Embodiment Construction

[0061] In order to enable those skilled in the art to better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described The embodiments are only some of the embodiments of the present application, but not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without creative efforts shall fall within the scope of protection of this application.

[0062] Considering that the existing seismic data quality control methods are mostly designed for single-shot records based on conventional seismic data acquisition methods. The aliasing seismic acquisition technology is a different acquisition method from the conventional seismic data acquisition method. Its acquisition range is wider, i...

Abstract

An embodiment of the application provides a quality control method and device of continuously recorded data. The method includes the following steps: continuously recorded data and hypocenter data areacquired, wherein the continuously recorded data is seismic data acquired by aliasing earthquakes; whether broken arrangement exists in the continuously recorded data is detected; if so, a broken arrangement-affected shot point firing time range and a broken arrangement-affected shot point firing stake number range are determined according to the hypocenter data and the continuously recorded data; and a shot is supplemented or stopped according to the broken arrangement-affected shot point firing time range and the broken arrangement-affected shot point firing stake number range. The solutiontakes specific characteristics of the continuously recorded data into consideration, the broken arrangement in the continuously recorded data is determined first, and then the broken arrangement-affected shot point firing time range and the broken arrangement-affected shot point firing stake number range are determined according to the broken arrangement so as to perform targeted real-time quality control processing according to the data, thus solving the technical problem of effective real-time quality control for continuously recorded data.

Description

technical field [0001] The present application relates to the technical field of seismic exploration, in particular to a quality control method and device for continuously recording data. Background technique [0002] With the development of seismic data acquisition technology and the improvement of exploration requirements, vibroseis aliasing seismic acquisition technology has gradually attracted people's attention due to its wide acquisition range and high efficiency. [0003] When the above-mentioned vibrator aliasing seismic acquisition technology is implemented, it is different from the conventional seismic data acquisition method. A separate vibroseis management system will be used to control the source vibration, and the seismic acquisition instrument is required to continuously record the collected data. recorded seismic data. This makes the seismic data obtained based on the aliasing seismic acquisition technology continuous record data, which is different from the...
