Abstract
At present, when oil field at home is with eccentric injection mandrel seperated layer water injection, the blanking plug in injection well downhole flow regulator is needed to pull out, owing to containing sand setting and foreign material in well, to go into the well the reasons such as overlong time, blanking plug fishing head is buried, cannot be pulled out, so, be badly in need of a kind of eccentric injection mandrel with sand setting passage and solve this difficult problem.
Description
Technical field
The present invention relates to oil field eccentric injection mandrel, particularly a kind of eccentric injection mandrel with sand setting passage.
Background technology
At present, when oil field at home is with eccentric injection mandrel seperated layer water injection, the blanking plug in injection well downhole flow regulator is needed to pull out, owing to containing sand setting and foreign material in well, to go into the well the reasons such as overlong time, blanking plug fishing head is buried, cannot be pulled out, so, be badly in need of a kind of eccentric injection mandrel with sand setting passage and solve this difficult problem.
Summary of the invention
The present invention is made up of top connection 1, centralizer body 2, adapter sleeve 3, main body 4, support 5, fairlead 6, lower contact 7.
Operating principle of the present invention is: sand setting passage main body 4 having up/down perforation, and this sand setting passage does not overlap with other hole and crosses.During oil pipe water filling, the sand setting in pipe and foreign material can drop in eccentric injection mandrel along with current, because this eccentric injection mandrel has sand setting passage, so blanking plug fishing head smoothly by main body 4, can not bury, cause the result that cannot pull out by sand setting and foreign material.
Beneficial effect of the present invention is: novel structure, and design is unique, when oil pipe water filling, sand setting in pipe and foreign material can not bury the fishing head of blanking plug, can be pulled out by blanking plug smoothly, improve operating efficiency, decrease the workload of pulling repeatedly, reduce operating cost.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention
Wherein: 1 top connection, 2 centralizer bodies, 3 adapter sleeves, 4 main bodys, 5 supports, 6 fairleads, 7 lower contacts.
Detailed description of the invention
Consult shown in Fig. 1, the present invention is made up of top connection 1, centralizer body 2, adapter sleeve 3, main body 4, support 5, fairlead 6, lower contact 7, it is characterized in that top connection 1 and adapter sleeve 3 are by being threaded, centralizer body 2 and main body 4 are for being welded to connect, support 5 with main body 4 for pin is connected, support 5 is with fairlead 6 for pin is connected, and adapter sleeve 3 and lower contact 7 are for being threaded.
