Embodiment Construction

[0037] The present invention will be further described below in conjunction with the accompanying drawings.

[0038] This method of efficient seismic interpretation using multi-window continuous sections first performs fault interpretation and then horizon interpretation, as follows:

[0039] 1. Fault explanation:

[0040] 1) Guided by the stress field before and during the interpretation work, analyze the plane structure pattern on the time slice of the coherent body, and judge the nature of the fault through the strike, so as to determine the corresponding section structure pattern on the section, while taking into account the fault combination;

[0041] 2) In the first interpretation tract section (see figure 1 ) to observe the dip angle, vertical scale, shape and combination with adjacent faults of the target fault;

[0042] 3) Open the adjacent Next Interpretation Section (see figure 2 ), and then inspect and compare the above contents, the purpose is to exclude the ...

Abstract

The invention relates to an efficient seismic interpretation method through multi-window continuous sections. The method includes 1, fault interpretation, namely analyzing a planar structural pattern on coherence time slices, determining the corresponded section structural pattern on the sections, and considering the fault combination, observing the situation of a target fault on a first interpretation channel section, opening the section of the next interpretation channel, comparing the content, opening the isochronal coherence slices at the head and tail of the fault, confirming the connection relationship of the target fault and an adjacent fault, controlling the direction of the fault, and implementing the fault interpretation on the section; 2, horizon interpretation, namely avoiding the fault and establishing a backbone section on a time slice adjacent to a target horizon, interpreting the backbone section, opening the interpretation channel sections of two adjacent main lines, opening the interpretation channel sections of two adjacent cross lines at one end, and repeating the steps until the horizon interpretation of the region between the two main lines is completed. By the aid of the method, the accuracy of seismic data interpretation and interpretation efficiency can be improved.

Description

technical field [0001] The invention relates to seismic interpretation work in the field of oil and gas exploration, in particular to a method for efficiently performing seismic interpretation by using multi-window continuous sections. Background technique [0002] Seismic data interpretation plays a very important role in seismic exploration. Whether the interpretation results are correct or not is directly related to major strategic issues such as the discovery of oil and gas reservoirs, evaluation of basins, and selection of oil and gas exploration directions. It is of great significance to improve the accuracy of seismic data interpretation and improve the interpretation efficiency. Currently commonly used seismic interpretation techniques include dynamic detection methods, 3D visualization techniques, and rapid 3D fault and horizon interpretation methods based on plane navigation. [0003] 1. The dynamic detection method can observe the spatial form of complex geologic...
