Description

Fracturing sand blower

Technical Field

The utility model relates to the technical field of petroleum industry, in particular to a fracturing sand blaster.

Background

The separate-layer fracturing is a fracturing production-increasing measure process commonly used in oil exploitation operation, and a fracturing fluid consisting of a sand-carrying fluid, a propping agent and the like is sprayed out at high pressure to fracture an oil layer, so that a crack is generated in the oil layer or the crack is opened and expanded, a large amount of liquid is percolated into the oil layer through the wall surface of the crack, the permeability of the oil layer is increased, the oil flow resistance is reduced, and the yield of an oil well is improved.

The existing fracturing sand blaster moves inside a sleeve when in use, and moves to the liquid sprayed out which is poured into from the outside after being in a proper position, but after the spraying is finished, the soil mixed liquid impacted by the liquid enters the sand blaster along the original path, so that the subsequent sand blaster is troublesome to clean when being taken out.

SUMMERY OF THE UTILITY MODEL

The utility model provides a fracturing sand blaster, which solves the technical problem that the impacted soil mixed liquid can enter the sand blaster to cause difficulty in subsequent cleaning.

In order to solve the technical problem, the fracturing sand blaster provided by the utility model comprises a sleeve, wherein a sand blasting pipe is fixed at the lower end of the sleeve, a rubber ring is fixed inside the sand blasting pipe, a blocking ball is arranged at the lower end of the rubber ring, and a blocking pipe is arranged on the surface of the sand blasting pipe;

the blocking pipe comprises a pipe wall, a positioning frame is fixed on the inner surface of the pipe wall, a spring is fixed at the front end of the positioning frame, a blocking plate is fixed at the front end of the spring, and a limiting ring is arranged on the outer surface of the blocking plate.

Preferably, the surface of the sand blasting pipe is provided with an opening, the opening surrounds the sand blasting pipe, and a pipe wall is fixed inside the opening.

Preferably, the locating rack is arranged towards the inside of the sand blasting pipe, and the surface of the blocking plate is provided with a clamping groove.

Preferably, the limiting ring is clamped inside a clamping groove in the surface of the blocking plate, and the distance between the blocking plate and the positioning frame is equal to the normal length of the spring.

Preferably, the diameter of the outer surface of the blocking ball is larger than the diameter of the inner surface of the rubber ring.

Preferably, the surface of the locating rack is provided with a groove, the groove is annularly formed in the surface of the locating rack, and a spring is fixed in the middle of the locating rack.

Compared with the related art, the fracturing sand blaster provided by the utility model has the following beneficial effects:

the utility model provides a blocking pipe, which limits the position of a blocking plate through a spring, so that the blocking plate can enable fracturing fluid to flow out under the action of pressure, and when the water pressure is insufficient, the blocking plate is attached to a limiting ring to block external soil mixed liquid from entering the interior of a sand blaster, thereby avoiding the trouble caused by subsequent cleaning of the mixed liquid in the sand blaster and ensuring the long-term use of the sand blaster.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments; all other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The embodiment is shown in figures 1-3, and the utility model comprises a fracturing sand blaster, which comprises a sleeve 1, wherein a sand blasting pipe 3 is fixed at the lower end of the sleeve 1, a rubber ring 5 is fixed inside the sand blasting pipe 3, a blocking ball 4 is arranged at the lower end of the rubber ring 5, and a blocking pipe 2 is arranged on the surface of the sand blasting pipe 3;

the blocking pipe 2 comprises a pipe wall 25, a positioning frame 24 is fixed on the inner surface of the pipe wall 25, a spring 23 is fixed at the front end of the positioning frame 24, a blocking plate 21 is fixed at the front end of the spring 23, and a limiting ring 22 is arranged on the outer surface of the blocking plate 21.

The working principle is as follows:

moving a sand blasting pipe 3, aligning the sand blasting pipe 3 with a sleeve 1, extruding the sand blasting pipe 3 to extrude the sand blasting pipe 3 on the surface of the sleeve 1, adding the sand blasting pipe 3 at the bottom of the sand blasting pipe 3, placing the sand blasting device into a pipeline at the ground bottom after the sand blasting device is installed, when the sand blasting device moves to a proper position, leading a blocking ball 4 into the pipeline at the ground bottom, blocking the blocking ball 4 by a rubber ring 5, leading fracturing fluid into the pipeline at the ground bottom, blocking the fracturing fluid by the blocking ball 4 and entering the pipe wall 25 through a positioning frame 24, extruding the blocking plate 21 by the fracturing fluid with high pressure to move the blocking plate 21 in the pipe wall 25, moving the blocking plate 21 to drive a spring 23 to deform, leading the fracturing fluid to flow out from a gap between the blocking plate 21 and a limiting ring 22, fracturing the flowing high-pressure fracturing fluid to fracture an oil layer, enabling the oil layer to generate cracks or open cracks and expand, and a large amount of fluid flows into the oil layer through the wall surface of the cracks, the infiltration ability of oil reservoir has been increased, reduces the oil flow resistance, improves the output of oil well, continues leading-in diameter continuous increase's jam ball 4 in proper order to the underground piping is inside, because the increase of 5 diameters of 3 inside rubber rings of follow-up sand blasting pipe, leads to the different jam balls 4 of diameter to stop inside the sand blasting pipe 3 of difference, guarantees to carry out the fracturing to the oil reservoir of different distances.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the utility model, the scope of which is defined in the appended claims and their equivalents.
