Abstract

The utility model relates to a kind of servicing unit of oil exploitation, particularly relates to a kind of novel wire-wrapped screen.A kind of novel wire-wrapped screen, it has pipe joint, has vertical bracing frame below pipe joint, bracing frame is wound with some ring-like wrapping wires, has gap between wrapping wire, and the outside of wrapping wire is circular arc type, and the top and bottom of wrapping wire are all in downward-sloping shape.The utility model structure is simple, the outside of wrapping wire is that circular arc type can prevent sand grains from blocking, the top and bottom of wrapping wire all can make the sand grains of absorption easily come off when backwash in downward-sloping shape, the utility model increases the service life more than 1.6 times, plugging rate reduces by more than 30%, enhances productivity 40-45%.

Description

A kind of novel wire-wrapped screen

Technical field

The utility model relates to a kind of servicing unit of oil exploitation, particularly relates to a kind of novel wire-wrapped screen.

Background technology

Oil in oil reservoir is extracted out by oil exploitation process need, and containing sand grains in oil, for preventing from damaging oil pumper, needs to install wire-wrapped screen in oil pipe lower end.The wrapping wire top and bottom of existing wire-wrapped screen are the distribution of level, and there are two right-angled edges the outer end of wrapping wire.There is shortcomings in the design feature of existing wire-wrapped screen, is mainly manifested in: one is easy blocking, makes in use sand grains easily be adsorbed between wrapping wire rib; Two is not easily rinse, even if carry out backwash, sand grains also can firmly be stuck in difficult drop-off between wrapping wire rib; Three are reduction of pumping efficiency.A kind of novel wire-wrapped screen is inventors have developed for overcoming above-mentioned shortcoming.

Summary of the invention

Technical problem to be solved in the utility model is, a kind of technical scheme of novel wire-wrapped screen is provided for the deficiencies in the prior art, adopt the wire-wrapped screen of this technical scheme to have and prevent the characteristics such as blocking, easily flushing, improve pumping efficiency, extend the replacement cycle, reach the object reducing cost of production, enhance productivity.

The utility model is achieved in that a kind of novel wire-wrapped screen, and it has pipe joint, there is vertical bracing frame below pipe joint, bracing frame is wound with some ring-like wrapping wires, between wrapping wire, has gap, it is characterized in that, the outside of wrapping wire is circular arc type, and the top and bottom of wrapping wire are all in downward-sloping shape.

The beneficial effects of the utility model are, the utility model structure is simple, the outside of wrapping wire is that circular arc type can prevent sand grains from blocking, the top and bottom of wrapping wire all can make the sand grains of absorption easily come off when backwash in downward-sloping shape, the utility model increases the service life more than 1.6 times, plugging rate reduces by more than 30%, enhances productivity 40-45%.

Accompanying drawing explanation

Fig. 1 is structural representation of the present utility model.

Wherein, 1-pipe joint, 2-bracing frame, 3-gap, 4-wrapping wire.

Detailed description of the invention

Below in conjunction with accompanying drawing, concrete structure of the present utility model and principle are described further.

As shown in the figure, the novel wire-wrapped screen of one of the present utility model, it has pipe joint 1, vertical bracing frame 2 is had below pipe joint 1, bracing frame 2 is wound with some ring-like wrapping wires 4, has gap 3 between wrapping wire 4, it is characterized in that, the outside of wrapping wire 4 is circular arc type, and the top and bottom of wrapping wire 4 are all in downward-sloping shape.

Operating principle of the present utility model is such, pipe joint 1 of the present utility model is arranged on the bottom of oil well pump, can start oil pumping.When there being sand grains in oil, can be blocked on wrapping wire 4, and oil enters oil well pump from gap 3.Outside due to wrapping wire 4 is circular arc type, and sand grains is not easily stuck, and when oil well pump is when down moving, sand grains will split away off from screen casing.Meanwhile, the top and bottom of wrapping wire 4 all in downward-sloping shape, when have sand grains be adsorbed on above time, if when taking backwash means, sand grains be more prone to depart from screen casing.

Claims

1. a novel wire-wrapped screen, it has pipe joint, has vertical bracing frame below pipe joint, bracing frame is wound with some ring-like wrapping wires, has gap, it is characterized in that between wrapping wire, and the outside of wrapping wire is circular arc type, and the top and bottom of wrapping wire are all in downward-sloping shape.
