Abstract
Disclosed is an annular rubber core with high elasticity, high pressure and abrasion resistance, which is applied to an oil annular blowout preventer. The utility model is characterized in that: a steel component is arranged at both ends of a rubber cylinder, and the steel component is vulcanized with the rubber cylinder at both ends. Two seal grooves are arranged on the outer wall of the steel component, the steel component and the vulcanized end face of the rubber cylinder have an inward recessed annular groove, and the end part of the rubber cylinder is vulcanized in the annular groove. A vulcanized rubber layer is disposed on the inner wall of the steel component. The inside diameter of the vulcanized rubber layer is the same with the inside diameter of the rubber cylinder. Two symmetrical bolt points are respectively arranged at the outer end parts of the steel component. The utility model has the effects that: the annular rubber core with high elasticity, high pressure and abrasion resistance is highly elastic and abrasion resistant and has large sealing area, short well closing time, evenly distributed compression stress, high pressure bearing, long service life, safe and convenient installation, time saving and strong on-site practicability. Rubber cores with various through diameters can be designed as required for meeting the requirements of annular blowout preventer cylinder shape rubber cores of various types.
Description
Technical field
The utility model relates to oil equipment technology field, and particularly annular preventer is the annular high-elastic high-pressure anti-wear glue core that uses on the annular preventer, core part in the annular preventer.During operation, by the effect of external hydraulic pressure, annular rubber core overcomes the annular space hydraulic pressure and is gathered, encircles pipe by the center of being forced to, and plays the effect of non-stop plugging annular space under the band kill-job, realizes the environmental protection operation.
Technical background
At present, the annular preventer glue core of Operating Pressure use is a tubular glue core.By using for many years, effect is unsatisfactory.
Changing the glue core loses time: time-consuming at least 2.5-3 hour of glue core of every replacing, and average every mouthful of well is changed 2.5 times, and construction operation a bite well is changed glue core waste engineering time 6-7.5 hour.
Loss hydraulic oil is many: on average change a glue core and lose 35 kilograms in hydraulic oil.
Existing in addition glue core costs an arm and a leg, and increases individual well construction accessory and takes.
By Field Research with check, find that all breakdown points all are rubber and steel component joints up and down.Analyze conclusion: steel component is long, and the sealing radius of curvature is little; By the colloid analysis, rubber abrasive-resistance is poor; Simultaneously, rubber and steel component joint pressure-bearing skewness, oil pipe body and tubing coupling and glue in-core wall rubber friction when removing oil pipe, scrape knock due to.
Technology contents
The purpose of this utility model is: the high-elastic high-pressure anti-wear glue of a kind of annular core is provided, changes its structure, can use in annular preventer, play the effect of non-stop plugging annular space; And it is big to have elastic force, and the closed-in time is short; The high sealing of pressure-bearing area ambassador is with effective; The strong long service life of abrasion resistance; The installation safe ready saves time, and exempts personal injury, reduces labor intensity.Improve the operation actual effect, reduce operating cost, help protecting environment.
The technical solution of the utility model is: annular high-elastic high-pressure anti-wear glue core comprises steel components and packing element.The external diameter of steel components and packing element is identical, and steel components and packing element have central through hole.It is characterized in that: steel components is at the two ends of packing element, and the packing element at steel components and two ends sulfides.The two seals groove is respectively arranged on the outer wall of steel components, and the effect of seal groove is to install and fix V-shaped seal ring.On the end face of steel components and packing element sulfuration the annular recess that caves inward is arranged, the end sulfuration of packing element is in annular recess.The vulcanized rubber layer is arranged on the inwall of steel components.The internal diameter of vulcanized rubber layer is identical with the internal diameter of packing element.The bolt hole that two symmetries are respectively arranged in the outer end of steel components.
When making packing element be subjected to external pressure, the easier deformation that curves inwardly has the twice cannelure on the outer wall of packing element.The cross section of twice cannelure is a circular arc.The radius of circular arc is between the 40-60 millimeter, and the width of circular arc is between the 30-50 millimeter.
The beneficial effect of high-elastic high-pressure anti-wear annular rubber core is: can be designed to multiple latus rectum glue core as required, can satisfy the demand of multiple model annular preventer cartridge type glue core, adapt to the requirement of down-hole, oil field well Operating Pressure development, realize the environmental protection operation.The installation safe ready saves time,
Steel component is short, and packing element sealing radius of curvature is big, and contact area is big, and sealing effect is good; Adopt import high-elastic wear-resistant elastomeric material, add additives such as high-abrasive material, abrasion resistance is good, and be five times of other glue core application life.Cannelure is adopted in rubber and steel component sulfuration lower end, junction surface, prevents that stress is concentrated, and it is even to reach pressure-bearing; The bolt hole of two symmetries is bored in steel component section lacing wire center, and set bolt is convenient to change the glue core, improves the production actual effect.
