摘要:
为了定量评价实验室测量的密闭取心饱和度与地层条件下饱和度的差异,寻求适合珠江口盆地(西部)高泥质含量储层密闭取心饱和度的校正方法,本文分析了造成密闭取心饱和度损失的主要因素,认为常规的密闭取心饱和度校正方法未考虑高黏土含量的影响,这是造成实验室分析的含水饱和度偏高的一个重要原因。在常规密闭取心饱和度校正方法的基础上,利用核磁资料法与常规物性法对实验室测量的原始饱和度结果进行黏土水校正,消除高泥质含量对实验结果的影响,得到了一种改进的密闭取心饱和度校正方法。利用本文方法对该地区X4井的密闭取心饱和度进行了校正,结果表明校正后岩心饱和度与核磁测井饱和度吻合很好,可使密闭取心含油饱和度平均增加约7%。
Abstract:
In order to quantitatively evaluate the difference between the saturation of confined cores measured in the laboratory and the in-situ saturation, a correction method suitable for the closed coring saturation of high shaly content reservoirs in the western Pearl River Mouth Basin is required. The main factors causing the saturation loss of sealed coring were analyzed in this paper, and it is considered that the conventional closed coring saturation correction methods fail to take into account the effect of high clay content, which is a major reason for the high water saturation in laboratory analysis. Based on the saturation correction method for conventional closed coring, the nuclear saturation data method and the conventional physical properties method were used to conduct the clay-water correction of the indoors measured original saturation, so as to eliminate the effect of high shaly content on the experimental results, hence obtaining an improved closed coring saturation correction method. This method was used to correct the sealed coring saturation of Well X4 in this area. The results show that the corrected core saturation is in good agreement with the NMR logging saturation, and the oil saturation of closed coring can be increased by about 7% on average.
