Abstract

The invention discloses an interval velocity model building method under complicated geological conditions, firstly solves the problem of time dimension fitting under complicated terrain conditions and also solves the problems of interval velocity filling and speed modeling on the basis of the solving of the problem of time dimension fitting. The interval velocity model building method disclosed by the invention has the following positive effects: in the interval forming process, data is pretreated by utilizing the concepts of grid and hanging wall and footwall of faults, the concept of group of faults is also introduced, so that an interval time model is built more efficiently; a certain number of primary interval velocity data is utilized to fit the velocities of the hanging wall and the footwall of the faults more accurately, so that a more accurate velocity model is obtained.

Description

technical field

[0001] The invention belongs to the technical field of geological modeling, in particular to a layer velocity model building method under complicated geological conditions. Background technique

[0002] In the process of geological exploration, seismic velocity is an indispensable parameter for structural interpretation such as time-depth conversion, lithology prediction, and structural modeling. Accurately establishing a seismic velocity model is one of the important tasks in the process of geological exploration. In order to establish an earthquake velocity model, it is first necessary to establish a horizon time model, and then fill the horizon velocity into the established horizon time model in an appropriate way. Now briefly describe these two steps and how to achieve them:

[0003] 1) Establish an accurate horizon time model: This step requires gridding the original horizon data and generating horizons. The horizon data gridding is to use the original...
