Method and device for optimizing seismic source production combination mode

Abstract

The invention provides a method and device for optimizing a seismic source production combination mode, and the method comprises the steps: dividing a construction collection region into a plurality of sub-blocks according to the minimum synchronous excitation distance, the distance between two adjacent seismic sources in the vertical direction, and the distance between two adjacent shot points; selecting one Fleet from each sub-block to perform Fleet grouping combination of different sub-blocks, wherein the distance between adjacent Fleets of the same seismic source group is not less than theminimum synchronous excitation distance; acquiring excitation sequencing schemes among different grouped seismic source groups through a permutation and combination method, and calculating acquisition time under different excitation sequencing schemes in a target time period; and selecting an excitation sequencing scheme with the least acquisition time as an optimal seismic source excitation sequence. By utilizing the embodiment of the invention, the minimum synchronous excitation Fleet quantity can be maximized within the same time and space range, and the sustainability of the acquisition operation state can be maintained, so that the optimization of an efficient acquisition mode is realized, and the purpose of improving the production efficiency is achieved.

Description

technical field [0001] The invention relates to the technical field of high-efficiency acquisition and production of vibrators, in particular to a method and device for optimizing the combination mode of vibroseis production. Background technique [0002] With the popularization of high-density spatial sampling technology, high-efficiency acquisition technology of vibrators has been more and more widely used by domestic and foreign oil companies. figure 1 It is a schematic diagram of the distribution of typical "one shot instead of road" shot detection points. In the high-efficiency acquisition project of vibroseis, the method of "using shot instead of road" is usually used for construction. This scheme allows the vibrator to satisfy the time-distance rule (T-D rule). , can carry out construction work more efficiently. The seismic acquisition construction technology requires more and more seismic sources, so it not only brings more and more challenges to the management of o...

Problems solved by technology

Although the fleet distribution was originally designed to balance the construction acquisition efficiency of each fleet, such a source grouping method cannot effectively ensure a more reasonable match between the fleet and the acquisition efficiency in actual production, and thus cannot fully utilize each fleet. Fleet's acquisition efficiency, which affects construction efficiency
