Abstract

The invention discloses a device for interpreting fractured reservoir prediction. By the device, the seismic wave nonlinear dynamics properties, such as redundant dictionaries and chaos, of a fractured reservoir are computed; and by adopting a high order accumulation processing technology, non-gaussian seismic signals of the fractured reservoir can be processed and computed, so that the density aggregation projection analysis of acquired seismic attributes representing the fractured reservoir can be realized. According to the device, a computer is used for assisting in the completion of the interpretation of the fractured reservoir, so that favorable reservoir prediction files are formed. The device has the advantages of high computational efficiency, objective and accurate fractured reservoir interpretation results, and the like; and by the device, the accuracy of the reservoir interpretation and the seismic interpretation efficiency can be effectively improved.

Description

technical field

[0001] The invention relates to the prediction and interpretation technology of ground fractured reservoirs, in particular to an automatic prediction and interpretation device for fractured reservoirs based on three-dimensional seismic data volumes. Background technique

[0002] The geological conditions of fractured oil reservoirs are very complex, which is mainly reflected in the following aspects: complex structure and fault systems, fractured carbonate reservoirs in the Bohai Bay Basin generally experience multi-stage tectonic movements, and their structural insides are extremely complex. The burial depth and low resolution of seismic data make structural interpretation very difficult; there are many types of reservoir spaces, including fractures, pores, dissolved pores and caves, and more than a dozen types of reservoir spaces. The distribution of fractures is extremely heterogeneous, and wells It is more difficult to understand the degree of reservoir d...
