摘要:

这项工作的目的是使用一系列机器学习算法和数据增强和修改方法来预测所研究的沿海地区具有碳氢化合物收集特性的岩层的传播概率。该研究发展了机器学习的方向,其中对井数据和空间属性进行训练。克服这个方向的局限性的方法示出,两种方法-增加和修改的井数据样本:主轴和反向校准。考虑到沿海地区条件下地震资料解释的困难,所提出的方法是一种能够与地质和地球物理数据的整体一起工作的工具,从159维空间属性中提取知识,进行相展布预测,预测质量合格--储层级别F1测度平均为0.798,用于“钻井”评价不同地质条件的结果。结果表明,在实施的技术堆栈中一致应用所提出的增强方法,相对于原始数据集,将储层预测的质量提高了1.56倍。

英文摘要:

The aim of this work was to predict the probability of the spread of rock formations with hydrocarbon-collecting properties in the studied coastal area using a stack of machine learning algorithms and data augmentation and modification methods. This research develops the direction of machine learning where training is conducted on well data and spatial attributes. Methods for overcoming the limitations of this direction are shown, two methods - augmentation and modification of the well data sample: Spindle and Revers-Calibration. Considering the difficulties for seismic data interpretation in coastal area conditions, the proposed approach is a tool which is able to work with the whole totality of geological and geophysical data, extract the knowledge from 159-dimensional space spatial attributes and make facies spreading prediction with acceptable quality - F1 measure for reservoir class 0.798 on average for evaluation of "drilling" results of different geological conditions. It was shown that consistent application of the proposed augmentation methods in the implemented technology stack improves the quality of reservoir prediction by a factor of 1.56 relative to the original dataset.
