价模型。2020年在准噶尔盆地异常高压储集层勘探中,核磁-显微荧光三维立体评价模型应用效果显著,含水性判别符合率达到85.75%,为异常高压储集层含水性判别提供了有力的技术支撑,拓宽了录井技术在储集层含水性识别领域的发展思路。With the increase of drilling depth,abnormal high pressure reservoir brings great challenges to mud logging interpretation and evaluation.In particular,it is urgent to find a new breakthrough direction in the discriminant method of reservoir aquosity.In mud logging interpretation and evaluation,it is found NMR technology and microfluorescence thin section technology play a guiding role in the water evaluation field.Through experimental research,this paper concludes that the NMR fluid property evaluation and microfluorescence water discriminant methods play a good guiding role in the reservoir fluid property evaluation and avoid the influence factors of abnormal high pressure reservoir.Based on the fusion of NMR and microfluorescence thin section technologies,the NMR-microfluorescence 3D evaluation model is established.In 2020,in the exploration of abnormal high pressure reservoir in Junggar Basin,the application effect of NMR-microfluorescence 3D evaluation model is remarkable,and the coincidence rate of water discrimination reaches 85.75%,which provides strong technical support for water discrimination of abnormal high pressure reservoir and widens the development idea of mud logging technology in the field of reservoir aquosity identification.
