Abstract
The utility model discloses an abrasion-proof reinforced sealing packing for oil exploitation. The sealing packing comprises a packing core, wherein a first abrasion-proof layer is wrapped on the outer surface of the packing core; a second abrasion-proof layer is wrapped on the outer surface of the first abrasion-proof layer; a reinforced ring is embedded between the first and the second abrasion-proof layers; and the first and the second abrasion-proof layers and the reinforced ring are vulcanized integrally. According to the utility model, the first and the second abrasion-proof layers are arranged at the outer part of the packing core, and lubricating oil is adhered to the packing core, so that the friction coefficient between the packing core and a polish rod is reduced, a better abrasion-proof effect is achieved, and the leakage of a wellhead is avoided. In addition, the reinforced ring prolongs the service life of the packing and reduces the number of times for replacing the packing at the wellhead. Therefore, the production cost is lowered, the yield of products is increased, and the environmental pollution is avoided.
Description
Technical field
The utility model relates to a kind of technical field of petroleum extraction, relates in particular to the wear-resisting enhanced leaktightness packing of a kind of oil exploitation.
Background technology
At present, rod pumping system is the main force of oil well production in the oil field, and wellhead polish rod sealer is absolutely necessary in the beam hanger oil pumping system, and wherein the structure of packing, performance are one of key factors of decision sealing effectiveness quality.Because recover the oil to get into the middle and later periods, the high oil content of extraction liquid moisture content is low, extraction liquid to the lubricant effect of polished rod worse and worse, the frictional resistance of the product of polished rod and packing is increasing; Existing packing material is single, and is not wear-resisting, and application life is very short, needs the frequent change packing; Frequent shutdown is changed packing on the one hand, has both increased cost of production, reduces production efficiency; Influence oil well output, bring certain hidden danger to safety work again, be prone to cause well head to reveal on the other hand environment is caused pollution to a certain degree.
Summary of the invention
To the problem that above-mentioned prior art exists, the utility model provides a kind of oil exploitation wear-resisting enhanced leaktightness packing.
To achieve these goals; The technical scheme that the utility model adopts is: the wear-resisting enhanced leaktightness packing of a kind of oil exploitation; Comprise the packing core, the external surface of packing core is coated with first wearing layer, and the external surface of first wearing layer is coated with second wearing layer; Be embedded with reinforcing ring between first wearing layer and second wearing layer, first wearing layer, second wearing layer and reinforcing ring sulfuration are one.
As preferably, first wearing layer is a nylon yarn layer.
As preferably, second wearing layer is the nylon layer of cloth.
Compared with prior art, the advantage of the utility model is: there are first wearing layer and second wearing layer in the outside of packing core, and is stained with profit oil; Reduced and polished rod between friction factor, make more wear-resistingly, avoided the well head leakage; Reinforcing ring has prolonged the application life of packing, has reduced the number of times that the oil well mouth changes packing, has reduced cost of production; Increase output, avoided environment pollution.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Among the figure: 1, packing core; 21, first wearing layer; 22, second wearing layer; 3, reinforcing ring.
The specific embodiment
To combine accompanying drawing that the utility model is described further below.
A kind of embodiment as the utility model; Consult Fig. 1; The utility model comprises packing core 1, and the external surface that the external surface of packing core 1 is coated with first wearing layer, 21, the first wearing layers 21 is coated with second wearing layer 22; Be embedded with reinforcing ring 3, the first wearing layers 21, second wearing layer 22 and reinforcing ring 3 sulfurations between first wearing layer 21 and second wearing layer 22 and be one.First wearing layer 21 is a nylon yarn layer.Second wearing layer 22 is the nylon layer of cloth.
There are first wearing layer 21 and second wearing layer 22 in the outside of packing core 1, and is stained with profit oil, reduced and polished rod between friction factor; Feasible more wear-resisting, avoided the well head leakage, reinforcing ring 3 has prolonged the application life of packing; Reduced the number of times that the oil well mouth changes packing; Reduce cost of production, increased output, avoided environment pollution.
Although having combined current taking as is that a most practical and preferred embodiment has been described the utility model; But be to be understood that; The utility model is not limited to the disclosed embodiments, and is intended to contain spirit and interior multiple modification and the equivalent arrangements of scope that is included in accompanying claims on the contrary.
