Background technology
Under oil well in the completion process, during the well section construction operation of, complicated geological condition low, often to adopt measures such as overbalanced perforation, pressure break to the stratum production capacity; At present; When the malleation measure is provided, generally adopt the full pit shaft of well head to boost or use composite gun perforation medicine cake at the measure interval, expiring the pit shaft pressurization, to employ equipment many; The cost height that boosts, the difficulty of boosting is big; Compound medicine cake is to carry out synchronously with perforation basically, and it is weak to produce positive pressure.
The utility model content
The purpose of the utility model provides a kind of pressure-generating device, to solve the cost height that boosts that exists in the existing malleation measure, the problem that the difficulty of boosting is big.
The utility model adopts following technical scheme:
A kind of pressure-generating device; Comprise high-energy source powder column, starting mix pipe; It also comprises pressure release housing, center controlled biography fire device, regulating part, gland, relief hole jam, and said center controlled biography fire device is socketed to form by internals and outer part, and it is inboard that said outer part is fixed on the high-energy source powder column; Said internals are provided with the internals flash hole, and said outer part is provided with outer part flash hole; In the said pressure release housing high-energy source powder column is housed; The center that is provided with in the centre bore of said high-energy source powder column controlled biography fire device; Be provided with the starting mix pipe in the controlled biography fire device of said center; Said starting mix pipe upper end is provided with regulating part, and the lateral wall of said pressure release housing is provided with the relief hole jam, and the end of packing into of said pressure release housing is equipped with gland.
The main supporting use of sparking gear during with perforation, fracturing work of the pressure-generating device of the utility model has the nature of igniting, the controlled advantage of boosting, the hyperbaric environment in the time of can effectively operation being provided, powerful guarantee underground work is high-efficiency continuous carries out.The utility model adopts has the protection of shell cavity, can control burning velocity; Adopt disposable direct-fire burning, the closed chamber internal pressure is stable, pressure percussion reliable and stable; The housing of having gone into the well protection, favorable sealing property.
Description of drawings
Fig. 1 is the structural representation of pressure-generating device.
Fig. 2 is the cross-sectional view of the controlled biography fire device of the center in the pressure-generating device.
The specific embodiment
As shown in Figure 1; A kind of pressure-generating device comprises high-energy source powder column 2, starting mix pipe 4, and it also comprises pressure release housing 1, center controlled biography fire device 3, regulating part 5, gland 6, relief hole jam 7; Center controlled biography fire device 3 is socketed to form by internals 32 and outer part 31; Outer part 31 is fixed on high-energy source powder column 2 inboards, and internals 32 are provided with internals flash hole 321, and outer part 31 is provided with outer part flash hole 311; High-energy source powder column 2 is housed in the pressure release housing 1; The center that is provided with in the centre bore of high-energy source powder column 2 controlled biography fire device 3; Be provided with starting mix pipe 4 in the controlled biography fire device 3 of center; Starting mix pipe 4 upper ends are provided with regulating part 5, and the lateral wall of pressure release housing 1 is provided with relief hole jam 7, and the end of packing into of pressure release housing 1 is equipped with gland 6.
Gland 6 can be annular clamp nut.Relief hole jam 7 preferably is at least 4.
Cooperation place, the outer part 31 upper end end face of high-energy source powder column 2 endoporus upper end and center controlled biography fire device 3 is bonding with epoxy resin 8.
The operating principle of the utility model is: after pressure-generating device one termination is received the burning signal of input; Center controlled biography fire device 3 is uniformly distributed with dispersion to the burning signal transients from the inner chamber high-energy source powder column 2 that ignites, and the instantaneous Millisecond anaerobism of high-energy source powder column after the burning, produces the great amount of high-temperature gases at high pressure fully rapidly; Form a positive pressure environment at the underground work interval; For work measure provides necessary condition, improve measure usefulness effectively, accomplish the effect of pressure-generating device.
Fig. 2 shows the cross-sectional view of center controlled biography fire device, and internals flash hole 321 communicates with outer part flash hole 311, and when internals 32 rotated to 0 ° of angle, passing fiery area was 100%, and continue 35 milliseconds burning time; When internals 32 rotated to 5 ° of angles, passing fiery area was 75%, and continue 44 milliseconds burning time; When internals 32 rotated to 10 ° of angles, passing fiery area was 50%, and continue 50 milliseconds burning time, and the malleation duration is just different like this.
The course of work of the utility model is following: with special tool rotation internals 32; The adjustment corresponding angle, change internals flash hole 321 and outer part flash hole 311 to direct proportion, realize controlling ignition area; Reach the result of control burning velocity, the signal that will burn evenly distributes.
Pressure-generating device China and foreign countries part is motionless, and the effect of internals 31 anglecs of rotation is as shown in table 1.
