Description
Technical field:
The utility model relates to the matching used liquid dispenser of a kind of oil field water distribution packer.
Background technology:
Existing concentric integrated injection well downhole flow regulator has the following disadvantages: when injection well downhole flow regulator and water distribution packer are used, water is chewed upper and lower seal and is used " O " shape or "T"-shaped sealing ring, if sealing ring interference hour, poor sealing performance, when if interference is big, injection well downhole flow regulator is difficult for arriving down the precalculated position, and seal is easily scratched in the process of going into the well simultaneously, influence sealing effectiveness, cause that efficiency of construction is low, cost is high; Existing injection well downhole flow regulator main body is an one, and seal is subject to other external force influence in the lower tubular column process, is unfavorable for salvaging and delivering injection well downhole flow regulator, is unfavorable for that more changing water chews, and influences the water distribution effect.
Summary of the invention:
The purpose of this utility model is to overcome the weak point of above-mentioned prior art, drags for the formula liquid dispenser and provide in a kind of concentric integrated negative shrink fitting.
The purpose of this utility model can reach by following measure: seal is a leather cup formula packing element, and its external diameter is less than water distribution packer seating nipple internal diameter; Main body is inside and outside slide mass, and the central tube bottom of interior slide mass is threaded with round nut; The top cylinder bottom of outer slide mass is threaded with joint top, be positioned at the interior step place of joint by the central tube upper step, and there is sealing ring to seal, tongue and groove and screw thread are all arranged at top and the bottom, the stop collar top of the bottom of joint, overcoat and long cover, emboss pit by leather cup formula packing element is connected as a single entity it, places outside the interior slide mass; Pressure ring is fixed on leather cup formula packing element on joint, overcoat, long cover and the stop collar by screw thread, and a conical surface is arranged under the stop collar.
The purpose of this utility model can also reach by following measure: a step is arranged at the central tube top of interior slide mass, and there is main through hole at the center, in go up, in the next kidney slot that is equipped with, central tube has the three seals circle outward; On the corresponding position of kidney slot of the overcoat of outer slide mass, long cover and central tube circular hole is arranged, and on circular hole 180 degree directions, have a counterbore, water is chewed seat and is placed in overcoat, the long circular hole that overlaps, and seal with sealing ring, water is chewed and is contained in water and chews in the seat and seal with sealing ring, annulus penetrates overcoat, long putting, and swivel nut places in the counterbore, and annulus is fixed on overcoat and long putting.The hole of three different-diameters is arranged on the annulus wall, and the center in three holes at grade; The swivel nut outer cylinder has seal groove, and endoporus is a screwed hole.
The utility model has following advantage compared to existing technology: seal of the present utility model is a leather cup formula packing element, the liquid dispenser external diameter is less than water distribution packer seating nipple internal diameter, in tubing string, remove convenience, seal good sealing effect, again because main body is inside and outside slide mass, when going into the well, liquid dispenser is stuck in top connection place with fishing head, it carries inside and outside slide mass simultaneously, packing element is not influenced by other external force, and is not yielding; Liquid dispenser is at deadweight and last enclosed cavity, middle enclosed cavity, the effect lower seal sealing performance of enclosed cavity can improve greatly down, thereby improves efficiency of construction, reduces cost.Central tube has two kidney slots, makes three packing elements also can keep the better seal effect under the different situation of axial displacement, and the hole of three different-diameters helps getting and changes water and chew and locate on the annulus wall, and the endoporus of swivel nut is that screwed hole helps getting with instrument and changes.
Description of drawings:
Accompanying drawing is the utility model structural representation.
The specific embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing:
As shown in the figure: the utility model seal is a leather cup formula packing element 7, and its external diameter is less than water distribution packer seating nipple internal diameter; Main body is inside and outside slide mass, and central tube 4 bottoms of interior slide mass and round nut 17 are for being threaded; Top cylinder 1 bottom of outer slide mass is threaded with joint 3 tops, be positioned at the interior step place of joint 3 by central tube 4 upper step 20, and there is sealing 2 to seal, tongue and groove and screw thread are all arranged at top and the bottom, stop collar 16 tops of the bottom of joint 3, overcoat 8, long cover 14, emboss pit by leather cup formula packing element 7 is connected as a single entity it, places outside the interior slide mass; Pressure ring 6 is fixed on leather cup formula packing element 7 on joint 3, overcoat 8, long cover 14 and the stop collar 16 by screw thread, and a conical surface 30 is arranged at stop collar 16 bottoms.
One step 20 is arranged at central tube 4 tops of interior slide mass, and main through hole 25 is arranged, in go up, in the next kidney slot 22,26 that is equipped with, central tube 4 is outer three seals circle 5 and leather cup formula packing element 7 to form to go up enclosed cavity 21, middle enclosed cavity 24, enclosed cavity 29 down.
On kidney slot 22, the 26 corresponding positions of the overcoat 8 of outer slide mass, long cover 14 and central tube 4 circular hole is arranged, and on circular hole 180 degree directions, have counterbore, water is chewed seat 13 and is placed overcoat 8, grows in the circular hole of cover 14, and with sealing ring 9 sealing, water is chewed 11 and is contained in that water is chewed in the seat 13 and with sealing rings 10 sealing, annulus 12 penetrates on overcoat 8, the long cover 14, and swivel nut 15 places in the counterbore, and annulus 12 is fixed on overcoat 8 and the long cover 14.Have on annulus 12 walls three different-diameters 23, three holes, hole the center at grade.
During on-the-spot the use, the utility model and the supporting use of water distribution packer, the conical surface 30 is positioned step place in the packer seating nipple, behind the packer setting, maybe need to change water and chewed 11 o'clock, all need to trip out liquid dispenser, because packing element 7 is a negative shrink fitting, the liquid dispenser maximum outside diameter is less than the internal diameter of water distribution packer seating nipple, thus remove conveniently, thus improved the construction success rate.
During water distribution, open sluice gate, interior slide mass is by gravity pressure and hydraulic pressure, because the effect of step 20 promotes the descending compression packing element 7 of outer slide mass, make packing element 7 enter the duty of sealing, liquid by through hole 19, main through hole 25, go up enclosed cavity 21, middle enclosed cavity 24, enclosed cavity 29 down, chew 11 from water water injected the stratum, make water injection well reach good flood effectiveness.
