Method and device for modeling reservoir physical property parameter

Abstract

The invention discloses a method and a device for modeling a reservoir physical property parameter. The method comprises the following steps: firstly, constructing a three-dimensional sedimentary facies model of a reservoir, and establishing a three-dimensional reservoir petrophysical facies model under the restriction of the three-dimensional sedimentary facies model; secondly, establishing a three-dimensional reservoir physical property parameter model under the restriction of the three-dimensional reservoir petrophysical facies model. Compared with the prior art, the method and the device have the advantages that when a reservoir petrophysical property parameter model is constructed, sedimentary facies restriction is considered, and the influence of reservoir petrophysical facies is also considered, so that a modeling result can reflect a combined action of a reservoir sedimentation action, a diagenesis action and a later-stage construction action, thereby improving the modeling accuracy of the reservoir physical property parameter.

Description

technical field [0001] The present application relates to the field of petroleum exploration, and more specifically, to a method and device for modeling reservoir physical property parameters. Background technique [0002] When describing the reservoir, the core is to establish a reservoir physical parameter model. Reservoir physical parameter modeling can not only provide prior physical property information for exploration, but also provide initial physical property model for reservoir development simulation. The address model finally established is used to represent the distribution of storage address feature space and various attribute parameters. The three-dimensional data volume can be displayed as a spatial image through the output of the software. [0003] The current modeling method is to establish a geological model under the constraints of sedimentary facies. The structural model, sedimentary facies model and physical parameter model should be established in seque...

Problems solved by technology

[0003] The current modeling method is to establish a geological model under the constraints of sedimentary facies. The structural model, sedimentary facies model and physical parameter model should be established in sequence. Since the influence of reservoir physical relative modeling is not considered in the prior art, the established reservoir The layer physical property parameter model has low accuracy in describing the reservoir
