摘要/Abstract

摘要：

鄂尔多斯盆地旬邑探区延长组开发潜力较大，储层特征的定量评价对准确预测开发效果具有指导意义。选取延长组6段（长6）和延长组8段（长8）储层典型岩心进行实验分析，核磁共振实验结果显示长6和长8储层孔喉分布特征较为单一，不进行离心实验的情况下可利用核磁共振渗透率和T₂几何平均值计算可动流体百分数。恒速压汞实验结果表明，孔隙比喉道发育均匀，未开展其他实验的情况下可利用恒速压汞实验计算孔隙度。通过建立核磁共振和恒速压汞耦合求取完整孔喉半径分布的方法，确定了旬邑探区延长组长6和长8储层的表面弛豫率为0.15 μm/ms。核磁共振孔喉半径分布的计算结果显示，长6储层孔喉半径分布范围为0.01~433.10 μm，长8储层孔喉半径分布范围为0.01~403.91 μm，长6储层孔喉发育比长8储层均匀。通过定义拟粒间孔和拟溶蚀孔，拟溶蚀孔绝对体积占比揭示，长8储层渗流能力强于长6储层。建立了"拟溶蚀孔+含油饱和度"方法预测开发效果，分析认为拟溶蚀孔对试油产量的影响更大，进一步揭示了旬邑探区长8储层整体开发效果好于长6储层。

Abstract:

Yanchang Formation in Xunyi exploration area of Ordos Basin has great development potential, and the quantitative evaluation of reservoir characteristics has a certain guiding significance for accurately predicting development performance. Typical cores of Chang 6 and Chang 8 reservoirs are selected for experiments. Nuclear Magnetic Resonance (NMR)results indicate that both Chang 6 and Chang 8 reservoirs show the relatively single distribution characteristics of pore throat; the percentage of movable fluid can be calculated using the NMR permeability or T₂ geometric mean without doing centrifugation experiments; the constant-rate mercury injection experiment results show the more uniform pore development than throat development, and the porosity can be calculated by constant-rate mercury injection experiment in case of no other experiments. This study establishes a method for obtaining complete pore throat radius distribution by the coupling between NMR and constant-rate mercury injection experiment; the surface relaxivity of Chang 6 and Chang 8 reservoirs of Yanchang Formation in Xunyi exploration area is determined as 0.15 μm/ms. The NMR experiment shows that the pore radius distribution in Chang 6 and Chang 8 reservoir is within the range of 0.01-433.10 μm and 0.01-403.91 μm respectively, indicating the more homogeneous pore throat development in the latter. Pseudo intergranular pores and pseudo dissolution pores are defined, and the absolute volume ratio of pseudo dissolution pores indicate Chang 8 reservoir has greater seepage capacity than Chang 6 reservoir. Moreover, this study sets up the method to predict development performance by "pseudo dissolution pores + oil saturation", and the analysis results show pseudo dissolution pores have a greater impact on the oil test production, thus achieving the prediction of oil well production. The further study reveals that on the whole, Chang 8 reservoir presents better development than Chang 6 reservoir in Xunyi exploration area.

Key words: Ordos Basin, nuclear magnetic resonance, constant-rate mercury injection, surface relaxivity, pseudo intergranular pores, pseudo dissolution pores, development performance prediction
