Abstract
The utility model relates to an oil-gas well solid chemical agent dispenser using in oil-gas field for oil recovery and gas production projects, which comprises an end cover (1), an upper contact (2), an O ring (3), a charging case (4), a connecting pipe (5), a pressure meter (6) and an emptying valve (7) and is characterized in that the end cover (1) is connected with the upper contact (2), the connecting pipe (5) is arranged on a side face of the charging case (4) and the pressure meter (6) and the emptying valve (7) are positioned orderly on the connecting pipe (5). The utility model has the advantages that the structure is simple and portable free of moving elements, the operation is simple and reliable and the solid chemical agent dispensing can be resolved. The utility model is suitable for the oil-gas well for periodic foaming agent dispensing and the oil-gas well which cannot be injected with the liquid foaming agent.
Description
Technical field
The utility model relates to oil gas field oil recovery, gas production engineering, specifically, is a kind of oil gas field oil gas well Solid-state Chemistry agent dispenser.
Background technology
In oil gas field production development process, the shaft bottom hydrops of gas well, the post-job raffinate of oil well measure all need the discharge opeing technology in time to discharge pit shaft.At present, the discharge opeing technology that is applied to oil gas field has oil pumper discharge opeing, electric submersible pump discharge opeing, hydraulic piston pump discharge opeing, gaslift discharge opeing and chemical blowing agent discharge opeing technology such as (being the foaming water discharge technology), every kind of technology all has its compliance, and each oil field is according to self oil well feature selecting 1-2 item technology even the multinomial technology discharge opeing problem that rationally solves this oil field.The foaming water discharge technology mainly is adapted to the gas well discharge opeing, this technology is suitable frother to be added had shaft bottom hydrops gas well, under its dissolving and effect, will produce a large amount of foams, utilize foam to improve fluid-carrying capability, hydrops is given rise to ground continuously at air-flow.After hydrops was removed, the output of gas well generally will be recovered.This technology also has been applied to the draining of part oil well at present.
The method that frother adds the oil gas well has two kinds, and a kind of is to utilize ground flow to obtain equipment the liquid frother is injected the down-hole from the oil jacket annular space, and this method does not influence the production of oil gas well, and system self can realize dosing at regular time and quantity, is fit to sizable application.But,, also be not suitable for the oil gas well application that northern oil gas field used and be with the packer completion winter in addition therefore for the application inconvenience of small quantity of oil gas well because ground flow will be installed; Another kind is exactly to utilize special tool or equipment that the solid frother is rendered to the down-hole in oil pipe, and this method is that the former useful replenished, and is suitable for the oil gas well that the former should not adopt.
Summary of the invention
It is simply light that being of mother of the present utility model provides a kind of apparatus structure, movement-less part, operation is simple and reliable, can solve the input operation of solid frother, the oil gas field that is suitable for irregularly throwing in the oil gas well of frother and can't inject liquid frother oil gas well Solid-state Chemistry agent dispenser.
The utility model is achieved in that and comprises top end cover, top connection, O shape circle, cartridge, tube connector, pressure meter, atmospheric valve, top end cover is connected with top connection, tube connector is installed in the cartridge side, and pressure meter, atmospheric valve are installed on the tube connector successively.
Following technical scheme is adopted in the utility model sea:
Adopt taper pipe thread to connect between top connection and the cartridge; Adopt trapezoidal thread to connect between top end cover and the top connection, be provided with O shape circle between top end cover and the top connection.
Cartridge adopts taper pipe thread to be connected with tube connector.
The lower contact of cartridge is provided with the Taper Pipe male thread.
The beneficial effects of the utility model are: apparatus structure is simply light, movement-less part, and operation is simple and reliable, can solve the input operation of solid frother, is suitable for the oil gas well of irregularly throwing in the oil gas well of frother and can't injecting the liquid frother.
Description of drawings
Accompanying drawing is a structural representation of the present utility model
The specific embodiment
As shown in drawings, 1-top end cover 2-top connection 3-O shape circle 4-cartridge 5-tube connector 6-pressure meter 7-atmospheric valve
All adopt the thread connecting mode of different performance between top end cover of the present utility model, top connection 2, cartridge 4, tube connector 5, pressure meter 6 and the atmospheric valve 7, without any welding, be provided with O shape circle 3 between end cap 1 and the top connection 2, adopt taper pipe thread to connect between top connection 2 and the cartridge 4 to guarantee sealing; Adopt trapezoidal thread to connect between top end cover 1 and the top connection 2 and be convenient to quick loading and unloading, its sealing problem is solved by O shape circle 3; Tube connector 5 is installed in cartridge 4 sides, adopts taper pipe thread to protect and connects the card sealing; The lower contact of cartridge 4 is Taper Pipe male threads, paraffin valve connected mode (being generally Taper Pipe box thread or flange) is complementary on energy and the oil gas well production tree, if the interface that paraffin valve is reserved is a flange, a dress changing-over head then is installed in the lower contact of cartridge 4 again can be realized reliable connection.Close paraffin valve, open atmospheric valve 7, make that device is inside and outside to communicate with atmosphere, unload top end cover 1 this moment, can be safely the chemical agent of solid (as spherical, bar-shaped etc.) threading cartridge 4; Load onto top end cover 1, close atmospheric valve 7, open paraffin valve, device becomes a pressure system with oil well, and this moment, the chemical agent of solid fell into the shaft bottom in the effect of self gravitation.Repeat said process, can finish input operation the agent of oil well some Solid-state Chemistry.
During the utility model operate as normal, the production tree main valve is in open position, and the both sides flutter valve is in close stance.During installation or removal the utility model, the production tree paraffin valve is in close stance, and atmospheric valve 7 is in open position.Pressure meter 6 and atmospheric valve 7 are the universal product, get final product according to the pressure rating type selecting.
