Abstract
The utility model relates to a rotary stabilizer with a shock absorption effect and belongs to the field of petroleum and gas drilling equipment. The rotary stabilizer mainly comprises a strengthening body, a spiral sealing element, a rubber sleeve and an anti-wear element, wherein the anti-wear element and the rubber sleeve are tightly fastened on the strengthening body, the strengthening body is connected with a rotating mandrel through a rolling bearing, a gap is arranged between the strengthening body and the rotating mandrel, the threaded sleeve is connected onto the strengthening body through screw threads, the spiral sealing element is fixedly connected onto the rotating mandrel through fastening screws, and the rolling bearing is sealed by the spiral sealing element and a felt sealing ring. The rotary stabilizer has the advantages that the shock absorption can be effectively realized during the drilling, the stability of a guide mechanism is improved, the anti-wear element is made of hard alloy steel, the wear resistance is good, in addition, the anti-wear element can be dismounted, and the operation cost can be reduced. The rotary stabilizer can be used for guide drilling operation of ultra-deep wells, horizontal wells and large-displacement wells.
Description
Technical field
The utility model relates to a kind of rotating stabilize with damping effect, belongs to oil and gas well drilling equipment field.
Background technology
Along with each elephant gets into development late stage in succession, the drilling technique of ultradeep well, horizontal well and extended reach well is badly in need of obtaining breakthrough and perfect, especially the steerable drilling technology.A kind of rotating stabilize commonly used in steerable drilling mechanism, this rotating stabilize is connected with the not rotating mechanism that electronic component is housed.Rotating stabilize directly contacts with the borehole wall when steerable drilling; Produce contact friction with the borehole wall; Because near drill bit, so receive strong vibration effect simultaneously, the unstability of the loosening and guiding mechanism of electronic component in the not rotating mechanism that this vibration is prone to cause linking to each other with stabilizer; The meeting of contact friction simultaneously causes the wearing and tearing of rotating stabilize, even loses efficacy.How existing rotating stabilize does not have damping effect and is monolithic, when wear-resistant wearing and tearing, just needs to change whole rotating stabilize.
Summary of the invention
The utility model purpose is in order to overcome the deficiency of prior art, a kind of rotating stabilize with damping effect to be provided, and can guarantee centralizer body with the live spindle rotation, can play good set upright, stabilization.
The technical scheme that the utility model adopts is:
A kind of rotating stabilize with damping effect of the utility model mainly comprises centralizer body, helixseal, rubber sleeve and wear-resistant, and said wear-resistant is fastened on the centralizer body through screw with rubber sleeve; Centralizer body is connected with live spindle through rolling bearing, and is gapped between centralizer body and the live spindle; Said screw shell is through being threaded on the centralizer body; Said helixseal is fixed on the live spindle by holding screw, and rolling bearing is sealed by helixseal and felt sealing ring.
Said wear-resistant is set to 4-10, and wear-resistant material is a hard alloy steel; Said rubber sleeve is cylindric, and the outer wall of rubber sleeve is provided with the axial diversion groove; The outer wall of rubber sleeve has 2-6 radial holes, and the material of rubber sleeve is a polyurethane rubber; Said helixseal bottom is provided with outstanding rib piece.
The utility model advantage is: 1. rubber sleeve effective absorbed oscillation when creeping into, improve the stability of guiding mechanism; 2. wear-resistant is hard alloy steel, and abrasion resistance is good and can dismantle, as weares and teares, and only needs to change wear-resistant, so can reduce operating cost; 3. helixseal is a kind of high-performance dynamic seal, and applicable to the sealing of fluid media (medium) under high temperature, the high pressure, cooperation felt sealing ring can well guarantee the sealing of bearing, the application life that can improve bearing; 4. be matched in clearance between centralizer body and the live spindle, thus can guarantee centralizer body with live spindle rotation, can play good set upright, stabilization; 5. centralizer body end fillet, rubber sleeve end fillet and wear-resistant end ramp structure can effectively prevent load concentration.
