Abstract
The utility model discloses an overspeed poly energy seismic charge column, which is designed as a new main charging structure for increasing the exploration resolution and increasing the formed earth-quake wave energy. According to the principle of overspeed poly energy of the dynamite, the main charging structure is designed into a tubular charging structure, a columnar hollow cavity socket is arranged in the dynamite, the overspeed poly energy blast wave is formed in the column after the blasting, high frequency seismic signal can be generated, and the purpose of increasing the resolution of the seismic data is achieved. According to the need of the energy of the target stratum of exploration, overspeed poly energy seismic charge columns with different external diameters and different doses can be selected.
Description
Technical field
The utility model discloses the explosive source powder column that a kind of geophysical prospecting for oil is used, particularly a kind of Overspeed poly energy seismic charge column that is suitable for the exploration use of oil ground.
Technical background
At present, in geophysical prospecting for oil, conventional explosive source loaded constitution is roughly the same, be solid column structure, Chinese patent 00229323 or 99222458 for example, the energy of generation can not be concentrated, the exploration resolution is low, the demand for development of incompatibility high resolution seismic prospecting.
Summary of the invention
The purpose of this utility model provides a kind of Overspeed poly energy seismic charge column, for improving the exploration resolution, the seismic wave energy of formation is improved, and has designed a kind of novel main charge structure.Adopt explosive hypervelocity cumulative principle, main charge is designed to the hollow charge structure, and a column cavity cave is arranged in explosive, and formation hypervelocity cumulative shock wave is gathered in the back of detonating in the column cave, can produce high-frequency seismic signal, reach the purpose that improves the seismic data resolution.
For achieving the above object, the technical solution adopted in the utility model is: on the basis of general cylindricality explosive-source explosive post, adopt hypervelocity cumulative principle, detonation product is concentrated to the axis of powder column behind explosive charge, accumulate high speed, high pressure draught, form the overvoltage detonation wave, and produce the superenergy seismic event.The utility model mainly is made up of parts such as initiating explosive shell, initiating explosive, draw-in groove, flame proof piece, main charge shell, main charge, cylindrical holes, main charge adopts to be annotated dress or press-fits high explosive, external diameter is that Φ 60-80mm is cylindrical, and the center is cylindrical hole 8 or less than 10 ° conical bore structure.According to the needs of exploration zone of interest energy, can select the Overspeed poly energy seismic charge column of various outer diameter, different doses for use.
The utility model improves loaded constitution on the basis of original cylindricality explosive-source explosive post, produces explosion energy and concentrates, can increase explosion energy, explosion time produces superenergy ripple vertically downward, can improve exploration resolution, substitutes existing common explosive-source explosive post.
Description of drawings
Fig. 1 is the utility model structural representation.
1 is that blind nut, 2 is that initiating explosive shell, 3 is that initiating explosive, 4 is that draw-in groove, 5 is that flame proof piece, 6 is that main charge shell, 7 is that main charge, 8 is that cylindrical hole, 9 is a guiding cap among the figure.
Embodiment
Describe embodiment of the present utility model in detail below in conjunction with accompanying drawing: the utility model main charge 7 is the external diameter of cylindrical Φ 60-80mm, has the explosive load of 1-2kg, center to have cylindrical hole 8 or less than the conical bore structure of 10 ° of cone angles according to diameter.Initiating explosive 3 is provided with cap well, the inert material flame proof piece 5 that main charge 7 surface of contact have two round platforms to constitute, its effect is that the blocking-up propagation of explosion transmits to cylindrical hole 8, and act directly on main charge 7 planes, can change simultaneously the detonation waveform of propagation of explosion in powder column, control detonation direction and detonation reach the time of cylindrical hole 8.Initiating explosive shell 2, main charge shell 6 adopt plastic housing, are provided with to connect with draw-in groove 4 structures.Initiating explosive shell 2 and main charge shell 6 respectively have two outside cylinder boss on same cross section, phase place is 180 °.It is 180 ° inner card cage that two phase places are arranged on the main charge shell 6, and draw-in groove is by slightly becoming the translot of helix angle to form on one section axial vertical slot and the circumference moulded in the shell internal diameter.
The utility model is according to exploration needs dose difference, and with initiating explosive 3 and 7 combinations of more piece main charge, the draw-in groove 4 of during use cylinder boss being packed into is rotated in place along draw-in groove 4.Simple to operate, connect reliable.
The utility model is applicable to oil, geologic prospectings such as coal, select the Overspeed poly energy seismic charge column of various outer diameter, different doses for use according to the tectonic structure situation, it has Applicable temperature, the soaking time of common explosive-source explosive post and the reliability etc. that detonates, transportation, safe and reliable.
