Abstract
The utility model relates to a novel pressure-reducing device for an oil thermal recovery well opening. The technical scheme is that the novel pressure-reducing device comprises an inlet stop valve, a primary pressure-reducing device, a secondary pressure-reducing device, a safety valve, an outlet stop valve, a drain valve and an outlet non-return valve, wherein the inlet stop valve, the primary pressure-reducing device, the secondary pressure-reducing device, the safety valve, the outlet stop valve, the drain valve and the outlet non-return valve are connected sequentially through pipes. The whole novel pressure-reducing device is installed on a pressure-reducing prying block. The primary pressure-reducing device is formed by connecting a primary pressure-reducing valve and a primary pressure-reducing pressure gauge; and the secondary pressure-reducing device is formed by connecting a secondary pressure-reducing valve and a secondary pressure-reducing pressure gauge. The drain valve is installed below the pipes. The novel pressure-reducing device has the advantages that stable pressure can be transmitted to the well opening effectively, the pressure can be adjusted according to different pressure requirements, and oil production efficiency is improved; reasonable process arrangement is favorable for protection of the pressure-reducing valves high in prices, the problem that back flowing of a gas injection boiler caused by sudden pressure changes of the well opening occurs so that service life of the boiler is shortened is solved simultaneously; and steam tracing can be performed on a thick oil conveying pipe, and thick oil conveying efficiency is effectively improved.
Description
Technical field
The utility model relates to a kind of petroleum thermal recovery wellhead equipment, particularly a kind of Novel pressure-reducing device.
Background technology
Heavy oil development is global hang-up, in energy source in China today in short supply, one of energy that the viscous crude resource is Chinese very important beyond doubt, viscous crude, as its name suggests, it is a kind of relatively oil of thickness, viscosity is high, and density is large, and viscous crude and the thin oil viscous crude that shows as intuitively is difficult to flow, but viscous crude is very responsive for temperature, after the high temperature and high pressure steam of 250 ℃-380 ℃ of injections in oil reservoir, the fluid and the skeleton that are in contact with it in oil reservoir are heated, and the viscosity of viscous crude has decline, reduced flow resistance, made oil well production increasing.In real work, the high-temperature steam that is produced by thermal recovery boiler only directly injects well head by simple step-down, due to the flow process disunity, causes the reducing valve damage greatlyr, has affected simultaneously application life of gas injection boiler.And different oil wells requires to differ for pressure, uses single reducing valve can not guarantee the stable of pressure.And because pressure is higher, lowers the temperature in conveyance conduit for viscous crude and can not accompany heat.
Summary of the invention
The purpose of this utility model is exactly in view of the foregoing defects the prior art has, a kind of Novel pressure-reducing device is provided, can effectively improve stability and the compliance of steam pressure, can be feed-line companion heat simultaneously, improve efficient and the transfer efficiency of heavy crude heat extraction.
Its technical scheme is: comprise that inlet shutoff valve, decompressor, secondary decompressor, safety valve, outlet shutoff valve, discharging valve, an outlet non-return valve connect to form by pipeline successively, integral installation is on the decompression unit piece, a described decompressor comprises reducing valve, once the pressure meter that reduces pressure connects to form, described secondary decompressor comprises that secondary reducing valve, secondary decompression pressure meter connect to form, and described discharging valve is installed in the below of pipeline.
Above-mentioned safety valve is connected to form by 1.04 times of safety valves, 1.06 times of safety valves.
The beneficial effects of the utility model are: 1, this decompressor can effectively be carried steady pressure for well head, requires to regulate according to different pressures, improves oil recovery efficiency; 2, rational flow arrangement is conducive to the higher reducing valve of price is protected, and prevents from simultaneously that the unexpected pressure of well head from changing the gas injection boiler is produced to pour in down a chimney, and reduces the application life of boiler; 3, can carry out steam tracing to the transport of thick oil pipeline, effectively extra-high-speed heavy oil transportation efficient.
Description of drawings
Accompanying drawing 1 is structural representation of the present utility model;
In upper figure: inlet shutoff valve 1, reducing valve 2, once reduce pressure pressure meter 3, secondary reducing valve 4, secondary decompression pressure meter 5,1.04 times of safety valves 6,1.06 times of safety valves 7, outlet shutoff valve 8, discharging valve 9, outlet non-return valve 10, decompression unit piece 11.
The specific embodiment
By reference to the accompanying drawings 1, the utility model will be further described:
The utility model comprises that inlet shutoff valve 1, decompressor, secondary decompressor, safety valve, outlet shutoff valve 8, discharging valve 9, an outlet non-return valve 10 connect to form by pipeline successively, integral installation is on decompression unit piece 11, a described decompressor comprises reducing valve 2, once the pressure meter 3 that reduces pressure connects to form, described secondary decompressor comprises that secondary reducing valve 4, secondary decompression pressure meter 5 connect to form, and described discharging valve 9 is installed in the below of pipeline; Above-mentioned safety valve is connected to form by 1.04 times of safety valves 6,1.06 times of safety valves 7.
Operating principle of the present utility model is as follows:
Inlet shutoff valve 1 carries out step-down for the first time by a reducing valve 2; show pressure value on the pressure meter 3 that once reduces pressure; carry out step-down for the second time through secondary reducing valve 4 again; show pressure value on secondary decompression pressure meter 5; in the pressure allowable fluctuation range under 1.04 times of safety valves 6 and 1.06 times of safety valves 7 protections through outlet shutoff valve 8 with outlet non-return valve 10 is delivered to well head or conveyance conduit heats, because the water that condensation and step-down resistance produce can be discharged by discharging valve 9.
The utility model can improve stability and the compliance of steam pressure effectively, can be feed-line companion heat simultaneously, has improved efficient and the transfer efficiency of heavy crude heat extraction.
Through the inside experiment of Shengli Oil Field, Karamay Oil Fields in Xinjiang units concerned with use this device of proof reasonable in design, flow process is rigorous, security performance is high, improves a lot for thermal recovery and the well head heavy oil transportation of oil well, has reached customer requirement.
