Abstract

The utility model discloses a production allocation machine, and belongs to the field of layered exploitation. The production allocation machine aims to solve the technical problem of incapability of exploring various oil layers in a balanced manner due to the fact that differential pressures of production of different fluid producing layers are different from one another and liquid drainage of the low-yield fluid producing layers is suppressed by the high-yield fluid producing layers of oil wells. The technical scheme for solving the technical problem includes that internal threads at the lower end of an upper joint are connected with external threads at the upper end of a base pipe, a space between the upper joint and the base pipe and a space between the upper joint and a rotary drum are respectively sealed by rubber sealing rings, the inner-diameter side of the rotary drum is respectively connected with the outer-diameter side of the upper joint and the outer-diameter side of a main valve, four valve seats and valve balls are peripherally distributed in the main valve, water nozzles with different diameters are arranged at fluid inlets of the valve seats, the main valve is connected with the base pipe in a slidably sleeved manner, and a space between the main valve and the rotary drum, a space between the main valve and the base pipe and spaces among the main valve and the valve seats are sealed by rubber sealing rings. Screen cloth and a screen pipe are arranged in a lower joint, the screen cloth can be positioned under the limiting effect of the screen pipe, the outer side of the lower end of the base pipe is connected into the lower joint in a threaded manner, and a space between the base pipe and the lower joint is sealed by a rubber sealing ring.

Description

Production mandrel
Technical field
The utility model relates to separate zone production field, what be specifically related to is production mandrel.
Background technology
Due to the difference of geological conditions, the producing pressure differential difference of different fluid producing layers, the interlayer that pressure reduction is large can produce interference, makes high output of oilwell liquid layer suppress low fluid producing layer fluid, causes each oil reservoir balanced to exploit, and has reduced tar productivity.
Summary of the invention
In order to overcome the producing pressure differential difference of different fluid producing layers, the interlayer that pressure reduction is large can produce interference, make high output of oilwell liquid layer suppress low fluid producing layer fluid, cause the deficiency that each oil reservoir cannot balanced exploitation, the utility model provides one to can be used for several production ranges, solves interlayer interference, alleviate interlayer and the aspect contradiction of oil-water well, variant interval is joined to product, controlled the different producing pressure differential of each production range, in the hope of different output.
The technical scheme in the invention for solving the technical problem is: this production mandrel is by top connection, central tube, rotating cylinder, main valve body, lower contact, valve seat, screen casing, water nozzle, valve ball, screen cloth composition, the lower end internal thread of top connection is connected with the upper external screw thread of central tube, top connection and central tube, between rotating cylinder, sealed with O-ring seal respectively, rotating cylinder internal diameter is respectively at top connection external diameter, main valve body external diameter is connected, 4 valve seats and valve ball circumferentially distribute in main valve body, the water nozzle of different-diameter is housed at the liquid inflow entrance place of valve seat, main valve body is connected in the mode of sliding sleeve with central tube, main valve body respectively with rotating cylinder, central tube, between valve seat, all sealed with O-ring seal, screen cloth and screen casing are housed in lower contact, screen casing can limit the position of screen cloth, outside, central tube lower end is connected with thread connecting mode with lower contact inside, between central tube and lower contact, adopt O-ring seal to seal.
The beneficial effects of the utility model are that the utility model provides one to can be used for several production ranges, solves interlayer interference, alleviate interlayer and the aspect contradiction of oil-water well, variant interval is joined to product, controlled the different producing pressure differential of each production range, in the hope of different output.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
1 top connection in figure, 2 central tubes, 3 rotating cylinders, 4 main valve bodies, 5 lower contacts, 6 valve seats, 7 screen casings, 8 water nozzles, 9 valve balls, 10 screen clothes.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is further described: as shown in Figure 1, production mandrel is made up of top connection 1, central tube 2, rotating cylinder 3, main valve body 4, lower contact 5, valve seat 6, screen casing 7, water nozzle 8, valve ball 9, screen cloth 10.The lower end internal thread of top connection 1 is connected with the upper external screw thread of central tube 2, between top connection 1 and central tube 2, rotating cylinder 3, is sealed respectively with O-ring seal.Rotating cylinder 3 internal diameters are connected respectively at top connection 1 external diameter, main valve body 4 external diameters, main valve body 44 valve seats 6 of interior circumferential distribution and valve ball 9, the water nozzle 8 of different-diameter is housed at the liquid inflow entrance place of valve seat 6, main valve body 4 is connected in the mode of sliding sleeve with central tube 2, and main valve body 4 is all sealed with O-ring seal respectively and between rotating cylinder 3, central tube 2, valve seat 6.Screen cloth 10 and screen casing 7 are housed in lower contact 5, and screen casing 7 can limit the position of screen cloth 10, and central tube 2 outsides, lower end are connected with thread connecting mode with lower contact 5 inside, between central tube 2 and lower contact 5, adopt O-ring seal to seal.Well liquid, after the inlet opening in lower contact 5 is come in, result in blockage to prevent that the impurity such as sand from entering through the filtration of screen cloth 10 and screen casing 7, then passes through valve seat 6 through water nozzle 8 current limlitings, backs down valve ball 9 and enters in central tube 2, and the oil well pump of above passing through is discharged well head.Wherein water nozzle 8 adopts the finished product water nozzle that dispensing well is used, and choosing of water nozzle bore can be used with reference to dispensing well according to the pressure of this well and traffic requirement.Water nozzle can fill at most 4, while not needing many liquid-through holes, can be equipped with dead mouth to logical liquid measure requirement is little, thus variant interval is joined to product, has controlled the different producing pressure differential of each production range, in the hope of different output.
