Specific embodiment
As shown in Figure 1, blind hole combustion gas synergistic perforator in a kind of convergence type of the utility model, be by perforating gun 1,
Perforating bullet firing mount 2 and perforating bullet bullet support 3 are constituted, and the inside of the perforating gun 1 is equipped with perforating bullet firing mount 2, the perforation
The top bolt for playing firing mount 2 secures positioning disk 11, its bottom end secures lower positioning disk 12, upper positioning disk 11 and lower positioning disk
12 are fixed on the inner wall of perforating gun 1.Perforating bullet firing mount 2 is equipped with multiple perforative firing mount holes 13, the inside of perforating bullet firing mount 2
Equipped with multi-openings bullet bullet support 3, is set in perforating bullet bullet support 3 there are three perforative bullet prop hole 4(such as Fig. 2), play prop hole 4 and firing mount hole
13 position is corresponding, in the perforating bullet bullet support 3, is located in the middle the open end of perforating bullet 5 equipped with charge shell 9, dress
Medicine shell 9 is connected on perforating bullet firing mount 2, and energization explosive 10 is housed on charge shell 9, and installing energization explosive 10 additional can significantly mention
High perforation wears depth and perforation tunnel water conservancy diversion area, hence it is evident that improves perforating effect.As shown in Figure 1, the quantity of perforating bullet bullet support 3 is four
It is a, need to be put into more perforating bullet bullet supports 3, the axis of adjacent two perforating bullet bullet supports, 3 bullet mouth plane according to practical well depth
It is 144 ° (as shown in Figure 4) that phase angle is formed between line.The length of perforating bullet bullet support 3 is 20cm, the specific length of perforating gun 1
It is 1 meter, 1.5 meters, 2 meters, 2.5 meters, 3 meters, 3.5 meters, 4 meters, cable perforation provides maximum length perforating gun no more than 4 meters.It penetrates
Hole bullet bullet support 3 is generally uniformly distributed using 5 phases, and phase angle is 360 °/5=72 °, in order to reduce damage of the preforation tunnel to casing
Degree, it is desirable that the remoter perforating bullet group distance the better, if first phase is 0 °, second phase is 144 ° best.It is described
The adjacent perforating bullet bullet support 3 of any two between be equipped with energization powder column 8, the effect of energization powder column 8 is to light a fire to emit in perforation
While, will be arranged in interlayer energization powder column 8 ignite burning, become high temperature and high pressure gas, to established perforation tunnel into
Row pressure break makes perforation tunnel generate crack, improves the water conservancy diversion area of oil gas, lowers the compacted fill ground that perforating bullet generates, thus mentions
High Oil & Gas Productivity.Oil reservoir in oil well is not continuously that the interlayer between oil reservoir and oil reservoir is called interlayer, and interlayer does not need to penetrate
Hole, therefore energization powder column 8 is installed at interlayer.Playing 4 inner seat of prop hole has perforating bullet 5, and the perforating bullet 5 is in open at one end
Hollow body, outer wall shape and bullet prop hole 4 and firing mount hole 13 are adapted；The inside of perforating bullet 5 is equipped with explosive 6, and the surface of explosive 6 is attached
There is cavity liner 14, blind hole 7 is equipped on the inner wall of perforating gun 1, the open end of perforating bullet 5 is opposite with the position of blind hole 7, blind hole
7 be non-penetrative hole, and blind hole 7 can be set in 1 inner wall of perforating gun or outer wall when practical application, and being set to outer wall can be
Burr height is reduced after perforation, be set to inner wall can reduce preforation tunnel intensity, improve the perforating bullet height of burst (perforating bullet front end face arrives
The distance of perforating gun inner wall is the height of burst), perforating bullet can be improved and wear depth.The central axes of adjacent two perforating bullets, 5 bullet mouth plane
Between form angle α (as shown in Figure 3) and 0 °≤α≤20 °, wherein preferably 2 °≤α≤8 °.This angle formula cloth bullet form
It is required that the jet stream of the other two launch holes bullets of the jet ratio of the second launch hole bullet will be grown, three ducts are formed on stratum after perforation, the
One forms angle with Article 3, which is to penetrate stratum different depth according to different perforating bullets to calculate and get.It is required that
It is first duct and Article 3 duct close to Article 2 duct, but cannot intersects with Article 2 duct, avoids perforation resilience energy
Amount loss, guarantees perforating effect.It converges perforation three and sends out bullet interaction, the jet streams of upper and lower two hairs bullet increasingly connect in stratum
The jet stream of nearly second hair bullet, therefore the stress on stratum will be released under the collective effect at the place of convergence in three jet streams, then rely on
The effect of energization powder column can form biggish fan-shaped cavity, therefore the water conservancy diversion area in duct is greatly improved, thus improve
Oil & Gas Productivity.In general, perforating bullet cloth bullet spacing is 62.5mm, this distance be it is fixed, perforating bullet is maximum at present
Jet length is 1800mm, passes through calculating: α=62.5/1800 sin, so the smallest α=2 °.
Blind hole combustion gas synergistic perforator, application method are as follows in a kind of above-mentioned convergence type:
First according to the concrete condition of oil well, the perforating bullet bullet support 3 of needs and the quantity of energization powder column 8 are calculated, then
Perforating bullet bullet support 3 and energization powder column 8 are inserted into perforating bullet firing mount 2 according to predetermined order, and make to play prop hole 4 and firing mount hole 13
Position is corresponding, fixes upper positioning disk 11 and lower positioning disk 12 at the both ends of perforating bullet firing mount 2, then perforating bullet 5 is mounted on
In the bullet prop hole 4 that has aligned and firing mount hole 13, before charge shell 9 is mounted on intermediate perforating bullet 5, the perforation that then will install
It plays firing mount 2 and is pushed into perforating gun 1, finally upper positioning disk 11 is mutually fixed with lower positioning disk 12 in perforating gun 1, makes perforating bullet 5
It is opposite with the position of blind hole 7, that is, complete assembly.
