Description
Technical field
The present invention is the downhole tool on oil field compression fracture stratum, is a kind of sanding machine available for multiple fracturing.
Background technology
Stratum that will be low to permeability during oil field development carries out pressure break, increases the connectivity on stratum, improves yield.Current
Instrument one layer of general pressure break, multiple layers of position of pressure break such as are wanted, it is necessary to take some special method and steps, this separate stratum fracfturing
Process is more, and construction is complicated, engineering time length, and can not be turned off after sliding sleeve opening, it is impossible to carries out successively pressure break.
The content of the invention
It is an object of the invention to provide a kind of sanding machine available for multiple fracturing, can make fracturing string and need pressure break
Stratum UNICOM and closing, realize multilayer staged fracturing, reduce working procedure, simplify construction, reduce the engineering time.
The object of the present invention is achieved like this：Including top connection, upper shear pin, housing, upper sliding sleeve, upper sealing ring, downslide
Set, nozzle, lower shear pin, lower seal, lower contact, upper sliding sleeve by upper shear pin are fixed on one after being placed in the bottom of top connection
Rise, the upper threaded connection of the lower screw thread and housing of top connection, nozzle is put into lower housing portion, there is linked hole on housing, on nozzle
There is a spray orifice, the spray orifice UNICOM on linked hole and nozzle on housing, low sleeve is fixed on after being placed in lower contact by lower shear pin
Together, the lower threaded connection of the upper screw thread and housing of lower contact, makes low sleeve stretch into housing and nozzle, low sleeve covering nozzles
On spray orifice, the bottom milling of low sleeve is split into bar body, and the bar body can not be expanded outwardly by the inwall constraint of housing, low sleeve
Sealing ring is installed between top and housing, lower seal is installed between low sleeve and lower contact, lower seal is in lower shear pin
Under, and the bottom milling in low sleeve is split on the root of bar body, the internal diameter of upper sliding sleeve is more than the lower inner diameter of low sleeve,
There is reaming in the bottom of lower contact.
The beneficial effects of the invention are as follows：Spray orifice closing and the UNICOM on nozzle can be made, can make upper sliding sleeve after putting into valve ball
Channel jam, the present invention of tripping in different size on fracturing string, it is possible to achieve successively closing and UNICOM, realize multilayer point
Section pressure break, reduces working procedure, simplifies construction, it is possible to reduce the engineering time.
Brief description of the drawings
Accompanying drawing 1 is the Standard figure of the present invention.
Embodiment
1 pair of embodiments of the invention illustrates below in conjunction with the accompanying drawings.
As shown in figure 1, embodiments of the invention include top connection 1, upper shear pin 2, housing 3, upper sliding sleeve 4, upper sealing ring 5,
Low sleeve 6, nozzle 9, lower shear pin 10, lower seal 11, lower contact 12, upper sliding sleeve 4 be placed in the bottom of top connection 1 after by upper
Shear pin 2 is fixed together, and the lower screw thread of top connection 1 and the upper threaded connection of housing 3, nozzle 9 are put into the bottom of housing 3, housing 3
On have linked hole 7, have spray orifice 8 on nozzle 9, the linked hole 7 on housing 3 is placed on the UNICOM of spray orifice 8 on nozzle 9, low sleeve 6
It is fixed together after in lower contact 12 by lower shear pin 10, the upper screw thread of lower contact 12 and the lower threaded connection of housing 3, makes low sleeve
6 stretch into housing 3 and nozzle 9, and the spray orifice 8 in the covering nozzles 9 of low sleeve 6, the bottom milling of low sleeve 6 is split into bar body, the bar
Body can not be expanded outwardly by the inwall constraint of housing 3, and sealing ring 5, low sleeve 6 are installed between the top of low sleeve 6 and housing 3
Lower seal 11 is installed between lower contact 12, lower seal 11 is under lower shear pin 10, and the bottom milling in low sleeve 6
It is split on the root of bar body, the internal diameter of upper sliding sleeve 4 is more than the lower inner diameter of low sleeve 6, has reaming in the bottom of lower contact 12
13。
The effect of upper sealing ring 5 and lower seal 11 is to prevent the perverse leakage of fracturing fluid in low sleeve 6.
Each layer is directed on tubing string needs a set of present invention of position tripping in of pressure break, but the inside dimension of every suit is not
Together, mainly upper sliding sleeve 4, the size of low sleeve 6 are different, become larger from the bottom up.First pressure break basecoat, basecoat pressure
After having split, then valve ball is put into, the valve ball is fallen within the bottom shoulder of the low sleeve 6 in the present invention of layer second from the bottom, suppress
Lower shear pin 10 is cut, low sleeve 6 is descending to expose spray orifice 8, after the bar body that 6 times enforcement its underpart millings of low sleeve are opened reaches reaming 13,
The bar body that milling is opened loses constraint and expanded（Shoulder is coned face in the bottom of low sleeve 6）, fall under the valve ball of input next
On the upper sliding sleeve of level, upper sliding sleeve is set to be blocked, now, the spout in the present invention of layer second from the bottom is to open, other all
Spout do not communicated with stratum, now this layer of position of pressure break.The lamination puts into a valve ball again after splitting end, and this valve ball can pass through
The sliding sleeve of the other layers of position in top, falls in the inner circular bead of upper sliding sleeve 4, then suppresses shear pin 2 and cut, and upper sliding sleeve 4 is descending to be covered
Lid spout 8, the outlet of the set are closed again, can be put into the valve ball on upper strata again, upper strata is started pressure break by UNICOM, so repeatedly
Carry out, realize multi-level pressure break.
