目前,由于储层类型的多样化,出现了非均质性很强的特点。说明油田已经进入了高含水期。现将应用概率图法,对S油层进行分类,并对水淹机理进行细致研究,从岩心电阻率以及含水饱和度的规律可知其内在的辩护规律。结合储层含钙情况,应用导电理论,建立了适宜的电阻率模型。在实际应用中,取得了很好的效果。经过检验,水淹层符合达标率已经超过了80%,完全满足剩余油以及水淹层的评价需要。
At present, due to the diversification of reservoir types, there is a strong heterogeneity. Oilfield has entered a high water cut period. The probability map method will be used to classify the S reservoirs and study the flooding mechanism carefully. From the laws of core resistivity and water saturation, we can see its inherent law of defense. According to the situation of calcium in the reservoir, a suitable resistivity model is established by using the conductive theory. In practical applications, has achieved good results. After testing, the water flooding layer meets the compliance rate has exceeded 80%, fully meet the remaining oil and flooded layer evaluation needs.
