Abstract
Provided is a novel reducing sand screen overflows includes: top connection (b) (b) 1 (b) (b), center tube (b) (b) 2 (b) (b), the filter sand body (b) (b) 3 (b) (b), characterized by: novel reducing sand screen overflows's the last end screw thread connection of center tube (b) (b) 2 (b) (b) top connection (b) (b) 1 (b) (b), the lower extreme is equipped with the external screw thread, center tube (b) (b) 3 (b) (b) main part was equipped with discharge orifice (b) (b) G (b) (b), cross the outer filter sand body (b) (b) 3 (b) (b) (b) (the b) that be equipped with of discharge orifice (b) (b) G (b) (b), (B, ) (b) filter sand body (b) (b) 3 (b) (b) equipartition tapering hole (b) (b) Z (b) (b). The utility model is suitable for an oil field oil, gas well sand control, resin filter sand body intensity is high, the sand control dependable performance, it is big that the discharge orifice area is crossed to the tapering, and the flow resistance is little, long service life, in the extension sand control cycle, construction the job action is convenient, practices thrift the operating cost, and the sand screen overflows seal lock stopper back, and it is low backward to try the extrusion force, and the effect is obvious, increases oil well crude oil production. (B, )
Description
Technical field
This utility model relates to oil field oil, gas well down-hole sand-proof tool, a kind of novel stream reducing sand filtering tube excessively.
Background technology
At present oil field oil, gas well shake out is one of major issue of running in recovery process of oil.Can not get if shaked out effectively administering, oil, gas well shakes out will be increasingly severe, cause oil, gas well to can not get effectively and develop.Traditional anti-sand method mainly has following several: one is mechanical type sand control；Two is chemical formula sand control；Three is combined type sand control.The sand output well of Shengli Oil Field more than 90% 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, two be under 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 that crush resistance strength is low；Three is that effective drainage area is little, and flow resistance is big, it is impossible to meet oil field oil, gas well liquid loading needs.Especially after the blocking of sand screen flowing hole, reversely examination extruding force is high, and DeGrain causes oil well crude oil yield to decline.
Summary of the invention
The purpose of this utility model is aiming at the drawbacks described above that prior art exists, and design one is novel crosses stream reducing sand filtering tube.
This utility model is realized by following technical proposals:
This utility model includes: top connection, central canal, filter sand body.The threaded upper ends of the described novel central canal crossing stream reducing sand filtering tube is connected to top connection, and lower end is provided with external screw thread, and central canal main body is provided with flowing hole, and flowing hole is externally provided with filter sand body, the uniform tapered hole of filter sand body.
The above-mentioned novel filter sand body crossed in stream reducing sand filtering tube is formed by epoxy resin, gravel sand grains, coagulator high temperature sintering.
The beneficial effects of the utility model are: be applicable to oil field oil, gas well sand control, and resin filter sand body intensity is high, and sand control capability is reliable, tapering flowing hole area is big, flow resistance is little, and service life is long, extends the sand control cycle, construction operation is easy to operate, saving operating cost, after the blocking of sand screen flowing hole, reversely examination extruding force is low, effect is obvious, increases oil well crude oil yield.
Accompanying drawing explanation
Fig. 1-this utility model master is depending on partly cuing open structural representation.
In figure, 1. top connection, 2. central canal, 3. filter sand body；G. flowing hole, Z. tapered hole.
Detailed description of the invention
Below in conjunction with the accompanying drawings enforcement of the present utility model is further elaborated:
Novel stream reducing sand filtering tube of crossing is by top connection 1, central canal 2, filter sand body 3.The threaded upper ends of the described novel central canal 2 crossing stream reducing sand filtering tube is connected to top connection 1, and lower end is provided with external screw thread, and central canal 2 main body is provided with flowing hole G, flowing hole G and is externally provided with filter sand body 3, filter sand body 3 uniform tapered hole Z.
Operational approach
First, by design requirement sand washing to certain depth when oil, gas well operation, sand setting pocket is not less than 20m；
Secondly, check sleeve with the drift size gauge tool of dimension, meet the novel smooth G.I.H of stream reducing sand filtering tube excessively；
3rd, tubing string connects from bottom to top: plug (or temperature-sensing valve)+sand setting oil pipe+centralizer+novel stream reducing sand filtering tube+centralizer+oil pipe+hanging packer+oil pipe of crossing is to well head；
4th, by novel stream reducing sand filtering tube of crossing down between oil reservoir Lower and upper bounds, error+1m, grappling setting by packer requirement, gives up, and running speed is less than 30 pieces/hour, at the uniform velocity transfers and forbids percussion drill, drilling string not well braked.
Claims (2)
1. a novel stream reducing sand filtering tube excessively, including: top connection (1), central canal (2), filter sand body (3)；It is characterized in that: the threaded upper ends of the described novel central canal (2) crossing stream reducing sand filtering tube is connected to top connection (1), lower end is provided with external screw thread, central canal (2) main body is provided with flowing hole (G), and flowing hole (G) is externally provided with filter sand body (3), filter sand body (3) uniform tapered hole (Z).
Novel stream reducing sand filtering tube excessively the most according to claim 1, is characterized in that: described filter sand body (3) is formed by epoxy resin, gravel sand grains, coagulator high temperature sintering.
