Abstract

The invention provides a reservoir prediction method and device based on mixosedimentite. The method comprises the following steps of acquiring pre-stack seismic trace gather data received by a plurality of detectors forming different angles with excitation points, superposing the pre-stack seismic trace gather data of each angle to generate sub-offset superposition trace gather data, synthesizinga seismic record according to the logging data and the pre-stack seismic trace gather data, according to the seismic record, using a pre-stack seismic inversion method to generate a reservoir sensitivity factor of the mixosedimentite, and predicting the distribution condition of the mixosedimentite reservoir in the target area according to the reservoir sensitive factor. According to the method,the distribution condition of the mixosedimentite reservoir can be accurately predicted.

Description

technical field [0001] The invention relates to petroleum exploration technology, especially to the field of geophysical exploration, in particular to a diamictite-based reservoir prediction method and device. Background technique [0002] In some areas (such as the Xiaganchaigou Formation in the Yingxi area of ​​the Qaidam Basin), the reservoirs are mostly saline lacustrine carbonate deposits, and the reservoirs are mostly mixed lithologies such as salt rock, mudstone, and lime dolomite. , the reservoir rock composition includes: clay, gypsum-salt rock, sandy, limestone, dolomite, etc. The main lithological component of the reservoir is limestone, which generally contains muddy and sandy components, and some of them contain Gypsum-salt rock has complex and diverse lithological components, and exhibits the characteristics of mutual mixing, strong heterogeneity, and difficult reservoir prediction. [0003] At present, there are two common types of reservoir prediction techno...
