Wherein, the number of the second cannelure on connecting axle 102 excircle can be arranged according to demand, and the present embodiment does not do concrete restriction to this.By arranging the second cannelure on connecting axle 102, and the 3rd sealing ring 111 is sleeved on the second cannelure can prevents connecting axle 102 and hydraulic pressure wet goods liquid comes into contact, thus prevent connecting axle 102 to be corroded.
As a kind of embodiment, in connecting axle 102 inner chamber, be provided with step.
As a kind of embodiment, body 101 excircle is provided with at least one rectangular through slot, the external screw thread of connecting axle 102 is provided with vertically the elongated slot of at least one.
Wherein, the quantity of rectangular through slot is consistent with the quantity of elongated slot, the corresponding elongated slot of each rectangular through slot, and each rectangular through slot communicates with corresponding elongated slot.
As a kind of embodiment, sealing shroud 103 is interconnected with the endoporus of connecting axle 102.
The operating principle of this sandblaster is: after body 101 is connected with connecting axle 102, and define an airtight annular space, this annular space is as the gas storage space of gases at high pressure.As shown in Figure 1, the lower end of connecting axle 102 is provided with external screw thread, and the lower end of body 101 is provided with internal thread, thus both can connect.And being less than the diameter of body 101 due to the diameter of connecting axle 102, connecting axle 102 can form airtight annular space with body 101.Body 101 top inner chamber is provided with step, and above step, the diameter of inner chamber is less than the diameter of inner chamber below step, and connecting axle 102 has a segment distance between top distance step, now can't form airtight annular space between connecting axle 102 and body 101.When sealing shroud 103 is placed into after in body 101, because sealing shroud 103 upper part is arranged in the inner chamber above body 101 step, and lower part is arranged in the inner chamber of the connecting axle 102 below body 101 step, and by the second sealing ring 109 is sleeved on the first cannelure on sealing shroud 103, thus make connecting axle 102 can form airtight annular space with body 101, and be filled with high pressure nitrogen by the air inlet arranged in the middle part of body 101 to airtight annular space, and by Intake shaft 106, air inlet is closed after inflation completes.
Wherein, as shown in Figure 1, sealing shroud 103 can slide up and down in the vertical direction of present position.Sandblaster is before entering well, and sealing shroud 103 can be fixed by shear pin 110 and body 101, thus sealing shroud 103 can not down be slided.Now, sealing shroud 103 present position can cover in the sand jet outlet on body 101 side.
Sandblaster is connected between two packers by designing requirement, with pressure break oil pipe by sandblaster and packer connected in series, and sandblaster to be placed on the position of design.When after two packer settings, then in oil pipe, drop into bead.Wherein, little club rolls in the inner chamber of body 101.Because sealing shroud 103 is arranged in the inner chamber on body 101 step, therefore, little club is rolled in sealing shroud 103.
As shown in Figure 1, due to sealing shroud 103 upper port, place is funnel-form, and the diameter at sealing shroud 103 upper port place is diminishing gradually.Therefore, after bead is rolled into the lower port place of sealing shroud 103, can due to the diameter being directly less than bead of lower port, and bead be stuck.Meanwhile, because bead has blocked the lower port of sealing shroud 103 just, the space more than lower port of sealing shroud all becomes confined space.
Now above bead, add pressure, as pumped into fracturing fluid by pressure break pump truck to tubing string, the inner chamber namely to body 101 pumps into fracturing fluid, can produce hydraulic pressure.When pressure arrives certain value, as 20 to 22Mpa (MPa), shear pin 110 can rupture because downward tension force is too large.Shear pin 110 rupture after, sealing shroud 103 just can not be continued to be fixed on body 101, and can due to the pressure of top slide downward.
When sealing shroud 103 slides into certain position, sand jet outlet just can expose.When sealing shroud 103 continues glide and slide to the inner chamber of the connecting axle 102 below body 101 step, because on connecting axle 102, the step of top distance body 101 has certain distance, namely connecting axle 102 there is certain space between top and the step of body 101, the airtight annular space that then now connecting axle 102 and body 101 are formed can be broken, and the high pressure nitrogen that interior volume stores upwards can be overflowed by step.Due to body 101 side above step sand jet outlet no longer hide by sealing shroud 103, then spray rapidly from sand jet outlet under the fracturing fluid pressure that can be formed at high pressure nitrogen and enter stratum, neighbouring rock and drilling damage zone produce microcrack under the effect of high pressure nitrogen, thus pressure when effectively can reduce pressing crack construction.
Wherein, be provided with elongated slot if body 101 is provided with on rectangular through slot or connecting axle 102, then fracturing fluid can flow to sand jet outlet with high pressure nitrogen by rectangular through slot or elongated slot, and the present embodiment does not do concrete restriction to this.
The sandblaster that the embodiment of the present invention provides, is connected with body in body interior by connecting axle, and between connecting axle and body, retention has airtight annular space, and is full of gases at high pressure in airtight annular space.Owing to being filled with gases at high pressure in airtight annular space, when needing to spray fracturing fluid from the sand jet outlet of body side, gases at high pressure can provide enough large pressure to improve jet velocity, thus comparatively fast can reduce pressure.Therefore, the efficiency of step-down is higher.
Those skilled in the art, at consideration manual and after putting into practice invention disclosed herein, will easily expect other embodiment of the present invention.The application is intended to contain any modification of the present invention, purposes or adaptations, and these modification, purposes or adaptations are followed general principle of the present invention and comprised the undocumented common practise in the art of the present invention or conventional techniques means.Manual and embodiment are only regarded as exemplary, and true scope of the present invention and spirit are pointed out by claim below.
