储层相对稳定性是以一定的表征尺度为基础 ,储层参数在给定的空间 (或时间 )变程内的变化量是变程的函数。这是沉积储层所普遍具有的特征。储层相对稳定性提供了一种综合测井、地震、地质资料进行定量储层模拟的新途径 ,它能同时在一定程度上保持井的高垂向分辨率和地震的高横向分辨率信息 ,从而提高模型的表征精度。将储层相对稳定性作为储层横向变化的约束条件 ,并与地震随机反演相结合用于定量储层模拟研究 ,结果表明该方法能显著提高储层横向预测的精度和外推合理性。
The relative stability of a reservoir is based on a certain characterization scale. The variation of reservoir parameters within a given spatial (or temporal) range is a function of the range. This is a common feature of sedimentary reservoirs. The relative stability of the reservoir provides a new way of quantitative reservoir simulation based on comprehensive logging, seismic and geological data. It can maintain the high vertical resolution of the well and the high lateral resolution of the seismic data at the same time, Thus improving the characterization accuracy of the model. The relative stability of reservoirs is taken as the constraint of lateral variation of reservoirs, and combined with random seismic inversion for quantitative reservoir simulation. The results show that this method can significantly improve the accuracy and extrapolation rationality of reservoir lateral prediction.
