Abstract
The utility model provides a gas injection valve and relates to a valve device used in oil and gas field exploitation. The gas injection valve comprises a valve base and a valve rod arranged on the valve base. The other end of the valve rod is sleeved with a lower connector. The gas injection valve is characterized in that a copper sleeve is further arranged between the valve rod and the lower connector. Maximum deformation of the valve base is 0.00117mm, and maximum stress is 17.594MPa and appears in a valve base inner ring. The maximum deformation of the valve rod is 0.003556mm, and the maximum stress is 12.5284MPa. Requirements of gas injection development process are met, wear intensity of the valve rod is small, and service life can be effectively prolonged.
Description
Technical field
The utility model relates to a kind of a kind of valving that uses when exploitation of oil-gas field.
Background technology
The oil gas field major part that China has developed enters the middle and later periods, obtained remarkable effect although take the series of measures such as water filling, but reflect the series of problems such as water injection pressure is high, cost is high, permeability is low, production capacity is low in recent years in the water injection in low-permeability oilfield exploitation, have quite a few crude oil at underground mining not out, it is particularly important that the exploitation of remaining oil and complex reservoir just seems.In order to improve oil recovery factor, the oil production technology technology such as gas injection are more and more used.Because having easily, gas flows, reduces the effect of viscosity, volume expansion, reduction interfacial tension, oil reservoir kind, the degree of depth and scope that gas injection is suitable for are comparatively extensive, and be not subjected to the impact of formation temperature and salinity, therefore have a clear superiority in development of low-permeability oil reservoir.And the design of gas injection valve is just most important in gas injection development technique.
Summary of the invention
The utility model aims to provide a kind of not easy to wear, the gas injection valve of long service life.
Gas injection valve described in the utility model comprises valve seat and the valve rod that is arranged on valve seat, has been socketed lower contact on the valve rod other end, it is characterized in that also being provided with between valve rod and lower contact copper sheathing.
Preferably, on the lower end of valve rod and copper sheathing contact position, cover has spring.
Perhaps preferably, valve rod and valve seat contact position cover has spring.
The maximum distortion of the utility model valve seat is 0.00117mm, and maximum stress is 17.594MPa, appears at ring in valve seat.The maximum distortion of valve rod is 0.003556mm, and maximum stress is 12.5284MPa.Can satisfy the needs of gas injection development technique.And the wear intensity of its valve rod is little, can effectively increase the service life.
Description of drawings
Fig. 1 is the cut-away view of embodiment one.
The specific embodiment
Embodiment one.
Gas injection valve described in the utility model comprises valve seat 1, valve rod 2, lower contact 5 and copper sheathing 4.Valve rod 2 is arranged on valve seat 1, and copper sheathing 4 and lower contact 5 inner hollow have been socketed copper sheathing 4 on valve rod 2 other ends, and then valve rod 2 these ends are positioned at the inner hollow place of lower contact 5 together with copper sheathing 4.
In addition, on the lower end of valve rod 2 and copper sheathing 4 contact positions, cover has spring 3.Valve rod 2 also overlaps with valve seat 1 contact position spring 3.
Because valve rod 2 contacts continually with lower contact 5 under the gas effect, so easily wear and tear between valve rod 2 and lower contact 5 during use, affect service behaviour and the application life of gas injection valve.So the utility model is provided with a copper sheathing 4 between lower contact 5 and valve rod 2, can play good cushioning and protection to valve rod 2 and lower contact 5.
Claims (3)
1. gas injection valve comprises valve seat (1) and is arranged on valve rod (2) on valve seat (1), has been socketed lower contact (5) on valve rod (2) other end, it is characterized in that also being provided with copper sheathing (4) between valve rod (2) and lower contact (5).
2. gas injection valve as claimed in claim 1 is characterized in that on the lower end of valve rod (2) and copper sheathing (4) contact position, cover has spring (3).
