Abstract

The invention discloses a characterization method of a fractured reservoir and an apparatus thereof. The method comprises the following steps: reading one or more attribute data of one or more point related to the fractured reservoir; according to the one or more attribute data of the one or more point, establishing one or more cuboids one to one corresponding to the one or more point, wherein one or more of a plurality of surfaces, a length, a width, a height, an azimuth angle and an angle of inclination indicates the one or more attribute data respectively. Through the technical scheme, the plurality of surfaces, the length, the width, the height, the azimuth angle and the angle of inclination of the cuboid can be used to characterize the each attribute of the fractured reservoir. Fracture reservoir attribute information, geology construction information and reservoir rock physics information are integrated in one map to characterize. Through the attribute, adjustment of a valve value is displayed so as to reach a purpose of multi-attribute integration intersection. The fractured reservoir with a high quality is directly delineated. A direct basis is provided for well position determination, gas reservoir description and reservoir identification.

Description

technical field

[0001] The invention relates to the field of seismic exploration, in particular to a method and device for characterizing fractured reservoirs. Background technique

[0002] At present, more than half of the world's oil and gas are produced from natural fractured oil and gas reservoirs. In the 21st century, fractured oil and gas reservoirs will be one of the main fields for increasing oil and gas reserves and production. In my country, the distribution of fractured oil and gas reservoirs is also very wide, occupying a very important position in my country's oil and gas production. However, due to the low porosity, strong heterogeneity and complex distribution of fractures, fractured oil and gas reservoirs are essentially different from porous oil and gas reservoirs, making the development of fractured oil and gas reservoirs a recognized problem in the world petroleum industry today. With the continuous deepening of research on fractured oil and gas reservoi...
