Abstract

The invention provides a reservoir prediction method and a reservoir prediction device. The reservoir prediction method comprises the steps of: acquiring three first attribute data volumes of a sampling point relevant to a reservoir, and performing normalization calculation on the three first attribute data volumes respectively to obtain three second attribute data volumes; determining reservoir threshold value ranges by utilizing the three second attribute data volumes respectively to obtain three threshold value ranges; performing data reconstruction by utilizing the three threshold value ranges to obtain three reconstructed data volumes; performing color fusion processing on the three reconstructed data volumes to obtain a color fusion data volume; and predicting reservoir types according to the color fusion data volume. The reservoir prediction method and the reservoir prediction device can achieve prediction of various kinds of reservoir types, and make the distribution condition of different reservoir types more convenient and intuitive by separating reservoir of different types through different colors, thereby increasing the efficiency of oil and gas exploration.

Description

technical field [0001] The invention relates to the technical field of oil and gas exploration, in particular to a reservoir prediction method and device. Background technique [0002] In the field of geophysical exploration, after acquiring seismic data through conventional methods, it is necessary to interpret the seismic data, and generally carry out the corresponding reservoir prediction and interpretation process. In the process of reservoir prediction and interpretation, it is necessary to analyze the relevant logging data, and carry out relevant attribute extraction and inversion calculations on the seismic data, and then use the original seismic data, logging data, extracted or inverted attribute data Qualitative and quantitative analysis are performed on each other to identify possible reservoir development areas and intervals, so as to complete the reservoir prediction work. [0003] Reservoirs have certain physical characteristics, and the types of reservoirs als...
