Abstract
The utility model discloses a delaying detonating tool of delayed and superposed seismic focus in seismic prospecting. The utility model which overcomes the disadvantage in the prior art combines a plurality of function parts, such as detonating percussion caps, etc., which are arranged in the delaying detonating tool, with the conventional seismic focus explosive column to form the delayed and superposed seismic focus. The utility model has the advantage of safe independent transportation and storage. Casings of the delaying detonating tool, which are connected up and down by threads, can be combined to be lengthened as required. The required length of the detonating percussion cap is calculated according to parameters, such as earth surface speed, the detonation velocity of the conventional seismic focus explosive column, the length of the conventional seismic focus explosive column, etc., thereby, reasonable matching is achieved. One or a plurality of delaying detonating tools are adopted according to geological situations to form two stages or a plurality of stages of delayed and superposed seismic focus, thereby, the effect of explosion energy superposition is generated to enhance signal energy and to improve signal-to-noise ration and resolution.
Description
Technical field
The utility model discloses a kind of geophysical prospecting for oil construction appliance, particularly a kind of delay detonation tool that is suitable in the seismic prospecting usefulness delayed stack source.
Technical background
At present, in oil seismic exploration, general focus is led quick-fried device, and for example Chinese patent 00214990, comprises explosive and Nonel detonator, and explosive is spaced apart with leading quick-fried device, constitutes multistage focus and reaches the delay Overlay.Chinese patent 97245556, the seismic prospecting directional shooting delayed stack source of employing excites the element and the medicine box that detonates to form by the priming device metal, and the explosion fragment device acts on the medicine box that detonates, and ignites the percussion powder column.Above-mentioned focus is led explosive and detonator simultaneously in the quick-fried device, be unfavorable for transporting safely requirement, and seismic prospecting directional shooting delayed stack source excites the next stage focus that detonates by hardware, and complex structure can not arbitrary combination, and inconvenient operation.
Summary of the invention
The purpose of this utility model provides a kind of shell focus of moulding and postpones detonation tool.Postponing to be equipped with in the detonation tool a plurality of function parts such as Nonel detonator, is independently parts, is combined into delayed stack source with conventional explosive-source explosive post, simple in structure, transports separately and stores fool proof.
For achieving the above object, the technical solution adopted in the utility model is: focus postpones to be equipped with in the detonation tool a plurality of function parts such as Nonel detonator, and the housing that postpones detonation tool can connect up and down by screw thread, as required the combination lengthening.Base area indicated airspeed degree, calculation of parameter such as the explosion velocity of conventional explosive-source explosive post and length go out the length of required Nonel, reach reasonable coupling.
Description of drawings
Fig. 1 is the utility model structural representation
1 is that capping, 2 is that Nonel detonator, 6 be protecting cover, 7 be reinforcement, 8 be automatic pack hole for leading quick-fried flexible pipe, 4 for moulding shell, 5 for encouraging the plug that detonates, 3 among the figure.
Embodiment
Describe embodiment of the present utility model in detail below in conjunction with accompanying drawing: the Nonel of Nonel detonator 5 passes the quick-fried flexible pipe 3 of the assistant director of a film or play can play barrier action, guarantees Nonel detonator 5 smooth propagation of explosions.Clip slot that quick-fried end stretches out by capping 1 and excitation plug 2 center pits that detonate of leading of Nonel detonator 5 are fixedly clamped in moulding shell 4.The mode of this fixedly Nonel is not only solid and reliable, and the impact wave energy that encourage the plug 2 that detonates to receive top explosive-source explosive posts generation guarantee to encourage Nonel to detonate.Mould shell 1 increase reinforcement 7 and automatic filler opening 8, reinforcement 7 has strengthened moulds shell 4 rigidity, and filler opening 8 can make and postpone detonation tool automatic filling well liquid when going into the well use automatically, not only helps the Nonel propagation of explosion, also helps preventing the delayed stack source come-up.Protecting cover 6 is provided with internal and external screw thread, and moulds shell 4 and is connected, and protects detonator not to be impacted at ordinary times, guarantees carrying, stores safety.
The utility model is applied to geologic prospectings such as oil, coal.Select for use one or several to postpone detonation tool according to geological condition and form secondary or multilevel delay stack focus, thereby produce the explosion energy Overlay, improve signal to noise ratio (S/N ratio) and resolution with the enhancing signal energy.
