Description

Portable deciliter layering production controls device

Technical field

This utility model relates to technical field of oil extraction equipment, is specifically related to portable deciliter layering production and controls device.

Background technology

At present, for realizing changing layer exploitation, major part for above operation change packer and production mandrel be main oil production by layer, Pumping mixing oil recovery technique.Mainly have single tube to divide to adopt (in the producing well of exploitation multiple zone, if being separated into by oil reservoir with packer Dry section, uses card envelope or joins the mode of product to reduce interlayer interference) and multitube divide and adopt (several oil pipes under in a bite well, one Oil pipe one interval of exploitation, separates interval with packer) two class technology, owing to being limited by borehole diameter, oil field is many Using single-string selective zone production, its flow string working life is short, and layering looks for card water blockoff and layering production production operation complicated, not only Cause operating cost to rise, and produce recovering the oil and pump detection and workover has increased the weight of oil layer pollution.Single-string selective zone production is the most general Separate all over using point to adopt, point adopt and to mix out technique, existing technique at multilamellar, subdivision of reservoir, to change workload in layer abandoned wells big, put into Cost is high.

Summary of the invention

Original stratified stoichiometric device is improved by this utility model, is connected under oil well pump by device, can realize 2 oil reservoirs Independent separate zone production and two-layer exploitation, rely on the ground production fluid metering device can be to the production fluid side of carrying out when layering and combination producing Just measure.There is the aboveground of merit figure gauging, not only can realize deciliter layer oil recovery easily but also monolayer individually can be counted Amount, has unique advantage at low fluid supply capacity Jing Jianxiecaiyoujing and the well requiring monolayer to measure.Technology of the present utility model Scheme is: top connection connects lower contact by pump barrel, packer, and pump rod connects driving control device for reversing, and action joint passes through Check-valves, upper flow passage switch, lower step flow channel switch and slip transfer trajectory connect.

The beneficial effects of the utility model: practicality reasonable in design, change layer simple and convenient, can repeat to change layer with multilamellar, reduce Operations number, it is achieved that point adopt/close the accurate metering adopted, improves multiple-zone well layering card envelope effect, extends oil well and exempt from Repair the phase, can be used for straight well, inclined shaft and middle-deep well.

Detailed description of the invention

As shown in Figure 1 to Figure 2, portable deciliter layering production control device, mainly by top connection 1, pump barrel 2, pump rod 3, Drive control device for reversing 4, action joint 5, check-valves 6, upper flow passage switch 7, packer 8, lower step flow channel switch 9, slide Transfer trajectory 10 and lower contact 11 are constituted；Top connection 1 connects lower contact 11 by pump barrel 2, packer 8, and pump rod 3 connects driving and changes To controlling device 4, action joint 5 is by check-valves 6, upper flow passage switch 7, lower step flow channel switch 9 and slip transfer trajectory 10 Connect.

This utility model technological process: by tubing string down to oil reservoir position, packing is between two-layer, by the oil pumping of well head Bar controls pump rod 3 and drives driving control device for reversing 4 downward actuation, touch motion joint 5, makes interior tubing string move downwards, slides and turn Switching tracks and 10 change orbital position, transfer trajectory is as it is shown on figure 3, change the relative position of inside and outside tubing string, it is achieved upper flow passage is opened Pass 7 and the switch of lower step flow channel switch 9, thus realize independent separate zone production and the two-layer exploitation of 2 oil reservoirs.
