Description
Technical field
The utility model relates to a kind of hollow water filling device, belongs to the hollow water distribution technical field of using in hyperbaric environment under oil well.
Background technology
Oilfield exploitation usually adopted to the mode of stratum water filling or polymer flooding and guarantees crude output to the later stage.Mode to the stratum water filling mainly contains two kinds at present, and a kind of is hollow water flooding regime, and another kind is the eccentric water injection mode.Its hollow water flooding regime mainly adopts the exploratory dropping-fishing test of fixed water nozzle, re-starts test after each water yield adjustment must be pulled whole water nozzles out transposing, reaches the purpose of the qualified injection allocation of layering, and the dropping-fishing test workload is large, surveys and transfers one-time success rate low.
Summary of the invention
The purpose of this utility model is, a kind of hollow water filling device is provided.Make fixed water nozzle into adjustable water nozzle, can realize completing in the down-hole adjusting of water injection rate, dropping-fishing test, alleviate the dropping-fishing test workload repeatedly, guarantees to survey and transfer once success, to overcome the deficiencies in the prior art.
The technical solution of the utility model:
A kind of hollow water filling device of the present utility model comprises upper body, and upper body is provided with weep hole, is provided with adjustable spool in the endoporus of upper body, and adjustable spool is connected by trapezoidal thread with the endoporus of upper body.The endoporus of adjustable spool is splined hole
In aforementioned means, described adjustable spool be shaped as tubulose, the endoporus of adjustable spool is splined hole.
In aforementioned means, described adjustable spool upper end is provided with upper spring, and adjustable spool lower end is provided with lower spring.
In aforementioned means, described upper body bottom is threaded with lower body.
In aforementioned means, the cylindrical of described upper body and lower body is provided with seal groove, is provided with sealing ring in seal groove.
Compared with prior art, the utility model has changed the aperture of weep hole to realize the adjusting of injection flow by adjustable spool moving axially in the upper body endoporus.Dropping-fishing test, alleviate the dropping-fishing test workload repeatedly, guarantees to survey once success of accent.The utility model in use can compatible first wife's water heater structure, and drive motors the stall phenomenon can not occur, and the sealing ring that is located on upper body and lower body adopts T-shaped sealing ring, is embedded in and can prevents in T-shaped groove that sealing ring from coming off in the down-hole.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Being labeled as in accompanying drawing: body, 7-weep hole, 8-splined hole under 1-sealing ring, 2-upper body, 3-upper spring, the adjustable spool of 4-, 5-lower spring, 6-.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing, but not as to any restriction of the present utility model.
The utility model is constructed according to following a kind of hollow water-filling method, as shown in Figure 1, the method is in the endoporus at weep hole 7 places of upper body 2, adjustable spool 4 to be set, by adjustable spool 4 moving axially in upper body 2 endoporus, change the aperture of weep hole 7, realize the adjusting of injection flow.Described adjustable spool 4 moving axially in upper body 2 endoporus is to realize by adjustable spool 4 and the trapezoidal thread in upper body 2 endoporus, when adjustable spool 4 rotated under the measurement and adjustment instrument device drives, adjustable spool 4 was realized moving axially in upper body 2 endoporus under trapezoidal thread drives.The rotation under the measurement and adjustment instrument device drives of described adjustable spool 4 is that the endoporus with adjustable spool 4 is processed into splined hole 8; Be connected with the measurement and adjustment instrument device by splined hole 8.Described adjustable spool 4 two ends are respectively equipped with upper spring 3 and lower spring 5, when trapezoidal thread is threaded off in rotary course, by upper spring 3 and lower spring 5 with adjustable spool 4 tops the trapezoidal thread in upper body 2 endoporus; Adjustable spool 4 can only be skidded on the trapezoidal thread of upper body 2, can prevent the motor generation stall of measurement and adjustment instrument device; Can in time the trapezoidal thread on adjustable spool 4 and the trapezoidal thread on upper body 2 in time be meshed in the time of simultaneously can guaranteeing to counter-rotate adjustable spool 4.Described upper body 2 bottoms are connected with lower body 6 by screw thread; The upper body 2 of can first upper spring 3, adjustable spool 4 and lower spring 5 being packed into successively from upper body 2 bottoms during installation, and then lower body 6 is connected with upper body 2.
The of the present utility model a kind of hollow water filling device device that builds according to said method is, this device comprises upper body 2, upper body 2 is provided with weep hole 7, is provided with adjustable spool 4 in the endoporus of upper body 2, and adjustable spool 4 is connected by trapezoidal thread with the endoporus of upper body 2.Described adjustable spool 4 be shaped as tubulose, the endoporus of adjustable spool 4 is splined hole 8.Described adjustable spool 4 upper ends are provided with upper spring 3, and adjustable spool 4 lower ends are provided with lower spring 5.Described upper body 2 bottoms are threaded with lower body 6.The cylindrical of described upper body 2 and lower body 6 is provided with seal groove, is provided with sealing ring 1 in seal groove.
The course of work of the present utility model and principle
As shown in Figure 1, the utility model is at weep hole 7 places of upper body 2, adjustable spool 4 to be set, and adjustable spool 4 is connected by trapezoidal thread with the endoporus of upper body 2, and the endoporus of upper body 2 is stepped hole.The endoporus of adjustable spool 4 is splined hole 8, is connected the adjusting that realizes adjustable spool 4 with the measurement and adjustment instrument device by splined hole 8.The measurement and adjustment instrument device drives adjustable spool 4 rotations, and adjustable spool 4 moves axially along upper body 2 aperture that changes weep hole 7 in rotary course, realize Flow-rate adjustment.Thread off in rotary course in order to prevent trapezoidal thread, be respectively equipped with upper spring 3 and lower spring 5 at adjustable spool 4 two ends, under the effect of upper spring 3 and lower spring 5, if when trapezoidal thread is threaded off in rotary course, adjustable spool 4 can only skid on the trapezoidal thread of upper body 2, can prevent the motor generation stall of measurement and adjustment instrument device.At this moment, as long as oppositely regulate adjustable spool 4, can guarantee in time that again trapezoidal thread on adjustable spool 4 and the trapezoidal thread on upper body 2 in time mesh.Upper body 2 lower ends are threaded with lower body 6.The cylindrical of upper body 2 and lower body 6 is provided with seal groove, and seal groove is T-shaped groove, is provided with sealing ring 1 in T-shaped groove, and sealing ring also adopts T-shaped sealing ring, can prevent that sealing ring 1 from coming off in the down-hole.
