Embodiment 1
[0022] The invention discloses a method for dynamic well depth design using a surface model, which is characterized in that the steps include:
[0023] a. For the construction area, arrange the construction shot line composed of the excitation shot source and the receiving line formed by the receiver corresponding to each shot point. The field construction personnel shall conduct a field survey and survey of the construction work area, or use remote sensing information to obtain According to the contour characteristics of the construction area, the surface model of the field construction shot line for seismic exploration is established on the computer based on the obtained information;
[0024] b. Place excitation points on the established surface model, and obtain the position of each excitation point through interpolation and extrapolation formulas;
[0025] The surface layer structure is composed of multiple layers, and the similarity coefficient refers to the degree of similarity...
Embodiment 2
[0032] As a specific implementation of the present invention, firstly, based on the field survey results, and using a small amount of micro-logging or small refraction as constrained control conditions, a surface structure model is established for the seismic exploration area, and each excitation point is obtained by interpolation and extrapolation s position. After determining the unit location of each excitation point, according to the design requirements of the observation system, it is necessary to design the well depth and explosive charge of the excitation point. Fill in the amount of drug required for each excitation point in the column of drug amount, and then set the well depth calculation parameters (the depth from the high-speed top, the unit length of the drug amount, and the maximum well depth and minimum well depth of the optional limit items), and then determine the The schematic diagram and data of the drilling depth required for each excitation point of this su...
