基于岩石物理转换模型的苏里格致密砂岩储层测井评价与产能预测
|
摘要
苏里格地区致密砂岩储层勘探开发难度很大,测井解释遇到了储层参数计算和产能预测不准确的问题.本文针对这些难点,基于已有的转换模型,推导并验证了T_2-I和T_2-K_r转换模型,提出了采用转换模型应用于测井综合解释和产能预测的方法.基于实验数据设定孔径大于1μm的孔隙为大孔,中孔孔径在1μm和0.03μm之间,小孔孔径为0.03μm以下.并建立了不同孔径范围模型中关键参数α与核磁参数T_(2lm)的关系,这为转换模型在测井解释中的应用提供了必要条件.本文在苏里格西区分别应用T_2-I和T_2-K_r转换模型求取含水饱和度和相对渗透率曲线,并进行产能预测,处理结果显示该方法具有很好的应用效果.
The exploration and development of tight sandstone reservoirs in the Sulige area are very difficult.Log interpretation has encountered inaccuracies in reservoir parameters calculation and productivity prediction.In view of these difficulties,the T_2-I and T_2-K_r models were derived and validated based on the existing transformation models.We also put forward a method of applying the transformation models to comprehensive logging interpretation and productivity prediction.Based on the experimental results,the transformation process needs to be divided into sections,we set the pore radius which greater than 1μm as the macropore,the mesopore ranged from 1μm and 0.03μm,and the micropore was set as the pore radius below 0.03μm.And we established the relationship between the key parameterαand NMR(Nuclear Magnetic Resonance)logging parameter T_(2lm)in different sections of pore size,which provided the necessary conditions for the application of the transformation models in logging interpretation.Using the T_2-I and T_2-K_r models in the western Sulige area,the water saturation and relative permeability curves wereobtained and the productivity prediction was carried out.The conclusions of comprehensive logging interpretation showed that our method achieved good results.
