Abstract
The invention discloses a sealed packing element for deep swabbing of an oil well and relates to a deep swabbing device for the oil well. The sealed packing element comprises a hollow cylindrical packing element; at least three V-shaped sealing rings are arranged on the external circumference of the packing element; and the external diameter of the V-shaped sealing ring is slightly more than that of the packing element. Due to the design of V-shaped multi-path sealing mode, the sealing property of the packing element is greatly improved and the service life is prolonged. The number of the sealing paths is determined according to the actual requirement.
Description
Technical field
The present invention relates to a kind of oil well depth pumping means, relate in particular to a kind of pumping cartridge structure.
Background technology
The oil well pumping means that extensively adopt in China oil field, be valve formula pumping means, its principle is, after pumping means sinks to liquid, when being subjected to the power of upwards lifting, act on the head of liquid on the packing element, make packing element radial dilatation and tube inner wall form sealing, reach the purpose of extracting liquid out, it utilizes umbrella shape packing element pressurized, and radial dilatation forms sealing together, in its use, the packing element quick abrasion, poor sealing performance, wastage is big, application life is short, be prone to coming off of monoblock or bulk rubber, need regularly to salvage, the workman needs the frequent packing element of changing.New pumping means has appearred for this reason, no valve steel frame packing element device, when this kind pumping means upwards promotes, utilize the steel frame packing element, the dynamic loading that when motion, forms, make steel frame packing element radial dilatation and tube inner wall form sealing, reach the purpose of extracting liquid out, this kind pumping means good seal performance, wastage is little, compares valve formula pumping means, very big advantage is arranged, but the steel frame packing element quality of domestic production at present can not get effective assurance, and the steel frame packing element of import costs an arm and a leg, and has limited its application to a certain extent.
Summary of the invention
The present invention is directed to above-mentioned defective, purpose is to provide the pumping packing element of a kind of moderate cost, good seal performance.
Technical scheme of the present invention is: the novel cylindrical packing element body that comprises hollow, and the external circumference of packing element is provided with three road V-shaped rings at least, and the external diameter of V-shaped ring is slightly larger than the external diameter of rubber body.
The present invention is designed to the multiple-sealed mode of V-arrangement, and the sealing performance of packing element is greatly improved, and has obtained prolongation application life, and sealing of the present invention road number can determine according to actual needs.
Description of drawings
Fig. 1 is a structural representation of the present invention
1 is that packing element body, 2 is V-shaped ring among the figure.
The specific embodiment
The present invention includes the cylindrical packing element body 1 of hollow, packing element body 1 excircle is to being provided with three road V-shaped rings at least, and the external diameter of V-shaped ring 2 is slightly larger than the external diameter of packing element body 1.
Technology of the present invention can be applicable on the steel frame packing element.
Claims (1)
1. a sealed packing element for deep swabbing of oil well is characterized in that, comprises the hollow circular cylinder packing element, and the external circumference of packing element is provided with three road V-shaped rings at least, and the external diameter of V-shaped ring is slightly larger than the external diameter of packing element body.
