Abstract
The utility model provides an oil pipe pumping device with a simple structure and multilevel random combination for oil field producing well pumping and discharging construction. The device consists of an upper tie-in 1, a centre rod 2, a glue cylinder 4 and a pipe plug, wherein, the glue cylinder 4 is arranged on the centre rod 2; the upper tie-in 1 is connected to the upper part of the centre rod; the taper pipe plug 7 is arranged on the lower part of the centre rod. The glue cylinder 4 adopted by the utility model is combined by a plurality of V-shaped glue cylinder elements by sulfuration, and such a structure is abrasion resistant and has good leak tightness. The inner part of the centre rod 2 has a pylome and the lower part is provided with a flow guide hole, which increases the flow channel and reduces the downstream resistance in the pumping and discharging process. In the process of upstream, the glue cylinder 4 slides downwards to seal the flow guide hole; meanwhile, the glue cylinder 4 puffs to push the fluid inside the oil pipe to flow upwards so as to realize the pumping and discharging functions inside the oil pipe.
Description
Affiliated technical field:
The invention belongs to the oil field downhole tool
Background technology:
In oil field development, the pumping fluid-discharge technology is the oil pipe pumping means to be lowered to carry out pumping in the oil pipe, and is simple, convenient, flexible because of the construction of pumping fluid-discharge technology, uses when being everlasting formation testing or discharge opeing.
The present pumping means that uses has the following disadvantages in application:
Wastage was bigger when 1, the pumping means packing element adopted the pumping of split-type structure, and pumping efficient is low; The wearing and tearing of expanding glue, the part of wearing and tearing can not be filled timely, and wastage progressively increases, and application life is short.
2, transfer and do not have flow-guiding channel in the process, lowering velocity is slow, easily is hampered.
Summary of the invention:
Big in order to solve existing pumping means wastage, lack and the big deficiency of descending resistance application life, and the utility model provides a kind of oil pipe pumping means, to overcome the above problems.
The technical scheme that its technical problem that solves the utility model adopts is: adopt plural serial stage pumping structure, improve the packing element hermetically-sealed construction, increase descending flow channels, improve up pumping sealing.The utility model is made up of top connection 1, center-pole 2, packing element 4, plug 7 four parts.In Fig. 1, top connection 1 upper end is a pin thread, and the lower end is a box, and box inside is hollow structure, circumferentially has pod apertures.What link to each other with the top connection bottom is multistage center-pole 2 (Fig. 1 is two-stage), and the center-pole bottom is a plug 7.Center-pole inside is through hole, the upper end is a pin thread, the lower end is a box, spacing type conical bench is arranged at the bottom, with moving of restriction, cartridge, the body of rod design on limited step top has pod apertures, can make the pod apertures of the fluid of packing element bottom by center-pole in the descending process, walk around large diameter packing element through the pod apertures of center-pole inner chamber and top connection, reduce descending resistance.The plug of center-pole bottom, but the inside flow channels of blocked center bar prevent in the pumping process, fluid leakage, its pyramidal structure has guide effect simultaneously.Packing element 4 is installed on the center-pole 2, and its packing element body is by the several layers of V-type packing element element that hardness is different, and alternate combinations forms, and topmost top packing element 3 is hexagonal packing element element by cross-sectional area; The packing element bottom is a V row metal packing element base 6, and several steel wires 5 of circumferential parallel distribution link to each other with base, constitute the metallic support skeleton jointly.Metallic support skeleton and each packing element element are as a whole by being sulfided into.
The utility model adopts plural serial stage pumping structure, can make the pod apertures of the fluid of packing element bottom by center-pole in the descending process, walks around large diameter packing element through the pod apertures of center-pole inner chamber and top connection, reduces descending resistance.V-type packing element elements combination structure can utilize top hydraulic pressure to magnify sealing, and the packing element sealing of still remaining valid of partly wearing and tearing in the pumping process prolongs packing element application life.
Description of drawings:
Fig. 1: the structure complete section figure of the utility model oil pipe pumping means.
1, top connection 2, center-pole 3, top packing element 4, packing element 5, steel wire 6, packing element base 7, plug
The specific embodiment:
The utility model is made up of top connection 1, center-pole 2, packing element 4, plug 7 four parts.In Fig. 1, top connection 1 upper end is a pin thread, and the lower end is a box, and box inside is hollow structure, circumferentially has pod apertures.What link to each other with the top connection bottom is multistage center-pole 2 (Fig. 1 is two-stage), and the center-pole bottom is a plug 7.Center-pole inside is through hole, the upper end is a pin thread, the lower end is a box, spacing type conical bench is arranged at the bottom, with moving of restriction, cartridge, the body of rod design on limited step top has pod apertures, can make the pod apertures of the fluid of packing element bottom by center-pole in the descending process, walk around large diameter packing element through the pod apertures of center-pole inner chamber and top connection, reduce descending resistance.The plug of center-pole bottom, but the inside flow channels of blocked center bar prevent in the pumping process, fluid leakage, its pyramidal structure has guide effect simultaneously.Packing element 4 is installed on the center-pole 2, and its packing element body is by the several layers of V-type packing element element that hardness is different, and alternate combinations forms, and topmost top packing element 3 is hexagonal packing element element by cross-sectional area; The packing element bottom is a V row metal packing element base 6, and several steel wires 5 of circumferential parallel distribution link to each other with base, constitute the metallic support skeleton jointly.Metallic support skeleton and each packing element element are as a whole by being sulfided into.
When using at the scene, the upper end of top connection 1 connects with the rope socket of pumping wire rope, by wire rope pumping means is arrived projected depth down, to carry pumping means on the certain speed, under the fluid column inertial pressure of top, the packing element compression-expansion, seal with tube inner wall, take upper flow to ground, repeatedly repetitive operation can reach the pumping effect.Well head will be installed supporting well control safety devices such as lubricator during use.
