Embodiment Construction
[0030] The plugging method of seismic source blast hole, it comprises the following steps:
[0031] 1) Preparation of the sealing agent forming cylinder for seismic exploration: the sealing agent forming cylinder for seismic exploration is composed of an inner liner 2 and a porous plastic shell 1; the material of the inner liner 2 is non-woven fabric, and the inner liner 2 is cylindrical. One end of the liner 2 is a sealed end, and the other end of the inner liner 2 is an open end; the plastic shell 1 is cylindrical, the right end of the plastic shell 1 is a sealed end, the left end of the plastic shell 1 is an open end, and the plastic shell 1 is opened. Holes 8 (covered with holes 8), the sum of the areas of the holes 8 accounts for 40% to 80% of the total area of ββthe plastic shell;
[0032] 2) Select the plastic casing 1 according to the diameter of the seismic source blast hole 10, the diameter of the plastic casing 1 is 6-15mm smaller than the diameter of the seismic so...

The invention relates to a sealing method for the vibrating source blast hole in seismic exploration, which is characterized by comprising the steps of: (1) preparing a seismic exploration sealing agent forming barrel; (2) arranging the sealing angle from the open end of an liner into the liner, compressing to a demanded charge density, arranging the liner with the sealing agent into the chamber of a plastic shell to form a section of seismic exploration sealing agent pole; (3) charging a seismic source agent package into the seismic source blast hole, connecting 2 to 6 of seismic exploration sealing agent poles to form a seismic exploration sealing agent pole group to be arranged into the seismic source blast hole to reach the bottom of the seismic source blast hole, wherein when charges the seismic exploration sealing agent pole groups into the seismic source blast hole, the water in the seismic source blast hole should submerge the seismic exploration sealing agent pole groups. The sealing method can resolve the technical problems such as the energy of the seismic source agent package is dispersed early and has large loss, to improve the exploration depth and accuracy of seismic exploration and reduce the effect of blasting on environment in seismic exploration.
Description
technical field [0001] The invention belongs to the technical field of seismic exploration, and in particular relates to a plugging method for seismic source blast holes. Background technique [0002] Seismic prospecting is a method of geophysical prospecting based on the elasticity of rock. Seismic exploration uses artificial methods to excite elastic waves (seismic waves) in rocks, and uses seismic exploration instruments to detect ground vibrations at different positions along the survey line; records and stores the detected data in digital form, and extracts meaningful information through computer processing; Finally, the exploration results are displayed in the form of geological interpretation; thus the purpose of ascertaining the geological structure and census prospecting is achieved. Seismic prospecting has become the most effective method in petroleum prospecting. According to statistics, 90% of the total investment in petroleum prospecting in developed countries ...
