Description

Paying-off detour pile number determining method and system and readable storage medium

Technical Field

The invention relates to the technical field of seismic exploration, in particular to a paying-off detour pile number determining method and system and a readable storage medium.

Background

Natural gas and light oil are used as clean energy sources in fossil energy sources along with the carbon neutralization and the carbon peak target, and the total consumption amount is increased. In order to find more natural gas and light oil resources, the external dependence is reduced, the energy safety is ensured, and the exploration strength of the natural gas and the light oil is gradually increased in China. Hero's land is the dominant force producing zone of the faggots basin, and a number of gas-containing, light oil-containing formations have been found. When the four characteristics of mountain land, dry and loose land, surface anisotropy and complex structure are independently existed, the four characteristics are very large seismic exploration problems, and superposition of four seismic adverse factors in hero areas leads to extremely great challenges for the seismic technology and engineering implementation of the areas, so that the hero areas are once called as "forbidden areas for seismic exploration". Five rounds of earthquake attack have been organized in the hero area since the nineties of the last century, limited to the geophysical prospecting equipment capability at that time, and the attack has very little effect, "five on five off five". By implementing the English east three-dimensional seismic exploration in 2011, the world-class difficult problem of exploration forbidden areas is solved at one time by using the six-upper hero ridge. Since 2011, the hero-cycle exploration pulls open the preamble, but because the regional gully is vertically and horizontally, the resource allocation and in-place difficulty are extremely high, the exploration cost is high, and the core problem is that the large line length of a wired instrument is fixed by 55m and is influenced by the fluctuation of topography, the slope length between two detection points is not fixed, so that the regional resource allocation cannot be reasonably carried out, only the high resource allocation can be adopted, and the mode of less personnel allocation workload is adopted, so that the stable operation of the project is ensured.

Therefore, how to propose a scheme capable of reasonably configuring resources in complex mountain construction according to the slope length between two detection points becomes a problem to be solved at present.
