Abstract
The caseless pressure generator belongs to a mechanism of the oil industry system, which is mainly used for the technical aspect of high energy gas fracturing and sand controlling. The utility model is composed of a caseless powder cavity, an elastic ignition system and a buffer system, and is characterized in that an igniter (2) is arranged in the ignition cavity (3), the upper part of the ignition cavity is sealed by a sealing plug (1), and the lower part is connected with a central cover (5); the cavity of the powder cavity is composed of two press caps (4) and the central cover (5), and the outside layer of the cavity of the powder cavity (6) is wrapped by a cladding layer (7); the connection pipe (9) in the middle is connected with two central covers (5) and (15) through an upper screw thread and a lower screw thread, and wherein, the central cover (15) is connected with an end block (10); the sub-igniters (8) and (14) are arranged at the end block (10) and the connection pipe (9), and the bottom cover (11) and the buffer block (12) are screwed with the bottom of the caseless pressure generator by the bolt fastening. The utility model has the main advantages of easy and effective use, higher ignition efficiency, good burst effect, lower fabrication cost, and better fracturing and sand-controlling effects.
Description
One, technical field: no shell-type pressure generator belongs to a kind of mechanical device of petroleum industry system, is mainly used in high enegry gas fracturing sand control technique aspect.
Two, technical background: at petroleum industry system, the enforcement of high enegry gas fracturing sand control technique needs special pressure generator to realize, military project pressure generator complex structure is costly, is difficult to use in oil-gas field development.And at present the commonplace application of oil gas field be that the shell-type pressure generator is arranged, expense is higher on the one hand for this generator, the chip that produces of its shell blast easily produces injury to the stratum and pollutes on the other hand.
Three, summary of the invention: according to the defective of above existence, the purpose of this utility model provides no shell-type pressure generator, solves above defective, has made the DISCRETE ELASTIC SUPPORTS ignition system, improves ignition effectiveness; The no shell gunpowder chamber that makes has guaranteed explosive effect, and in addition, the stable buffer system of making and settlement can alleviate the injury of blast to tubing string, improves pressure break, sand controlling result.Top of the present utility model partly is made of sealing-plug, igniter, igniting chamber, gland, central tube, gunpowder chamber and cladding and auxiliary magnet gunpowder, and its underpart is stifled by tube connector, tail, bottom, buffer stopper, execute tight bolt and form with auxiliary magnet gunpowder and center.It specifically connects to form like this: mounting points firearm in the igniting chamber, it on by sealing-plug sealing, its down and screwed connection of center, two glands and center formation gunpowder chamber cavity swathe cladding at the cavity skin; Constitute a flare system by gland, center, gunpowder chamber and cladding.Middle tube connector is by screwed connection two center up and down, and it is center and screwed connection down, and the auxiliary magnet gunpowder is installed in the stifled place of tail, be equipped with at the stifled place of tail simultaneously supporting buffer stopper, bottom, with execute tight bolt formation.The beneficial effects of the utility model are to use convenient and swift, improved ignition effectiveness, guaranteed explosive effect, reduced cost, improved pressure break, sand controlling result.
Four, description of drawings: as figure is structural representation of the present utility model
Among the figure 1, sealing-plug 2, igniter 3, igniting chamber 4, gland 5, center 6, gunpowder chamber 7, cladding 8, auxiliary magnet gunpowder 9, tube connector 10, tail stifled 11, bottom 12, buffer stopper 13, execute tight bolt 14, auxiliary magnet gunpowder, 15, center
Five, embodiment: as seen from the figure, mounting points firearms 2 in the igniting chamber 3, its top is by sealing-plug 1 sealing, and its underpart is connected with center 5, the cavity in two glands 4 and center 5 formation gunpowder chambeies 6, the cavity skin in gunpowder chamber 6 swathes cladding 7; By center 5, gland 4, gunpowder chamber 6 constitute a flare system with cladding 7.Middle tube connector 9 passes through two center of screwed connection 5,15 up and down, and wherein center 15 is connected with tail stifled 10, at tail stifled 10 and tube connector 9 places auxiliary magnet gunpowder 8,14 is installed, and bottom 11, the buffer stopper 12 of its bottom connect and compose by executing tight bolt 13.During use, the utility model is arrived the precalculated position down, light a fire with well head initial igniter 2, gunpowder is from igniting chamber 3, center 5 cavity transmission, and light auxiliary magnet gunpowder 8, temperature moment raising, thus the gunpowder in the gunpowder chamber 6 of igniting produces high energy gases, gas pressure will make formation rock change, and reach the purpose of improving formation parameter.This generator bottom is equipped with buffer stopper 12, can alleviate the downward pressure that blast produces, and guarantees the horizontal action effect of high energy gas.
Claims (2)
1. there is not the shell-type pressure generator, making and settlement have or not shell gunpowder chamber, DISCRETE ELASTIC SUPPORTS ignition system and buffer system, the interior mounting points firearm in chamber (3) (2) is characterized in that lighting a fire, its top is sealed by sealing-plug (1), its underpart is connected with center (5), two glands (4) and center (5) constitute the cavity in gunpowder chamber (6), cavity skin in gunpowder chamber (6) swathes cladding (7), middle tube connector (9) passes through two center of screwed connection (5) up and down, (15), wherein center (15) is connected with tail stifled (10), locate to be equipped with auxiliary magnet gunpowder (8) at tail stifled (10) and tube connector (9), (14), the bottom (11) of its bottom, buffer stopper (12) connects and composes by executing tight bolt (13).
By the described no shell-type pressure generator of claim 1, it is characterized in that 2, gunpowder chamber (6) constitute a flare system with cladding (7) by center (5), gland (4).
