Abstract
The utility model discloses a coiled tubing rotating sand washing mill nozzle, which belongs to the technical field of coiled tubing sand washing, well washing and tube cleaning, wherein a rotating connector is connected with a nozzle, 1-inch automated multimedia terminal (AMMT) joints are arranged on the two ends of the rotating connector, the nozzle is a cylindrical mechanism, a tungsten alloy block is welded on the top end of the cylindrical mechanism, and the nozzle is provided with an a group holes, a b group holes and a c group holes, the a group holes and the b group holes are arranged on the circumference of the nozzle, the b group holes downwardly tilt 45 degrees with the horizontal direction, and the c group holes are arranged on the top end of the nozzle. The coiled tubing rotating sand washing mill nozzle reduces construction period of sand washing operation, reduces construction procedure, reduces labor strength by using coiled tubing construction for the sand washing operation, is high in sand washing efficiency of nitrogen, and is excellent in cleaning effect of bridge over and sand carrying capacity. When the coiled tubing rotating sand washing mill nozzle works, jet flow stereoscopically washes sand in all directions, and has the effect of milling a plug surface, and increases action area and sand carrying capacity through rotating operation. The coiled tubing rotating sand washing mill nozzle is safe and reliable, convenient to connect and light in quality, and can complete the processes of well washing, sand washing and tube cleaning at a time.
Description
Technical field
The utility model relates to a kind of coiled tubing rotation sand washing milling shower nozzle, belongs to coiled tubing sand washing, well-flushing, siphunculus technical field.
Background technology
In the sand washing construction, first lower tubular column is visited behind the Shamian Island position and to be carried out the sand washing operation being lowered to sand-flushing pipe column, during every lower 1/3 tubing string length, need pressure testing whether to check seepage, qualified rear continuation running string, be connected with well head by pump truck to adopt and just washing or backwash process is carried out the sand washing operation.Trip out sand-flushing pipe column after sand washing process completes and be lowered to flow string according to construction technology, increased a large amount of construction periods and labour intensity.The current that pump truck is squeezed into certain pressure on the other hand can not effectively destroy the oil of consolidation, the sand plug layer that sand mixes, and need to pump into a large amount of water and progressively permeate sand plug and carry sand grains and complete the sand washing operation.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides a kind of coiled tubing rotation sand washing milling shower nozzle.
A kind of coiled tubing rotation sand washing milling shower nozzle, rotary connector connects shower nozzle; The rotary connector two ends are 1 cun AMMT button-type; , there are a group hole, b group hole and c group hole in the column type mechanism that shower nozzle is a top welding tungsten steel alloy piece; A group hole, b organize the circumference of hole at shower nozzle, downward-sloping 45 degree of b group hole and horizontal direction, and c group hole is positioned at the top of shower nozzle.
The utility model has the advantages that: continuous oil pipe operation shortens the sand washing job execution cycle, reduces working procedure; The sand washing operation is used the coiled tubing construction to alleviate larger labour intensity; Nitrogen sand washing operating efficiency is high, and cleaning sand plug, silt carrying capacity is effective; During the shower nozzle operation, the sand washing of injection stream omnibearing stereo, and there is the effect of milling plug face, rotary operation has strengthened active area and the prop-carrying capacity of jet; Safe and reliable, quality easy to connect is light, but one-stop operation completes well-flushing, sand washing, siphunculus operation.
The accompanying drawing explanation
When considered in conjunction with the accompanying drawings, by the detailed description with reference to following, can more completely understand better the utility model and easily learn wherein many advantages of following, but accompanying drawing described herein is used to provide further understanding of the present utility model, form a part of the present utility model, schematic description and description of the present utility model, for explaining the utility model, does not form improper restriction of the present utility model, as schemed wherein:
Fig. 1 is structural representation of the present utility model.
Below in conjunction with drawings and Examples, the utility model is further illustrated.
The specific embodiment
Obviously, the many modifications and variations that those skilled in the art do based on aim of the present utility model belong to protection domain of the present utility model.
Embodiment 1: as shown in Figure 1, a kind of coiled tubing rotation sand washing milling shower nozzle, rotary connector 1 connects shower nozzle 2; Rotary connector 1 two ends are 1 cun AMMT button-type, for connecting coiled tubing and shower nozzle;
, there are a group hole 3, b group hole 4 and c group hole 5 in the column type mechanism that shower nozzle 2 is a top welding tungsten steel alloy piece; A group hole 3, b organize the circumference of hole 4 at shower nozzle 2, b group hole 4 and downward-sloping 45 degree of horizontal direction, and c group hole 5 is positioned at the top of shower nozzle 2.
Shower nozzle 2 is according to being divided into three groups of not spray-holes of same-action on function, and a group hole 3 injection directions are level, for cleaning tube wall direction dirt oil-sand.B group hole 4 and downward-sloping 45 degree of horizontal direction, c organizes 5 holes and is positioned at top, organizing hole 3, b group hole 4 and 5 positions, c group hole by a forms, jet forms the work plane of stereoscopic and omnibearing, sand face by top milling and nitrogen high speed impact consolidation, form the comprehensive cleaning tube wall of spiral status and sand plug, the factors such as variable speed, inequality and the deviation of directivity by fluid cause jet to have certain whirlpool, rely on the absorption affinity of whirlpool to increase prop-carrying capacity, finally by gaseous disk, screw on to rise and discharge from annular space.
As mentioned above, embodiment of the present utility model is explained, but, as long as not breaking away from fact inventive point of the present utility model and effect can have a lot of distortion, this will be readily apparent to persons skilled in the art.Therefore, within such variation also all is included in protection domain of the present utility model.
