Abstract
The utility model discloses an oil well dirt-proof choking apparatus, which comprises a salvaging rod, a press cover, a sealing section, a liquid inlet, a water faucet and a bottom plug. The utility model is characterized in that the liquid inlet is in a porous and net-shaped structure. The utility model changes an open type liquid inlet of an original choking apparatus into the porous and net-shaped liquid inlet, effectively prevents the problem that mud, sand and oil dirt choke the water faucet, ensures the smooth operation of water injection work, and simultaneously, enhances work load.
Description
The utility model relates to the plugging device that use down-hole, a kind of oil field, the antifouling blanking plug of particularly a kind of oil well.
At present, the employed various blanking plugs in each oil field, the whole nation are the open type inlet, promptly offer three slotted holes on the seal section, because its antifouling property is not good enough, therefore silt particle, greasy dirt are easy to block water nozzle in the injecting process, cause water filling work not carry out smoothly.Still find no at present and the same or analogous record of the utility model.
The purpose of this utility model just is to provide a kind of silt particle, greasy dirt of effectively preventing to block water nozzle, has the antifouling blanking plug of cancellated oil well.
Technical solution of the present utility model is very simple, is exactly on the basis of existing plug structure, changes the inlet of its slotted hole, open type into the holey inlet and gets final product.
The utility model is simple in structure, and is easy to process, with low cost, and result of use is good; Adopt the cancellated inlet of porous type, not only can not reduce the afflux amount, and can also prevent effectively that silt particle, greasy dirt from blocking water nozzle, improved the water filling workload, can guarantee carrying out smoothly of water filling work.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is that A-A among Fig. 1 is to sectional view;
Fig. 3 is the schematic diagram of the open type inlet of original stifled 665-2 type blanking plug.
Most preferred embodiment is as follows: structure of the present utility model is to improve a little on the basis of original stifled 665-2 type blanking plug and get, wherein 6 structures are blocked up all with original identical in fishing rod 1, gland 2, seal section 3, corundum porcelain water nozzle 5 and the end, they link together in turn, just change inlet 4 into the porous type net structure by the slotted hole open type, thereby effectively prevented silt particle, greasy dirt obstruction, guaranteed carrying out smoothly of water filling work water nozzle.
