The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail:
As Fig. 1, shown in 2, the two-stage sand control screen that is used for oil-gas mining of the present utility model, comprise parent tube 1, parent tube 1 is provided with two sections overcurrent eyelet 6 zones, be respectively equipped with connection external screw thread 4 at parent tube 1 outer wall two ends, wherein be connected with the box cupling 5 that has internal thread on the end external screw thread 4, a plurality of parent tubes 1 are joined end to end form the sand control pipe of certain-length, on the outer wall of parent tube 1, be with sand control and cross filter ruffle with two sections overcurrent eyelets, 6 regional corresponding positions, sand control is crossed the end ring 3 that filter ruffle comprises tubular filter plate 2 and is fixed on tubular filter plate 2 two ends, the external surface of tubular filter plate 2 is provided with the hole countersunk opening 7 that a plurality of punching presses form, be formed with circulation slit 9 on the hole wall of opening 7, the end ring 3 at two ends is fixed on the parent tube 1.
The external diameter of described end ring 3 is identical with the external diameter of tubular filter plate 2.It is more bigger than the external diameter of parent tube 1 that described sand control is crossed the internal diameter of filter ruffle, makes sand control cross filter ruffle and parent tube 1 is combined closely.That is to say that the two ends of tubular filter plate 2 are fixing with end ring 3 by welding, parent tube 1 is welded as a whole by end ring 3 with tubular filter plate 2.The external diameter of end ring 3 is identical with the external diameter that sand control is crossed filter ruffle, so that the external diameter of this product is littler, on-the-spot adaptive capacity is strengthened greatly.
Described opening 7 is the longitudinal section bridge-type counterbore of shape in echelon, opening 7 length: 8-15mm, width: 2-5mm; Circulation slit 9 width: 0.1mm-1.5mm.
Described tubular filter plate 2 is stainless steel or carbon steel, and its thickness is 1.0 to 2.5mm.
Below the utility model is elaborated:
Technical data as preferential parent tube:
Outside dimension series is: 60.3mm, 73.0mm, 88.9mm, 101.6mm, 114.3mm, 127.0mm, 139.7mm, 168.3mm, 177.8mm;
Parent tube grade of steel series: J55, K55, N80, L80, P110,13Cr;
Overcurrent eye diameter: 8-15mm;
Overcurrent perforation density: 150-700 hole/rice.
As shown in Figure 2, be the partial perspective view of tubular filter plate in the utility model, the tubular filter plate is that spiral forming does not also weld the preceding architectural feature of typing as seen from the figure.Described filter plate preferably material is carbon steel and 304, and the stainless steel material of 316L, its thickness are 1.0mm to 2.5mm.Before spiral forming, on its external surface 202, be provided with a plurality of hole countersunk openings 7 by forming towards its inner surface 201 direction punching presses, the bottom 8 in opening 7 holes is to recessed, and is promptly recessed to inner surface 201 directions.On the hole wall of described opening 7, be provided with the hydrocarbon fluids circulation slit 9 of proper width, cross the inside of filter ruffle and, change the hydrocarbon fluids flow direction simultaneously, reduce flow velocity, alleviate fluid erosion the sandstone isolation so that hydrocarbon fluids enters sand control.
In conjunction with installation drawing shown in Figure 1 as seen, wherein said sand control cross filter ruffle for by filter plate through along inner surface 201 helical bucklings of filter plate to form caliber, because employing spiral welding procedure both had been beneficial to the cost that saves material, be convenient to large-scale processing again, also have advantages of high strength simultaneously.
Wherein preferably: opening 7 is the longitudinal section bridge-type counterbore of shape in echelon, described filter plate is before spiral forming, be provided with the hole countersunk opening that a plurality of punching presses form on its outer surface, on the hole wall of opening, be provided with the circulation slit of proper width, these fluid flow slit 9 width can accurately be controlled by punching press, it stitches wide can the design according to the particle size of oil gas well reservoir sand, both can play the effect that stops that reservoir sand enters, and can be used as the output passage of oil gas again.The preferred size that the utility model proposes is described opening length: 8-15mm, width: 2-5mm, and described circulation gap width: 0.1mm-1.5mm is to adapt to different underground sandstone sizes.
Sand control is crossed filter ruffle: the bridge-type counterbore of the about 25mm part in tubular filter plate 2 two ends is flattened by hydraulic action to recessed base; Respectively end ring 3 is inserted in the both ends of tubular filter 2, enters about 25mm, weldering is one then, forms sand control and crosses filter ruffle; Then sand control is crossed filter ruffle and be inserted in the overcurrent eyelet 6 regional overcurrent eyelets 6 that also cover in fully on the parent tube 1 step by step, at last end ring 3 and parent tube 1 weldering are one.
In sum, content of the present utility model is not limited in the above-described embodiment, knowledgeable people in the same area can propose other embodiment easily within technological guidance's thought of the present utility model, but this embodiment is included within the scope of the present utility model.
