Abstract
An oil well washing and sand washing tool is provided with a coupling, one end of the coupling is connected with a sand washing tool body, the other end of the coupling is in contact with a spraying head, a check block is arranged between the spraying head and the coupling, one end of the check block is connected with the upper end of the spraying head, the other end of the check block is in contact with a bearing, and therefore the spraying head and the coupling are connected together. A plurality of holes are formed in the upper portion of the spraying head, a hole is formed in the bottommost portion of the spraying head, three layers of holes are formed in the middle of the spraying head, according to two layers of holes, four holes are formed in each layer, in addition, two holes are formed in one layer, and the two holes are distributed in a point symmetry mode. According to the tool, the spraying head can rotate under the condition without extra power sources, the sand washing point of an oil well casing pipe is increased, the sand washing area of the oil well casing pipe is expanded, the washing preparation efficiency of the oil well casing pipe is improved.
Description
Technical field
The utility model relates to sand flushing tool, relates in particular to a kind of for oil well cleanup sand flushing tool.Belong to Offshore Engineering field.
Background technology
At present, in oil well, conventional sand flushing tool is provided with: sand flushing tool body, be arranged on the shower nozzle on sand flushing tool body, because shower nozzle is single-orifice type, that is: only opening bottom a hole.And single-orifice type sand flushing tool can not rotate the in the situation that of external power source, therefore, in use, easily cause in the time that oil well casing is rinsed, its sand washing point is more single, and sand washing area is narrow.
Utility model content
Main purpose of the present utility model is to overcome the above-mentioned shortcoming that prior art exists, and provide a kind of improved oil well cleanup sand flushing tool, it can be realized without extra at power source in the situation that, make shower nozzle rotation, not only increase the sand washing point to oil well casing, and, expand the sand washing area to oil well casing, improve the flushing of oil well casing has been prepared to efficiency.
The purpose of this utility model is realized by following technical scheme:
A kind of oil well cleanup sand flushing tool, is characterized in that: be provided with: a box cupling, and one end of this box cupling is connected with sand flushing tool body, and the other end of box cupling contacts with shower nozzle; Wherein, a block is installed between shower nozzle and box cupling, this block one end is connected with shower nozzle upper end, and the other end of block contacts with bearing, like this, just shower nozzle and box cupling 1 is linked together; The top of this shower nozzle is provided with several holes, and the below of shower nozzle is provided with a hole, and the middle part of shower nozzle is provided with three layers of hole, and wherein, two-layer hole is every layer and is provided with four holes, and in addition, one deck is provided with two holes, and two holes are that point symmetry distributes.
One end of described box cupling is to be connected with sand flushing tool body by tubing thread.
Each hole in the two-layer hole at described shower nozzle middle part is for being obliquely installed, and, by the uniform arrangement in the center of circle of shower nozzle.
The shape in two holes of described shower nozzle middle part one deck setting is " L " type.
Described block top is provided with oil sealing; The lower end of bearing is provided with O type circle.
The beneficial effects of the utility model: the utility model is owing to adopting technique scheme, it can be realized without extra at power source in the situation that, make shower nozzle rotation, not only increase the sand washing point to oil well casing, and, expand the sand washing area to oil well casing, improved the flushing of oil well casing is prepared to efficiency.
