Description
Technical field
This utility model relates to a kind of oil recovery blowout control equipment, particularly to one oil recovery blowout prevention check device。
Background technology
In oil extraction in oil field technology, sucker rod pumping is still main method, the driving device on ground drives oil well pump to pump in oil pipe pump barrel by sucker rod, thus crude oil is pumped into ground, rod collar is widely used part in the sucker rod pumping system of oil field, the connection between sucker rod is realized by it, rod string is when down-hole normal operation, oil pumper drives on rod string, lower reciprocating motion, due to hole deviation, crude oil resistance, the impact of the factors such as the frictional force of rod string and tube inner wall, sucker rod will constantly be stretched, compression, the alternate load that bending and additional torque etc. are complicated, thus occurring sucker rod to loosen with screw threads of coupler and thread off, sucker rod is made to fall in oil well, cause down-hole accident, oil well is forced to stop production, have a strong impact on the production efficiency in oil field, add the production cost in oil field。Polished rod of pumping well is the key position of pumping unit, and it has two effects, and one is bear down-hole load by polished rod eye and side's clamp；Two are and wellhead packing box fitted seal well head。Impact due to polished rod quality and various work factor, its in working order under disconnected de-phenomenon happen occasionally, especially aboveground faster in viscosity of crude height, load weight or jig frequency, the probability of light rod-broken is very high, breaking after taking off, if polished rod fracture falls into below wellhead packing box, packing box will lose sealing function, OIH air-water mixture will spray well head, bring many difficulties to crude oil production and site safety management work。
Summary of the invention
The purpose of this utility model is aiming at the drawbacks described above that prior art exists, it is provided that a kind of oil recovery uses blowout prevention check device, and this apparatus structure is simple, cost is low, decreases the generation of down-hole accident, improves oil field productivity effect。
Its technical scheme is: include valve body, non-return mechanism, lower contact, valve inner is provided with non-return mechanism, the bottom of described valve body connects lower contact, described non-return mechanism includes mandrel, trip bolt, slips, slips cone seat, shaped seals circle, steel ball, spring, spring base joint, taper back-up ring, the centre of mandrel is provided with steel ball, described steel ball passes through spring supporting, core the tip of the axis is provided with spring base joint, the outside of mandrel is sequentially provided with slips cone seat, shaped seals circle, slips cone seat top is provided with slips, the top of mandrel is by the fixing taper back-up ring of trip bolt, described spring base joint is provided with relief hole。
Above-mentioned spring is volute spring, improves the thrust to steel ball。
The beneficial effects of the utility model are: this apparatus structure is simple, cost is low; decrease the generation of down-hole accident; improve oil field productivity effect; thoroughly solve oil, problem that gas leaks; protect national wealth not suffer a loss, and make oil well production safer, it is possible to avoid the oil gas leaked water causing packing box place to cause without control; improve the safety that crude oil production is on-the-spot, reduce the potential safety hazard in oil extraction process；Non-return mechanism can effectively prevent blowout。
Accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present utility model；
Accompanying drawing 2 is the structural representation of non-return mechanism；
In upper figure: valve body 1, non-return mechanism 2, lower contact 3；Mandrel 2.1, trip bolt 2.2, slips 2.3, slips cone seat 2.4, shaped seals circle 2.5, steel ball 2.6, spring 2.7, spring base joint 2.8, taper back-up ring 2.9。
Detailed description of the invention
In conjunction with accompanying drawing 1-2, the utility model will be further described:
This utility model includes valve body 1, non-return mechanism 2, lower contact 3, valve body 1 is internal is provided with non-return mechanism 2, the bottom of described valve body 1 connects lower contact 3, described non-return mechanism 2 includes mandrel 2.1, trip bolt 2.2, slips 2.3, slips cone seat 2.4, shaped seals circle 2.5, steel ball 2.6, spring 2.7, spring base joint 2.8, taper back-up ring 2.9, the centre of mandrel 2.1 is provided with steel ball 2.6, described steel ball 2.6 is supported by spring 2.7, the end of mandrel 2.1 is provided with spring base joint 2.8, the outside of mandrel 2.1 is sequentially provided with slips cone seat 2.4, shaped seals circle 2.5, slips cone seat 2.4 top is provided with slips 2.3, taper back-up ring 2.9 is fixed by trip bolt 2.2 in the top of mandrel 2.1, described spring base joint 2.8 is provided with relief hole 2.10。
Wherein, spring 2.7 is volute spring, improves the thrust to steel ball。
Operation principle:
When oil-well blowing omen, dismantle kelly bar immediately, this device is put in drilling rod hydrophthalmia, turn on pump send down in place after just can reach blowout prevention purpose, this tool construction is simple, handiness, as long as the joint screw thread dismantling kelly bar just can put in the hydrophthalmia of drilling rod, the purpose of interior blowout prevention after in place, just can be reached。
The above, be only preferred embodiment of the present utility model, and this utility model is all revised possibly also with the technical scheme of above-mentioned elaboration or is revised as equivalent technical scheme by any those of ordinary skill in the art。Therefore, any simple modification carried out according to the technical solution of the utility model or substitute equivalents, belong to the greatest extent the scope that this utility model claims。
