摘要
通过对水淹层地球化学资料的分析,总结出了不同程度水淹层的地球化学特征,提出了利用地球化学资料从定性识别到定量评价的水淹层评价思路,建立了水淹层水淹程度定性识别方法、剩余油饱和度和含水率定量评价模型。对储层物理性质、岩性、流体性质、水淹程度不同的108口井529层水淹层进行了评价,剩余油饱和度与经校正后的密闭取芯井岩芯分析剩余油饱和度非常接近,水淹级别、含水率与单层试油结果一致。证明利用地球化学资料评价水淹层方法是可行的,结果是可靠的,该方法有很好的推广应用前景。
The geochemical characteristics of the waterflooded zones with different degrees are summarized through analyzing. The waterflooded zone evaluation idea from qualitative identification to geochemical information is presented, and the qualitative identification method of the quantitative evaluation model of the remaining oil saturation and the water cut are quantitative evaluation with waterflooded degree and the also established. The 529 waterflooded zones in 108 wells with the different reservoir physical properties, lithology, fluid characteristics and waterflooded degrees are evaluated. The results show that the remaining oil saturation is much closed to the sealing core drilling analysis after correction and the waterflooded degree oil, which implies that the waterllooded zone evaluation method has good application perspective. and water cut is accordance with signal layer test is feasible and the result is credible. The method
