Description
Technical field
The utility model relates to oil recovery field, is specifically related to a kind of drilling rod sand washing crossover sub.
Background technology
In field produces, during heavy repair task, drilling rod is one of the most frequently used instrument, and to utilize drilling rod to implement sand washing operation be also the conventional operation in daily heavy repair task.Under general condition, the drilling assembly of overhaul drilling rod sand washing is: the one, and sand-washing pen point, drilling rod and kelly bar; The 2nd, sand-washing pen point, drilling rod, drilling rod and oil pipe variable buckle joint, union variable buckle joint, sand washing union head and sand washing elbow.The first is sand washing combination conventional in overhaul well workover, and program during this drilling assembly sand washing is that the length of kelly bar is swept away, after well-flushing, trip out kelly bar, after be lowered to a drill pipe joint, at connection side's drilling rod, implement sand washing, such process completes changes single general 5min; And the second sand washing mode combines, need on drill pipe coupling, connect two variable buckle joints, drilling rod button-type is converted to conventional sand washing union joint, just can carry out sand washing, in this also there is drawback in combination, because crossover sub is more, reduced the distance between hook block and sand washing elbow, cause space not or change sledgehammer when single and pound union inconvenience, and joint is more, dangerous hidden danger.
Utility model content
The utility model provides a kind of drilling rod sand washing crossover sub, and when solving existing heavy repair task, crossover sub is more, has reduced the distance between hook block and sand washing elbow, and maintenance is inconvenient, the problem that potential safety hazard is many.
For this reason, the utility model proposes a kind of drilling rod sand washing crossover sub, described drilling rod sand washing crossover sub comprises: drilling rod buckle joint, the sand washing joint body being connected with described drilling rod buckle joint and the flat button union joint being connected with described sand washing joint body, wherein, described drilling rod buckle joint and described flat button union joint lay respectively at the two ends of described sand washing joint body, and described drilling rod buckle joint, described sand washing joint body and described flat button union joint are integral type structure.
Further, described drilling rod buckle joint is 2
7/8drilling rod buckle joint.
Further, the tubular type that described sand washing joint body is φ 105mm.
Further, described flat button union joint is the tubular joint of φ 60mm.
Further, described drilling rod buckle joint is cone shaped.
Further, described drilling rod buckle joint connects sand washing drilling rod.
Further, described flat button union joint connects sand washing union head.
Further, described sand washing union head connects sand washing elbow and hose.
Further, described hose is connected to cementing truck or slush pump, and described sand washing drilling rod is connected to sand-washing pen point.
Further, the total length of described drilling rod buckle joint, described sand washing joint body and described flat button union joint is 15cm.
The beneficial effects of the utility model have:
1, whole joint integrated design, turning completes, simple to operate during on-the-spot sand washing, safe and efficient;
2, adopt this joint, can guarantee to adopt the positive and negative circulation sand washing of drilling rod requirement, and sand washing elbow and hook block ensure certain space and distance, avoided the danger of hook block press-bending variable buckle or sand washing elbow.
3,, in the time of can reducing the sand washing of field by using drilling rod, need the drawback of coupling adapter, and simplicity of design moderate length, can meet the operating distance between common suspension ring and elevator.
Accompanying drawing explanation
Fig. 1 is the structural representation of drilling rod sand washing crossover sub of the present utility model.
The specific embodiment
For technical characterictic of the present utility model, object and effect being had more clearly, understand, now contrast accompanying drawing the specific embodiment of the present utility model is described.
As shown in Figure 1, drilling rod sand washing crossover sub comprises: drilling rod buckle joint 1, the sand washing joint body 2 being connected with described drilling rod buckle joint and the flat button union joint 3 being connected with described sand washing joint body, wherein, described drilling rod buckle joint 1 and described flat button union joint 3 lay respectively at the two ends of described sand washing joint body 2, and described drilling rod buckle joint 1, described sand washing joint body 2 and described flat button union joint 3 are integral type structure.Whole joint integrated design, easy to connect, guaranteed the positive and negative circulation sand washing of overhaul drilling rod requirement.Further, described drilling rod buckle joint is 2 of routine
7/8drilling rod buckle joint, the pin thread that described drilling rod buckle joint is cone shaped, described drilling rod buckle joint connects sand washing drilling rod.
Further, described sand washing joint body is the tubular type of φ 105mm, is convenient to the upper and lower latus rectum of overhaul hydraulic tongs and automatically goes up shackle.Further, described flat button union joint is the tubular joint of φ 60mm, this flat button union joint is pin thread, for directly connecting sand washing union head and sand washing elbow, such design can reduce the distance between hook block and sand washing elbow, be convenient to normally to remove sand washing and change the single union of pounding operate, and such sand washing combination is, reduce the tie point of screw thread, reduced the dangerous point source at overhaul well workover scene.
Described flat button union joint connects sand washing union head.Described sand washing drilling rod is connected to sand-washing pen point.Described sand washing union head connects sand washing elbow and hose.Described hose is connected to cementing truck or slush pump, sets up oil pipe circulation, completes sand washing operation.The two ends of whole drilling rod sand washing crossover sub connect sand-washing pen point, sand washing elbow and hose, form a sand washing drill string, by elevator, hang whole sand washing drill string, by hook block, raise and decentralize sand washing drill string.
The total length of described drilling rod buckle joint 1, described sand washing joint body 2 and described flat button union joint 3 is 15cm.Whole drilling rod sand washing crossover sub simplicity of design, moderate length, can meet the operating distance between common suspension ring and elevator.
The utility model is achieved in that
When adopting the direct sand washing of drilling rod (not adopting under kelly bar sand washing condition), connect sand-washing pen point and drilling rod, normal lower boring, when down to the above 3-5m of sand face, drilling rod buckle joint 1 is connected in to drill pipe coupling place, and flat button union joint 3 connects conventional sand washing union head, and connects sand washing elbow and hose, normal turn on pump circulation, can complete positive sand washing and the operation of recoil sand.Adopt this kind of mode, in the time of can saving the sand washing of overhaul drilling rod, change the single time, in the time of needn't be as original overhaul kelly bar sand washing, rush the complicated procedures of one of piece, and next root; And without connecting 2 variable buckle joints, avoided the generation that distance between suspension ring and sand washing elbow is inadequate, cause hook block press-bending joint accident.
The foregoing is only the schematic specific embodiment of the utility model, not in order to limit scope of the present utility model.For each ingredient of the present utility model can mutually combine under the condition of not conflicting; any those skilled in the art; do not depart from equivalent variations and the modification of having done under the prerequisite of design of the present utility model and principle, all should belong to the scope of the utility model protection.
