Difference, and it is costly；Coating sand class, ceramic-like sand screen sand block ability are strong, but its poor toughness, collide frangible, difficulty of going into the well
Greatly, expense is also higher.
In prior art, have a kind of material, be called hole geo-polymer, through hole geo-polymer be with metakaolin (or
Burnedc lay) for raw material, industrial waterglass be alkali-activator, at a lower temperature (between 120-200 DEG C), using directly foaming work
Skill prepare, with geo-polymer as skeleton, porous material of good performance.The inside has filled elastic fiber again, improves geology
The pliability of polymer sand block layer, reduces the broken probability that sand screen is gone into the well.The comprcssive strength of the geo-polymer sand block layer can
Up to 9.0Mpa, apparent porosity up to 70%, bulk density between 0.40g/cm3～1.0g/cm3, be resistant to more than 800 DEG C of height
Temperature.Fully meet the technical requirements of oil-water well sand control, and due to its prepare material cheap, preparation process is simple, application cost
Will be far below other sand screens.The geo-polymer sand screen that the application is developed is mainly with through hole geo-polymer as sand block layer
Underground sand-prevention equipment.
Utility model content
The purpose of this utility model is to provide a kind of through hole geo-polymer sand screen, and slot eyelet is reasonable in design；Filter

The purpose of this utility model can be achieved by the following technical measures：
The through hole geo-polymer sand screen includes base tube, filter layer, and the filter layer is filtered for through hole geo-polymer
Layer, opens up slot eyelet on the base tube, the through hole geo-polymer filter layer is enclosed within base tube outer wall and cuts while covering completely
Slot apertures eye.
The purpose of this utility model can also be achieved by the following technical measures：
The through hole geo-polymer filter layer outer wall is cased with consolidation set, and the consolidation set is at least provided with one；It is described solid
Knot set is connected to through hole geo-polymer filter layer outer wall by the binding agent for heating.
The through hole geo-polymer filter layer top and bottom connect upper shield, lower shield, institute by binding agent respectively
State upper shield, lower shield to be welded on base tube.
The slot eyelet is laser slotted, and slot is uniformly distributed, the long 400-500mm of each seam, stitches width 3-5mm.
The base tube two ends open up screw thread, upper end connection top connection.
Body resistance-strengthening tablets are also set up on the base tube outer wall.
This utility model has the advantages that：
1st, base tube is designed with slot eyelet, stitches long 400-500mm, stitches width 3-5mm, to ensure the flow-passing surface on base tube surface
Product, to reduce the intensity of pressure in formation fluid recovery process.
2nd, sand screen filter layer adopts geology polymer material, comprcssive strength up to 9.0Mpa, apparent porosity up to 70%,
More than 800 DEG C of high temperature is resistant to, can be used for oil-water well sand control at various temperature, it is applied widely, and price is than conventional sand screen
It is cheap, be conducive to popularization and application.
3rd, many places consolidation set is set in filter layer outer wall, connects shield, geo-polymer filter layer in filter layer upper and lower side
Installation is connected by unconventional binding agent heating consolidation, and at consolidation, intensity is higher than geo-polymer filter layer intensity itself, protects
Card sand screen using effect.
