Abstract
The utility model provides an eccentric sand setting formula gas defense device, by top connection 1, outer tube 2, inner tube 3, eccentric block 4, plug 5, lower clutch 6, guide cone plug 7 constitute, the utility model discloses owing to adopt top connection and outer tube, lower clutch, guide cone plug to connect gradually, in the top connection with inner tube, plug connection, it has eccentric block to distribute on the outer tube, has the guide hole on the outer tube, there is the sand through hole inner tube below, peculiar eccentric structure can prevent during gaseous entering pump by the efficient to twice use eccentric structure, thereby abundant with gas and liquid separation, make the gassiness volume of the liquid of entering pump effectively reduce, reach the purpose that improves the pump efficiency. The utility model has the advantages of simple structure and reasonable design, convenient to use, very suitable on-the-spot popularization and application.
Description
Technical field:
The utility model is a kind of downhole tool that a kind of oil field thin oil oil well uses, but particularly a kind of off-centre sand setting formula gas-proofing apparatus.
Background technology:
Present shaking out and contain the technology that the oil well of association natural gas uses in the oil field, have an obvious limitation: reason is because original gas anchor structural limitations, can only reach part and prevent that gas from entering the purpose in the pump, and can not be used for sand well, because when sand production deposits to when a certain amount of, the feed liquor duct of gas anchor inside will be blocked, thereby cause oil well inspection pump.
Technical scheme:
But the purpose of this utility model is to provide a kind of off-centre sand setting formula gas-proofing apparatus.Can prevent efficiently that gas from entering in the pump, but can connect several sand sediment pipes in off-centre sand setting formula gas-proofing apparatus bottom again, thereby avoid oil well to cause frequently examining the purpose of pump because of the gas anchor structural limitations.The distinctive eccentric structure that it adopts can prevent efficiently that gas from entering in the pump, and uses eccentric structure twice, thereby fully with gas and fluid separation applications, the feasible air content that enters the liquid of pump effectively reduces, and reaches the purpose that improves pump efficiency.
The purpose of this utility model is to realize like this, mainly form by top connection (1), outer tube (2), interior pipe (3), eccentric block (4), plug (5), lower contact (6), starting taper plug (7), top connection (1) is connected successively with outer tube (2), lower contact (6), starting taper plug (7), in top connection (1), be connected with interior pipe (3), plug (5), on outer tube (2), be distributed with eccentric block (4), outer tube has guide hole on (2), and there is sand hole interior pipe (3) below.
In pumping pipe string, but off-centre sand setting formula gas-proofing apparatus (but off-centre sand setting formula gas-proofing apparatus removes the part behind the starting taper plug) is installed under the oil well pump, but and then several oil pipes are installed below off-centre sand setting formula gas-proofing apparatus, but at last the starting taper plug in the off-centre sand setting formula gas-proofing apparatus is installed in tubing string bottom as sand sediment pipe.
The utility model is owing to adopt top connection to be connected successively with outer tube, lower contact, starting taper plug, in top connection, be connected with interior pipe, plug, on outer tube, be distributed with eccentric block, guide hole is arranged on the outer tube, and interior pipe below has sand hole, distinctive eccentric structure can prevent efficiently that gas from entering in the pump, and use eccentric structure twice, thereby fully with gas and fluid separation applications, the feasible air content that enters the liquid of pump effectively reduces, and reaches the purpose that improves pump efficiency.The utility model is simple in structure, reasonable in design, and is easy to use, is well suited for field popularization application.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
Below in conjunction with accompanying drawing the utility model is further specified.
Embodiment
As shown in the figure, the purpose of utility model is to realize like this, mainly form by top connection 1, outer tube 2, interior pipe 3, eccentric block 4, plug 5, lower contact 6, starting taper plug 7, top connection 1 is connected successively with outer tube 2, lower contact 6, starting taper plug 7, in top connection 1, be connected with interior pipe 3, plug 5, be distributed with two groups of eccentric blocks 4 on outer tube 2, on the outer tube 2 guide hole arranged, there is sand hole interior pipe 3 belows.
Claims (1)
- But 1, a kind of off-centre sand setting formula gas-proofing apparatus, mainly form by top connection (1), outer tube (2), interior pipe (3), eccentric block (4), plug (5), lower contact (6), starting taper plug (7), it is characterized in that: top connection (1) is connected successively with outer tube (2), lower contact (6), starting taper plug (7), in top connection (1), be connected with interior pipe (3), plug (5), on outer tube (2), be distributed with eccentric block (4), outer tube has guide hole on (2), and there is sand hole interior pipe (3) below.
