Abstract
The utility model provides a single deck tape -recorder tile bridging plug based on metal catch, includes the center tube and fixes throw -out collar, metal catch, pushing cylinder, metal sleeve, cone, single deck tape -recorder tile and the italic on the center tube from top to bottom in proper order. The metal catch be the cylindrical cavity solid of revolution of cover on the bridging plug center tube. The utility model discloses the alloy steel material that the metal catch was selected is not only all very strong in temperature toleration, crushing resistance, saved the structure of a slips moreover, has reduced the slip insert and has sat opposite and seal the damage of a section of thick bamboo, has shortened the whole length of bridging plug, has saved material and cost to the control of product quality application is in batch production better.
Description
Technical field
The utility model relates to a kind of oil field bridging plug, especially a kind of single deck tape-recorder based on metal lock ring watt bridging plug, belongs to bridge plug technology field under oil well.
Background technology
Along with increase day by day and the exploitation difficulty of consumption of petroleum, oil exploitation trend starts to be changed to horizontal well by Vertical Well, the pressure of underground increases along with the increase of mining depth simultaneously, cause common double slips bridging plug larger to the damage setting an inwall, so the single deck tape-recorder of a metal lock ring watt bridging plug structure is arisen at the historic moment.
Utility model content
For above-mentioned the deficiencies in the prior art, the utility model provides a kind of lock ring structure adopting alloy steel material, decreases slip insert to setting the damage of cylinder, the entire length shortening bridging plug, watt bridging plug of the single deck tape-recorder based on metal lock ring that saves material and cost, slow down the corrosion and damage speed of bridging plug.
For achieving the above object, the technical solution adopted in the utility model is: a kind of single deck tape-recorder based on metal lock ring watt bridging plug, comprises central tube and is fixed on throw-out collar on central tube, metal lock ring, pushing cylinder, metal sleeve, cone, single deck tape-recorder watt and italic from top to bottom successively.Described metal lock ring is the cylindrical, hollow revolving body be enclosed within bridging plug central tube.
Preferably, described metal lock ring internal and external parts is not made up of triangular sawtooth and angular thread.
Preferably, described triangular sawtooth is uniformly distributed horizontal by 15 ° of linea angulatas.
Preferably, the triangular sawtooth of described metal lock ring inside just coordinates with the rake tooth on central tube is that one-way movement one circle is stuck on central tube.
Preferably, described angular thread is outside at metal lock ring horizontal by 38 ° of angle screw arrangement.
Preferably, the angular thread of described metal lock ring and the threaded engagement be enclosed within the outside pushing cylinder of metal lock ring.
Preferably, described metal lock ring has the open slot of a place 5mm.
Alloy steel material selected by the utility model metal lock ring is not only all very strong in temperature tolerance, crushing resistance, and eliminate the structure of a slips, decrease slip insert to the damage setting cylinder, shorten the entire length of bridging plug, save material and cost, and control product quality is used in batch production better.

Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, to the technical scheme in the utility model embodiment carry out clear, intactly describe, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Embodiment
As shown in Figure 1-Figure 3: a kind of single deck tape-recorder based on metal lock ring watt bridging plug, comprise central tube 1 and be fixed on throw-out collar 2 on central tube 1, metal lock ring 3, pushing cylinder 4, metal sleeve 5, cone 6, single deck tape-recorder watts 7 and italic 8 from top to bottom successively.Described metal lock ring 3 is the cylindrical, hollow revolving bodies be enclosed within bridging plug central tube 1.Described metal lock ring 3 inside and outside is made up of triangular sawtooth 9 and angular thread 10 respectively.Described triangular sawtooth 9 is uniformly distributed horizontal by 15 ° of linea angulatas.It is that one-way movement one circle is stuck on central tube 1 that the triangular sawtooth 9 of described metal lock ring 3 inside just coordinates with the rake tooth on central tube 1.Described angular thread 10 is outside at metal lock ring 3 horizontal by 38 ° of angle screw arrangement.Angular thread 10 and the threaded engagement be enclosed within the outside pushing cylinder 4 of metal lock ring 3 of described metal lock ring 3, then metal lock ring 3 acts on metal sleeve 5 together with pushing cylinder 4.Described metal lock ring 3 has the open slot 11 of a place 5mm.Open slot 11 can ensure that lock ring has good elasticity, and metal lock ring 3 is bounced back along with profile of tooth is enclosed within central tube 1 step by step by opening.
Operating principle:
First along with profile of tooth to be enclosed within central tube then to compress a little step by step, metal lock ring ensures that pushing cylinder is spun on lock ring outside by threaded engagement by opening retraction, and have certain interval therebetween, last lock ring and pushing cylinder can only axial one-way movements.
When throw-out collar is subject to end thrust, lock ring one-way movement together with pushing cylinder promotes metal sleeve, and then cone is clamp-oned single deck tape-recorder watt until slip insert contacts with outer sleeve to set and enable bridging plug axial restraint firmly.
