Abstract

The utility model provides a horizontal well sand washing sprayer belongs to a oil field production apparatus, and it has the top connection, is fixed with the center tube below the top connection, and there is rubber packing cup in the center tube upper portion outside, and the center tube lower extreme is fixed together with the injector head that the olive is spherical, and the water hole in the injector head communicates with each other with the center tube inner chamber, and a plurality of jet orifices that are the distribution of scattering form on the injector head communicate with each other with the water hole. This kind of horizontal well sand washing sprayer, rational in infrastructure, during the use, sand washing liquid sprays in the pit shaft through a plurality of jet orifices. Because the pumping pressure the during sand washing and the throttling action of jet orifice for the spraying pressure increases, thereby breaks up the grit in shaft bottom, and smallclothes junks such as garrulous rubber are also rush out, and the grit of horizontal segment deposition phenomenon can not appear yet under the effect of jet orifice spun liquid, and sand washing liquid carries ground with grit and smallclothes junk, and the sand washing is effectual.

Description

Horizontal well sand washing injector
Technical field
The utility model provides a kind of field produces apparatus, especially a kind of injector for horizontal well sand washing.
Background technology
In oil extraction in oil field production process, carry out sand washing operation to horizontal well. At present, in the time carrying out horizontal well sand washing, be prone to sand depositional phenomenon at horizontal segment, cause sand can not go out ground completely. Because existing emitter construction reasonability is poor, solid or while having the small falling objects such as broken rubber at sand face, can cause sand washing to be rushed motionless, affect construction effect.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of horizontal well sand washing injector, to improve sand washing effect.
The utility model is to realize like this, horizontal well sand washing injector, it has top connection, below top connection, be fixed with central tube, central tube upper outside has rubber cup, the injector head of central tube lower end and rugby shape is fixed together, and the water hole in injector head communicates with central tube inner chamber, and the multiple spray-holes that are dispersion shape distribution on injector head communicate with water hole.
The horizontal well sand washing injector that adopts said structure, rational in infrastructure, when use, sand cleaning fluid is injected in pit shaft through multiple spray-holes. Pump pressure during due to sand washing and the throttling action of spray-hole, expulsion pressure is increased, thereby the sand in shaft bottom is broken up, the small falling objects such as broken rubber are also rushed out, the sand of horizontal segment also there will not be depositional phenomenon under the effect of the liquid of spray-hole ejection, sand and small falling object are carried to ground by sand cleaning fluid, and sand washing is effective.
Brief description of the drawings
Fig. 1 is the schematic diagram of the utility model structure.
Detailed description of the invention
The embodiment providing below in conjunction with accompanying drawing further illustrates the concrete structure of utility model.
As shown in drawings, the horizontal well sand washing injector of the utility model, it has top connection 1, below top connection, be fixed with central tube 3, central tube upper outside has rubber cup 2, the injector head 4 of central tube lower end and rugby shape is fixed together, and the water hole 5 in injector head communicates with central tube inner chamber, and the multiple spray-holes 6 that are dispersion shape distribution on injector head communicate with water hole.
When use, top connection is connected to below working string, and whole injector is lowered to horizontal well sand washing job position with working string. Sand cleaning fluid enters central tube, and the stepping of going forward side by side enters the water hole in injector head, finally, from spray-hole ejection, carries out sand washing operation. Due to the throttling action of pump pressure and spray-hole, expulsion pressure increases, solid sand face or have the small falling objects such as broken rubber to be rushed. Space between rubber cup blocked center pipe and working string, prevents that sand cleaning fluid from flowing in this space. After sand washing, the sand cleaning fluid that is being mingled with sand, small falling object enters the space between working string and sleeve pipe, and flows upward to outside well. So repeatedly, finally complete sand washing operation.
