Well blowout out-of-control path type ignition system

Technical Field

The present invention relates to the field of oil and gas drilling and extraction technology, a special kind of used for the rescue process blowout blowout source ignite the processing of the transport distance of the blowout outta track type ignition system.

Background Art

Natural gas is the general term for a plurality of combustible gas, the main component include methane, ethane, hydrogen sulfide, carbon dioxide, and so on. Rapid onset generally hydrogen sulfide poisoning, with brain and (or) respiratory system damage-based clinical manifestations, can also be accompanied by heart and other organ dysfunction. The clinical manifestations of the contact factors such as the concentration of hydrogen sulfide are different and have obvious difference, in the most common damage of the central nervous system. After the high-concentration hydrogen sulfide contacting poles electric shock type death may occur, that is, in a few seconds after contacting the respiratory suddenly stopping or within a few minutes, a few minutes later can occur asystole; can also immediately or within a few minutes the coma, and respiratory gathers stops and death. Under natural gas deep buried in the earth's surface, has a certain pressure. In the drilling process of the exploitation of the, underground high pressure, but the bore surrounding the measures taken is not in place, the blowout phenomenon will take place from the underground injection out a large amount of natural gas. Conventional emergency disposal method, to the rapid withdrawal of contaminated personnel wind place leakage, and immediately proceed to the isolation, isolating the minor leakage of 150m, when leakage of the isolation 300m, strictly restricted. The conditions on site frequently well control can not be implemented when the decision operation performed, the released natural gas should be burned, the proportions of the natural gas with the air reach the explosion limit. The traditional technology without special if against blowout natural gas for the ignition processing apparatus, and mainly rely on methods such as manual throw-out source of fire ignition, the existence of these measures such as pole may cause unnecessary casualties; source of the construction personnel too far distance, it is difficult to implement in a timely and effective ignition, poor ignition effect of defects.

Content of the invention

This invention aims at solving the WBC in the traditional high-risk, aging is poor, the technical problem of great operation difficult, can be carried out so as to provide a long-distance well blowout ignition operation, with safety, high-efficient, accurate, and the like-outs of the control track type ignition system.

The purpose of this invention is realized through the following technical scheme.

Blowout of the present invention control track type ignition system, which by the throwing device and ignition body , wherein the front end of the device comprises a propellant missile-projector 1, is arranged at the middle part of the trigger mechanism 2 and the yokes at the tail end of the 4 form; missile-projector 1 through the connecting piece 11 and the trigger mechanism 2 which is connected with, the percussion mechanism 2 by the firing pin 10, on the firing pin 10 the rear hammer 14 and connected with the firing spring to 8, the head and the hammer 14 with the pull of the activities of the 7 form; hammer 14 is provided with a safety pin below 3 ; by ignition body the front section of the incendiary assembly 15, the assembly of the extension of the middle section 16 and the transmission-charge mechanism is arranged on the tail section 17 form.

Blowout of the present invention control track type ignition system, wherein the missile-projector 1 is made of light metal pipe 13 and nested for lightweight metal tube 13 near the periphery of the percussion mechanism 2 of trough of the non-metal casing 12 form.

Blowout of the present invention control track type ignition system, wherein the missile-projector 1 to the inner diameter of Φ 42 mm-Φ 42.2 mm.

Blowout of the present invention control track type ignition system, wherein the states the shoulder request 4 is made of light metal foil 6 at the tail end of the non-metallic bushing and 5 form.

Blowout of the present invention control track type ignition system, wherein the projection device by missile-projector 1 to the front end of the shoulder support 4 at the tail end of the total length is 685 mm -715 mm, the total weight of the 1350 g -1650 grams.

The invention well blowout outta track type ignition system has the beneficial effects:

1. Blowout pressure is large, the use of traditional ignition mode cannot close to the also can not safely ignited sprayed blowout source of poisonous and harmful gas;

2. The ignition effect is high, after the actual measurement of the effective outer bearing ring ≥ 96% of this invention;

3. Ignition distance, distance can be effectively ignited 150 meters away from the combustible gas ejected from the mouth-outs;

4. Suitable for far away from the toxic and harmful gas blowout mouth operation of the casting projecting device, to protect the safety of operators;

5. The operation is simple, only has the advantages of operation training can be familiar to the operation;

6. As the hand throwing mechanism, has a small quality and the recoil impulse.

Yoshikami can be seen, the invention of the blowout outta track type ignition system is applicable to the blowout pressure is large, the use of traditional ignition mode cannot close to the also can not safely ignited sprayed blowout source of poisonous and harmful gas, and with ignition effect is high, the ignition distance, to protect the safety of the operator, the operation is simple, a great deal of technical advantages.
