Auxiliary detonator 6 and auxiliary magnet gunpowder 7 is also provided with between the directed large perforation breaker III of described cumulative and the directed percussion mechanism II of exploding gas.
Operating principle of the present invention is:
According to bit freezing object composition structure and morphological analysis, when bit freezing solid blockade situation is not serious, cumulative directed large perforation breaker III is only needed to implement large perforation to bit freezing junk broken, if bit freezing solid blockade situation is serious, then need the use that the directed percussion mechanism II of exploding gas and cumulative directed large perforation breaker III combines, by oil pipe or cable, this contrive equipment is transferred to bit freezing junk top, be close to tip position, by to clash into or cable energising is detonated igniting initiator I, initiator I is direct initiation cumulative directed large perforation breaker III first, it is broken that cumulative directed large perforation breaker III implements large perforation to bit freezing junk, the metal fever particle that almost moment cumulative directed large perforation breaker III blast produces ignites the directed percussion mechanism II of exploding gas, the high temperature and high pressure gas orientation that the directed percussion mechanism II of exploding gas is produced by detonation powder burning is impacted, wash away broken lax bit freezing object, the effect of vibration that clashes of the bit freezing object that this device adjoint and fragmentation simultaneously relaxes.By and gases at high pressure directed impact broken to the directed large perforation of bit freezing thing, wash away and clash into the powerful comprehensive function vibrated, destruction, loose card thing overall structure, removing bit freezing solid blockade.
The concrete mechanism of the present invention is:
When bit freezing solid blockade situation is not serious, cumulative directed large perforation breaker III is only needed to implement large perforation to bit freezing junk broken, initiator I first direct initiation detonating fuse 8 ignites the responsive medicine 9 of the fire in a stove before fuel is added, flexible linear-shaped charge agent 10 ignited by the responsive medicine 9 of the fire in a stove before fuel is added, flexible linear-shaped charge agent 10 blast makes energy gathering cap 12 form high-speed and high-temperature metal pestle body, directly penetrates broken bit freezing object; If bit freezing solid blockade situation is serious, by clash into or cable energising detonate igniting initiator 1, quick-fried ignition and detonation device 1 is ignited propagation of explosion body 4 inside, center and is placed detonating fuse 8, detonating fuse 8 ignites the responsive medicine 9 of the fire in a stove before fuel is added, flexible linear-shaped charge agent 10 ignited by the responsive medicine 9 of the fire in a stove before fuel is added, flexible linear-shaped charge agent 10 blast makes energy gathering cap 12 form high-speed and high-temperature metal pestle body, directly penetrates broken bit freezing object, completes the design function of cumulative directed large perforation breaker III.
Almost moment flexible linear-shaped charge agent 10 is exploded, beehive-shaped charge housing 11 is broken, the high temperature that blast produces and the effect of metal fever particle are ignited auxiliary detonator 6, auxiliary detonator 6 quick igniting auxiliary magnet gunpowder 7, auxiliary magnet gunpowder 7 ignites from bottom detonation gunpowder 3, detonation gunpowder 3 burning produces a large amount of high temperature and high pressure gas and directly sprays fast from powder charge cylindrical shell 2 bottom, the bit freezing junk destroyed is implemented high speed impact, washed away, the effect of vibration that clashes of the bit freezing object that this device adjoint and fragmentation simultaneously relaxes.Complete the design function of the directed percussion mechanism II of exploding gas.
The present invention is applicable to outwell the complicated special circumstances of bit freezing for what occur in drilling process as tricone bit, and conventional releasing tool is difficult to carry out, or the problem such as implementation cost is high.The object of the present invention is to provide the quick release device that a kind of oil well bit freezing object orientation detonation impact failure is separated, first middle part or eccentricity orientation large perforation destruction is carried out for card thing at bit freezing thing top, broken lax bit freezing object overall structure by this device; Then the high temperature and high pressure gas orientation produced by detonation powder burning is impacted, is washed away broken lax bit freezing object, the effect of vibration that clashes of the bit freezing object simultaneously relaxed with this device and fragmentation.By and gases at high pressure directed impact broken to the directed large perforation of bit freezing thing, wash away and clash into the powerful comprehensive function vibrated, destruction, loose card thing overall structure, removing bit freezing solid blockade.And immediately by transferring this device, card authentication drill chuck thing removing situation, also can trip out this device after being finished, transferring drifting Tool validation card thing and removing situation.Then pull bit freezing object out by Special fishing tool and remain fragment, fast quick-recovery drilling well or oil well are normally produced.This apparatus structure is simple, and construction technology is convenient, and compared with the upper heavy repair task time, the activity duration shortens greatly, and construction cost reduces greatly, can test checking immediately in scene.
Embodiment one
The present invention is carried out the once success of test technique for applying at Zhongyuan Oil Field a bite deep level well bit freezing, obtains positive effect.This well Drilling Design is cemented the well by Multi-stage sleeve and is formed, and straight well section adopts 7 〞, 5
1/
2〞 cased hole completion (setting of casing), creep into horizontal segment, in drilling process, be stuck in straight well pit shaft owing to because of carelessness tricone bit being outwelled during more bit change, bit freezing drill bit can not to lead to, grinds and can't be washed off, on front and back, the overhaul about one wheat harvesting period time of cost, cannot be dealt with problems by various method.For bit freezing object structures and state analysis, finally we pass through the directed large perforation breaker of test of many times research and design cumulative, and adopt cable transmission technique to carry out unfreezing test application, technique is once successful.Salvage prove that splitting into several piece after tricone bit is successfully destroyed falls to shaft bottom by making lead stamp and instrument, sleeve pipe is not caused and damages impact, the drilling well work of fast quick-recovery, demonstrate feasibility and the practicality of apparatus of the present invention technique, successfully solve a bit freezing difficult problem for Special complex bit freezing junk, also can be used for the fast processing of other bit freezings and oil well fish card well accident, for this type of bit freezing junk unfreezing challenge provides new technological approaches and research method.
