Abstract
The utility model relates to a ceramic sand screening pipe which is characterized in that the shape of the ceramic sand screening pipe is a cylinder stacked by a plurality of cylindrical sections made of round ceramic slices, wherein the thickness of each round ceramic slice is from 0.5mm to 1.5mm and the height of each cylindrical section is from 10mm to 1000mm; each round ceramic slice is formed by ordered arrangement of a plurality of trapezoidal or parallelogrammic ceramic slices, wherein the intervals between slices are from 0.1mm to 0.35mm. This sand screening pipe has the advantages of corrosion proof, uneasiness in scale formation, good sand screening effect and long service life.
Description
One, technical field
The utility model relates to ceramic sand screen used in a kind of oil field development.
Two, background technology
At present development late stage has been arrived in the oil field, and stratum energy can not lean on self pressure that crude oil is given rise to ground, has all adopted the mode of recovering the oil of forcing, as water filling, annotate vapour, polymer injection and mechanical oil recovery.The easy silt particle with the stratum of forcing to recover the oil takes in the layout of oil and gas gathering system of ground.Stop up in flow process or the wearing and tearing flow process equipment and measuring instrument or pile up shaft bottom sand and bury oil pipe, make workover or scrap, have a strong impact on the oil field ordinary production.
For solving this technical barrier, generally adopt anti-sand process technology to solve, the down-hole mainly is to adopt sand screen.Used sand screen mainly is steel wire wind pipe, Fu's film sandpipe etc.These sand screens can not satisfy the needs of oil field development, and different oil field blocks have different rock stratum, and different silt particle particle diameters so require plurality of specifications, can form the sand screen of series.
Three, summary of the invention
The purpose of this utility model is to provide a kind of ceramic sand screen for the sand control technology.
The technical solution of the utility model realizes in the following manner:
The pottery sand screen is characterised in that it is shaped as cylindrical that the cylindrical section made by some ceramic circle sheets is formed by stacking, and the thickness of every ceramic circle sheet is 0.5～1.5mm, the height 10～1000mm of each cylindrical section; Every ceramic sheet is that some orderly arrangements of potsherds trapezoidal or parallelogram form, and the gap is 0.1～0.35mm between every.
That the utility model compared with prior art has is corrosion-resistant, be not easy fouling, filter sand is effective, the advantage of long service life.
Four, description of drawings
Fig. 1-structural scheme of mechanism of the present utility model;
The structural representation of Fig. 2-ceramic circle sheet;
The structure partial cut-away view of Fig. 3-ceramic cylinder section.
Five, embodiment
For further disclosing the novel technical scheme of this use, be described in detail by enforcement below in conjunction with Figure of description:
As Fig. 1, Fig. 2, shown in Figure 3:
Pottery sand screen 3 be shaped as cylindrical that cylindrical section 2 that some ceramic circle sheets 1 are fired into is formed by stacking.The thickness of every ceramic circle sheet is 0.5～0.3mm, and the height of each cylindrical section is 10～1000mm, and every ceramic circle sheet is to be arranged in order by some potsherds trapezoidal or parallelogram to form.The gap is 0.1～0.35mm between every.
Pottery sand screen production technology is divided following several steps:
1, is pressed into the mould of ceramic circle sheet with low-melting plastics or lead or tin.
2, mould is enclosed within on the cylinder that is fired into refractory material.Put a mould and press one deck pottery mud, successively stack, its height is made according to design height between 10mm～1000mm.
3, putting the cylindrical section of making into stove and accessory fires.In sintering procedure, the mould fusing becomes gas or liquid and flows out.Firing more than 1000 ℃ the ceramic cylinder section promptly burns till.
4, the ceramic cylinder section is piled up to becoming needed ceramic sand screen, be bonded together with high-temperature-resistant adhesive between each ceramic cylinder section.
