Abstract
Provide is an eccentric water distributor. The eccentric water distributor comprises an upper connecting body (1) and a lower connecting body (2), wherein an outer sleeve (3) is connected at the lower end of the upper connecting body (1) in a threaded mode, an eccentric body (5) is connected at the lower end of the outer sleeve (3) in a threaded mode, a guide body (4) is arranged in the outer sleeve (3), a nib at the upper end of the guide body (4) extends into the upper connecting body (1), the eccentric body (5) is connected at the lower end of the guide body (4) through a screw (6), and the lower connecting body (2) is connected with the lower end of the eccentric body (5) in a threaded mode. The eccentric water distributor has the functions of scale prevention and scale sand deposition prevention, and is beneficial for the conducting of testing work.
Description
Technical field
The utility model relates to downhole tool used in the oil extraction in oil field field, especially eccentric injection mandrel.
Background technology
The oil field enters secondary phase of oil production, usually recover the oil with the method for water filling, injection well downhole flow regulator is a kind of downhole tool commonly used in the oil-extracting and water-injecting process, at present, along with updating of injection well testing technique, most of instruments have realized hanging in the oil pipe survey mode, and the part-structure that old underground water distribution device has does not re-use, the many impact tests of the fouling point that has etc.; Other present employed eccentric injection mandrel, in the process of well-flushing, guide way and annular space overcoat often have the accumulation of down-hole dirt, sand, produce vibration during test it is dropped out, and it is unfavorable to testing to stop up water nozzle.
Summary of the invention
In order to overcome the deficiency that exists in the background technology, the utility model provides a kind of eccentric injection mandrel, and this eccentric injection mandrel has been optimized overall structure, prevents that effectively the accumulation of dirt, sand is on the impact of test.
The technical solution of the utility model is: this eccentric injection mandrel comprises connector and lower connector, upper connector lower end screw thread is connected with overcoat, overcoat lower end screw thread is connected with eccentric body, be provided with guide way in the overcoat, the nib of guide way upper end extends in the connector, the guide way lower end is connected with eccentric body by screw, and eccentric body lower end screw thread is connected with lower connector.
The beneficial effect that the utlity model has is: move on on this lower nib with injection well downhole flow regulator guide way above, become one with guide way, during test the rotation of instrument direction more flexible, remove " gaily decorated basket " and reduce fouling point, and accordingly instrument is done weak point, be conducive to test.The open slot of guide way is close to the overcoat of housing, so that the impurity in the overcoat space of guide way and housing can't drop out.The use of Novel eccentric water distributing apparatus has solved the impact on testing because of injection well downhole flow regulator fouling and well-flushing deposition dirt, has improved testing efficiency, has reduced post workman's labour intensity, has higher economic benefit and social benefit.
Description of drawings:
Accompanying drawing 1 is structure sectional view of the present utility model;
Accompanying drawing 2 is the sectional views at I place in the accompanying drawing 1.
The upper connector of 1-among the figure, connector under the 2-, 3-overcoat, 4-guide way, 5-eccentric body, 6-screw.
The specific embodiment:
Below in conjunction with accompanying drawing will the utility model is described in further detail:
By shown in Figure 1, this eccentric injection mandrel comprises connector 1 and lower connector 2, and upper connector 1 lower end screw thread is connected with overcoat 3, overcoat 3 lower end screw threads are connected with eccentric body 5, be provided with guide way 4 in the overcoat 3, the guide way 4 open slot edge on axially closely links to each other with overcoat 3, and dirty slag can't be dropped out.The nib of guide way 4 upper ends extends in the connector 1 and is provided with lower nib, and guide way 4 lower ends are connected with eccentric body 5 by screw 6, and eccentric body 5 lower end screw threads are connected with lower connector 2.
Claims (1)
