Abstract
A kind of neo-epoxy resin sand screen, including: central canal (1), filter sand body (2), pin (3)；It is characterized in that: central canal (1) upper/lower terminal of described neo-epoxy resin sand screen is provided with external screw thread, middle part is provided with flowing hole (G), central canal (1) is externally provided with tubular ring epoxy resins filter sand body (2), is provided with pin (3) between gap and epoxy resin filter sand body (2) of the upper flowing hole (G) of central canal (1).This utility model is applicable to oilfield and shakes out the sand well mechanical sand control of median grain diameter 0.07～0.1mm, central canal flowing hole area of passage is big, and flow resistance is little, and central canal couples with filter sand body pin, comprcssive strength 10Mpa, permeability 140 square micron, porosity 38%, sand controlling result is good, service life is long, extend the sand control cycle, save operating cost, increase crude output.
Description
Technical field
This utility model relates to oilfield down-hole sand-proof tool, specifically a kind of neo-epoxy resin sand screen.
Background technology
At present oilfield shakes out is one of major issue of running in recovery process of oil.Traditional anti-sand method master
Have following several: one is mechanical type sand control；Two is chemical formula sand control；Three is combined type sand control.Shengli Oil Field more than 90%
Sand output well uses mechanical type sand control, and mechanical type sand control is divided into again two big classes；One is pre-fill sand prevention tubing string sand block, under two are
Enter sand control pipe and carry out filling again.Above-mentioned sand control there is problems in that one is antidetonation, drop resistant ability；Two is crush resistance strength
Low；Three is that effective area of passage is little, and flow resistance is big, it is impossible to meet oilfield crude oil production needs.
Summary of the invention
The purpose of this utility model is aiming at the drawbacks described above that prior art exists, design a kind of neo-epoxy resin filter
Sandpipe.
The purpose of this utility model is realized by following technical proposals:
This utility model includes: central canal, filter sand body, pin；It is characterized in that: described neo-epoxy resin sand screen
Central canal upper/lower terminal is provided with external screw thread, and middle part is provided with flowing hole, and central canal is externally provided with tubular ring epoxy resins filter sand body, in
It is provided with pin between gap and the epoxy resin filter sand body of flowing hole on heart pipe.
Flowing hole in above-mentioned neo-epoxy resin sand screen is rectangle round end hole.
Filter sand body in above-mentioned neo-epoxy resin sand screen is that epoxy resin has certain hole with cementing the forming of quartz sand
The mix cylinder of gap.
The beneficial effects of the utility model are: be applicable to that oilfield shakes out median grain diameter 0.07～0.1mm goes out sand oil
Well mechanical sand control, central canal flowing hole area of passage is big, and flow resistance is little, and central canal couples with filter sand body pin, comprcssive strength
10Mpa, permeability 140 square micron, porosity 38%, sand controlling result is good, and service life is long, extends the sand control cycle, saves
Operating cost, increases crude output.
Accompanying drawing explanation
Fig. 1-this utility model master is depending on partly cuing open structural representation.
In figure, 1. central canal, 2. filter sand body, 3. pin；G. flowing hole.
Detailed description of the invention
Below in conjunction with the accompanying drawings enforcement of the present utility model is further elaborated:
Neo-epoxy resin sand screen is by central canal 1, filter sand body 2, pin 3.Described neo-epoxy resin sand screen
Central canal 1 upper/lower terminal is provided with external screw thread, and middle part is provided with rectangle round end flowing hole G, and central canal 1 is externally provided with tubular ring oxygen tree
Fat filter sand body 2, is provided with pin 3 between gap and the epoxy resin filter sand body 2 of flowing hole G on central canal 1.
Operational approach
1., by design requirement sand washing to certain depth when oil, gas well operation, sand setting pocket is not less than 20m；
2. check sleeve with the drift size gauge tool of dimension, meet the smooth G.I.H of neo-epoxy resin sand screen；
3. tubing string connects from bottom to top: plug+neo-epoxy resin considers sandpipe+oil pipe+safety joint+packer+loss
Joint+work string；
By neo-epoxy resin sand screen down between oil reservoir Lower and upper bounds, error+1m, anchor setting by packer requirement
Determining, give up, running speed is less than 30 pieces/hour, at the uniform velocity transfers and forbids percussion drill, drilling string not well braked.
Claims (3)
