Abstract
A water injection well injection allocating device comprises an upper connector, an adjusting nut, a spring, a working barrel, a starting valve, a starting valve seat, a lower connector and a water allocating core. The inner threads of the lower portion of the upper connector are connected with the upper portion threads of the working barrel. The adjusting nut is connected with the outer threads of the lower portion of the upper connector. The working barrel is sleeved with the spring, and the spring is arranged below the adjusting nut. The starting valve is mounted outside the working barrel in a sleeved mode, and is located below the spring. The threads of the lower portion of the working barrel are connected with the threads of the middle portion of the lower connector. The starting valve seat is connected with the threads of the upper portion of the lower connector, and the starting valve is located on the valve opening of the upper end of the starting valve seat. An upper communication hole is formed in the working barrel, and the starting valve is located above the communicating hole. The water allocating core is mounted in the working barrel. The starting valve and the starting valve seat are independent parts. According to the water injection well injection allocating device, durable materials can be selected to carry out intensified treatment, scratch damage resistant performance can be greatly improved, service life can be prolonged, separated layer water injection can be carried out on the water injection well for a long term, oilfield development effects can be improved, and the water injection well injection allocating device has remarkable economic benefit.
Description
Technical field
The utility model is the device for the water injection well in oil fields injection allocation water yield, is a kind of water injection well distributor.
Background technology
Pressure difference packer is arranged, hollow distributor, ball-and-seat on the water injection string.The effect one of hollow distributor is to produce throttling, the 2nd, and to the water filling layer injection allocation water yield, make the water filling layer meet the requirements of water injection rate.Present hollow distributor is one-way flow, and injected water can only be from its inner outflow under certain pressure reduction, and the easy puncture damage of its throttle part causes its application life short, affects the benefit of separated-zone water infection oil field.
Summary of the invention
The purpose of this utility model is a kind of water injection well distributor of design, makes its long service life, makes the permanently effective seperated layer water injection of water injection well.
The purpose of this utility model is achieved in that and comprises top connection, regulate cap, spring, seating nipple, opening valve, open valve seat, lower contact, water distributing core, the top connection lower internal thread is threaded with seating nipple top, the transfer cap is connected with the top connection lower external thread, spring housing is contained in outside the seating nipple, and be under the adjusting cap, opening valve is sleeved on outside the seating nipple, and be under the spring, the seating nipple lower thread is threaded with the lower contact middle part, open valve seat and be threaded with lower contact top, opening valve is located on the upper end valve port of opening valve seat, and upper linked hole is arranged on the seating nipple, opening valve is on the linked hole, and water distributing core is installed in the seating nipple.
The beneficial effects of the utility model are: opening valve, unlatching valve seat are individual components, can select durable material to strengthen is in, can greatly improve anti-puncture damage performance, can increase the service life, make the permanently effective seperated layer water injection of water injection well energy, can improve Development Response of Oilfield, have significant economic benefit.
Description of drawings
Accompanying drawing is the assembling drawing of the utility model embodiment.
The specific embodiment
Below in conjunction with accompanying drawing the utility model embodiment is described.
As seen from the figure, embodiment of the present utility model comprises top connection 1, regulate cap 2, spring 3, seating nipple 4, opening valve 5, open valve seat 6, lower contact 8, water distributing core 9, top connection 1 lower internal thread is threaded with seating nipple 4 tops, transfer cap 2 is connected with top connection 1 lower external thread, spring 3 is sleeved on outside the seating nipple 4, and be under the adjusting cap 2, opening valve 5 is sleeved on outside the seating nipple 4, and be under the spring 3, opening valve 5 and seating nipple 4 fitted seal, the sealing of employing sealing ring, seating nipple 4 lower thread are threaded with lower contact 8 middle parts, open valve seat 6 and be threaded with lower contact 8 tops, opening valve 5 is located on the upper end valve port of opening valve seat 6, opening valve 5 and unlatching valve seat 6 fitted seal, guarantee sealing by crudy, linked hole 7 is arranged on the seating nipple 4, and opening valve 5 is on the linked hole 7, and water distributing core 9 is installed in the seating nipple 4.On the water distributing core 9 distributing tap is arranged, the water nozzle size determines by water filling layer injection allocation amount, and the distributing tap on the water distributing core 9 is aimed at linked hole 7, and water distributing core 9 is sealed by sealing ring with seating nipple 4 inwalls, and injected water can only be flowed out from the distributing tap on the water distributing core 9.Regulate the pressure that cap 2 can regulating spring 3 compacting opening valves 5, in order to adapt to the setting pressure of different packers.
Injected water flows out from the distributing tap on the water distributing core 9, and the linked hole 7 on seating nipple 4 arrives to be opened in the valve seat 6, and after water injection pressure acted on the pretightning force of thrust greater than spring 3 of opening valve 5 bottom surfaces, opening valve 5 was opened water filling.Supporting packer had been expanded Sealed casing pipe before opening valve 5 is opened with it, and injected water is opened opening valve 5 just can reality and seperated layer water injection.
