Embodiment Construction

[0095] Below in conjunction with accompanying drawing, the present invention is described in further detail:

[0096] The present invention has two purposes, one is to propose a new idea and method for automatic first-arrival picking; the other is to improve the effect of automatic first-arrival picking and greatly reduce the workload of manual interactive modification by the processor.

[0097] For the first purpose, a new idea and method of first arrival automatic picking is proposed. Through a lot of research in the early stage, when the seismic data changes rapidly, including large changes in the signal-to-noise ratio and the trend of adjacent traces, etc., A single first-arrival automatic picking algorithm cannot solve the problem of inaccurate first-arrival picking. Therefore, in the present invention, first-arrival picking is no longer regarded as a picking task on a single track, but a picking task in a work area. A series of technical steps are needed to solve the fir...

Abstract

The invention provides an automatic first-arrival picking method and system, belonging to the field of petroleum geophysical exploration in the field of earth science. The method includes: a preprocessing step: inputting the shot set data model, grouping the shot set data models, and obtaining the range of first arrival picking; a comprehensive algorithm calculation step: performing first arrival picking within the range of first arrival picking obtained in the preprocessing step , to obtain the first-arrival result; quality control step: perform quality control on the first-arrival result obtained in the comprehensive algorithm calculation step, and generate quality monitoring files and first-arrival files. The automatic first-arrival picking method of the present invention is fast, accurate and stable, and improves the automatic first-arrival picking effect, greatly reducing the workload of manual interactive modification of a processor.

Description

technical field [0001] The invention belongs to the field of petroleum geophysical exploration in the field of earth sciences, and in particular relates to an automatic first-arrival picking method and system. Background technique [0002] Seismic wave first arrival picking is a very important link in seismic data processing. The efficiency and effect of first arrival picking directly affect the efficiency and effect of static correction, which seriously restricts the processing cycle of the project and the deployment of resources such as manpower and material resources. At the same time, with the continuous expansion of the exploration scope, the data volume of seismic data has increased exponentially, and the seismic data has become more and more complex, which puts forward higher requirements for the first arrival picking method and software. [0003] Existing commercial software and first-arrival automatic picking algorithms have more or less adaptability problems. For d...
