Description
Technical field
The present invention relates to drain filter device more particularly to a kind of pressure break filtering sled are returned after a kind of pressure break.
Background technique
In separate stratum fracfturing, need to bore bridge plug after one layer of every pressure break, the clast for boring bridge plug is discharged with mud, if not into
Row processing, fracturing fluid is wasted, and is needed to result in waste of resources with fracturing fluid again, is increased pressure break cost.
To reuse fracturing fluid, the liquid ejected that returns that bridge plug is bored after pressure break need to be handled, usually
The equipment such as desander, desilter are needed, but big particle not can enter desander, for this reason, it may be necessary to need to set in desander front end
A pressure break filtering sled is counted, coarse filtration is carried out to fracturing outlet liquid, is entering desander after coarse filtration.
Summary of the invention
The present invention provide in order to solve problem above a kind of structure be simple and convenient to operate, be convenient for installation and maintenance, filtering effect
The pressure break that fruit is good, saves fracturing fluid, reduces operating cost filters sled.
The technical scheme is that the filtering sled includes that pedestal and the pressure break being mounted on the base filter manifold,
The described pressure break filtering manifold is made of plug valve, four-way pipe, tee tube, straight tube and filter, between them respectively by by
Nonyl connection in " in " shape, the filter is made of outer tube, screen pipe, concentric reducer, quick coupling seat and quick coupling, institute
Several eyelets are disposed on the screen pipe stated, described screen pipe one end is threadedly coupled with quick coupling, and the other end is inserted in size
In head inner hole, the quick coupling is mounted on quick coupling seat.
The pedestal is welded by fashioned iron.
The configuration of the present invention is simple, easy to operate, convenient for installation and maintenance, filter effect is good, save fracturing fluid, reduce operation at
This.
Detailed description of the invention
Fig. 1 is structural schematic diagram of the invention.
Fig. 2 is structural schematic diagram of the invention.
1 is pedestal in figure, and 2 be pressure break filtering manifold, and 2-1 is plug valve, and 2-2 is four-way pipe, and 2-3 is tee tube, and 2-4 is
Straight tube, 2-5 are filters, and 2-6 is union, and 2-7 is outer tube, and 2-8 is screen pipe, and 2-9 is concentric reducer, and 2-10 is quick coupling
Seat, 2-11 is quick coupling, and 2-12 is centre bore.
Specific embodiment
Pressure break filtering sled, the filtering sled includes pedestal 1 and the pressure break being mounted on pedestal 1 filtering manifold 2, described
Pressure break filtering manifold 2 is made of plug valve 2-1, four-way pipe 2-2, tee tube 2-3, straight tube 2-4 and filter 2-5, between them
Respectively by union 2-6 connection in " in " shape, the filter 2-5 by outer tube 2-7, screen pipe 2-8, concentric reducer 2-9, fastly
Quick access headstock 2-10 and quick coupling 2-11 is constituted, and is disposed with several eyelets, the screen pipe 2- on the screen pipe 2-8
8 one end are threadedly coupled with quick coupling 2-11, and the other end is inserted in concentric reducer in the hole 2-9, the quick coupling 2-11 installation
On quick coupling seat 2-10.
The pedestal 1 is welded by fashioned iron.
In use, the centre bore 2-12 of quadrangle is blocked and (is used so under normal circumstances) with plug, intermediate straight tube 2-4
Plug valve 2-1 and left side plug valve 2-1 close, return drain from import enter, plug valve 2-1, filter 2- through right side
5, plug valve 2-1 flows out to next device to outlet；When fluid passes through filter 2-5, big particulate debris or other dirty
Thing is stayed under the blocking of screen pipe 2-8 in screen pipe 2-8, when needing replacing in screen pipe 2-8 full of clast, is first opened
The plug valve 2-1 in left side, the plug valve 2-1 turned off in right side plug valve 2-1, straight tube 2-4 are still closed, and fluid is just from left side
Screen pipe 2-8 is extracted out at this point, opening right side quick coupling 2-11, outwells dirt in screen pipe 2-8 by filtration channel outflow,
It rinses well, is reloaded into outer tube 2-7, for use, when not needing filtering such as, open the plug valve 2-1 of straight tube 2-4, close two sides
Plug valve 2-1, fluid are directly flowed out from intermediate straight tube 2-4.
