Abstract
The utility model relates to a cage-shaped sand-proof screening pipe for a water well used for industrial and civil water wells. The cage-shaped sand-proof screening pipe for a water well used for industrial and civil water wells is composed of a basal pipe (1), a screen net (2), a steel bar (3), and a steel wire (4), wherein, the steel bar (3) and the steel wire (4) are winded and welded into a steel cage. Stainless steel is adopted by the screen net (2), the steel bar (3), and the steel wire (4). The sand-proof effect, the mechanical intensity, and the corrosion resistance of the cage-shaped sand-proof screening pipe for a water well used for industrial and civil water wells are all greatly enhanced due to the improvement of a structure, a material, and processing conditions. The cage-shaped sand-proof screening pipe for a water well used for industrial and civil water wells can be used for ensuring that the service life of a water well is extended, the running of the water well is favorable for a long time, well repair times are reduced, and water well repair and renovating cost is saved.
Description
The utility model relates to a kind of anti-intensity device of sand control that is used for industry and civilian well, particularly a kind of cage shape well sand control screen that plays the filter pipe effect.
At present, the filter pipe that well uses adopts pad muscle, bag net, wrapping wire structure usually, generally all processes at the water well drilling scene.Owing to structural reason, add the restriction that is subjected to processing conditions and material, the specification and the skewness of this kind filter pipe hole, thereby sand controlling result is poor, mechanical strength is low, causes steel mesh to break during pumping easily.Because corrosion resistance is poor, the wrapping wire iron wire is perishable, and the time one for a long time will fracture of wire, shake out, and is unfavorable for the operation of well long-term production.
The purpose of this utility model is to provide that a kind of mechanical strength height, corrosion resistance are good, even pore distribution, filter pipe--cage shape well sand control screen that sand controlling result is good.
The utility model is to realize like this.This kind sand control screen is made up of parent tube, screen cloth, reinforcing bar, steel wire, and its architectural feature is, is surrounded by one deck screen cloth on the parent tube body, and the screen cloth spaced around is provided with many reinforcing bars, and its outer boxing has steel wire, makes the steel cage, and steel cage two ends are fixed on the parent tube.Because screen cloth, reinforcing bar and the steel wire of this sand control screen all adopt stainless steel, and adopt special mechanical equipment processing, thereby its mechanical strength and corrosion resistance are all increased, and can guarantee screen casing hole specification, be evenly distributed, obtain good sand controlling result.
The utility model is because the improvement of structure, material and processing conditions, make its sand controlling result and mechanical strength, corrosion resistance all obtain bigger raising, utilize this kind sand control screen can guarantee that well prolongs application life, long-time running is good, reduce the well workover number of times, save well maintenance and update cost.
Fig. 1, Fig. 2 are structural representation of the present utility model and vertical view.
Fig. 3, Fig. 4 are the schematic diagram and the vertical view of the another kind of form of structure of the utility model.
Below in conjunction with accompanying drawing enforcement of the present utility model is illustrated.
As shown in Figure 1, parent tube 1 external diameter ∮ 117.8mm evenly is drilled with some ∮ 16mm eyelets by 25% of body surface area, and upper and lower end is respectively equipped with negative thread and pin thread.Screen cloth 2 adopts 40 order stainless (steel) wires.Reinforcing bar 3 adopts the stainless steel rebar of diameter 5mm, and steel wire 4 adopts wide for 1.5-2mm, cross section are trapezoidal stainless steel wire, wrapping wire spacing 0.25-0.35mm, and the Rotating Stainless Steel Cage external diameter of being made by reinforcing bar 3 and steel wire 4 boxings is 194mm.The most of modular constructions of another kind of form of structure shown in Fig. 3,4 are identical with Fig. 1, just are filled with the quartz sand 5 of particle diameter 1-2mm in the annular space between parent tube 1, screen cloth 2 and the steel cage made by reinforcing bar 3 and steel wire welded, and at this moment, steel cage external diameter is 235mm.Above-mentioned two kinds of form of structure cage shape sand control screens adopt when the water layer of Different Strata condition respectively.
Claims (2)
1. cage shape well sand control screen, form by parent tube (1), screen cloth (2), reinforcing bar (3), steel wire (4), it is characterized in that: be surrounded by one deck screen cloth (2) on parent tube (1) body, screen cloth (2) spaced around is provided with many reinforcing bars (3), its outer boxing has steel wire (4), make the steel cage, steel cage two ends are fixed on the parent tube (1); The another kind of form of structure of this screen casing is to be filled with quartz sand (5) in the annular space between parent tube (1), screen cloth (2) and the steel cage made by reinforcing bar (3) and steel wire (4) boxing.
2. cage shape well sand control screen according to claim 1 is characterized in that, the screen cloth of this sand control screen (2), reinforcing bar (3) and steel wire (4) all adopt stainless steel to make.
