Abstract
The utility model relates to an oil-gas well rush blowout control device, and in particular relates to a side shaking type rush blowout control device. The rush blowout control device comprises a telescopic rod assembly, a slip and a diversion pipe slip, wherein the slip and the diversion pipe slip are connected with the telescopic rod assembly. The rush blowout control device is characterized in that the telescopic rod assembly comprises a support rod, a screw rod installed in the inner cavity of the support rod, a sliding casing sleeved outside the support rod; a screw nut is installed at the end part of the sliding casing fixedly; the upper end of the screw rod is in screw-thread fit with the screw nut; the lower end of the screw rod is connected with the inner wall of the support rod through a bearing; a passive bevel gear is connected with the screw rod fixedly; the passive bevel gear is meshed with an active bevel gear installed on the side wall of the support rod; a handle connecting rod is connected with the outer end of the active bevel gear fixedly; the slip is fixedly installed on the outer wall of the support rod; and the diversion pipe slip is installed on the outer wall of the sliding casing fixedly. The side shaking type rush blowout control device is simple in structure and convenient to use; and when blowout happens to an oil-gas well, a blowout preventer can be installed forcibly or a blowout preventer having a fault can be dismantled forcibly so as to install a new blowout preventer through the blowout control device under the condition that the well is under a pressure.
Description
Technical field
The utility model relates to a kind of oil gas well blowout control device, is a kind of side-rock type blowout control device specifically.
Background technology
The oil gas well is when workover treatment, because blowout takes place sometimes in the variation of borehole pressure, if well control device or well control device inefficacy are not installed, blowout will be out of hand, accidents such as the personnel that cause injure, equipment loss, environment pollution.Must there be adaptation to dismantle, install the blowout control device of current well control device by force.Current well control requires when workover treatment, the well control device working preventer to be installed, and this working preventer is double-layer structure at least, the former single layer structure increasing of aspect ratio.The working preventer of being installed if when operation, blowout takes place lost efficacy, and just needed under the situation of blowout, former operation preventer to be pulled down, and the single ram type perventer with steel sealing function is installed by force.
Summary of the invention
The purpose of the utility model provides a kind of side-rock type blowout control device, when oil gas well generation blowout, in well, has under the situation of pressure preventer to be installed by force or to pull down out of order preventer by force with this device and reinstalls preventer.
For achieving the above object, the utility model adopts following technical scheme:
The described side-rock type blowout control device of the utility model comprises the expansion link assembly and is connected slips, the mozzle slips on the expansion link assembly; It is characterized in that: said expansion link assembly comprises support bar, be installed in leading screw in the support bar inner chamber, be sleeved on the sliding sleeve of support bar outside; The end of sliding sleeve is installed with nut; The upper end of leading screw cooperates with nut thread, and the lower end of leading screw is connected with the inwall of support bar through bearing, is fixedly connected with on the leading screw by dynamic bevel gear; Said by dynamic bevel gear and the drive bevel gear engagement that is installed on the support bar sidewall; The outer end of drive bevel gear is fixedly connected with handle and connecting rod, and said slips is fixedly mounted on the outer wall of support bar, and said mozzle slips is fixedly mounted on the outer wall of sliding sleeve.
The upper end of said sliding sleeve is installed with the leading screw safety helmet, and said leading screw safety helmet is a tubular structure.
This side-rock type blowout control device is simple in structure, easy to use, when oil gas well generation blowout, can in well, have under the situation of pressure preventer to be installed by force or to pull down out of order preventer by force with this device and reinstall preventer.
Description of drawings
Fig. 1 is the user mode sketch map of an embodiment of the utility model.
Fig. 2 is the K portion partial enlarged drawing of Fig. 1 embodiment.
The specific embodiment
Like Fig. 1; The described side-rock type blowout control device of the utility model comprises the expansion link assembly and is connected slips 1, the mozzle slips 12 on the expansion link assembly; Said expansion link assembly comprises support bar 5, be installed in leading screw 9 in support bar 5 inner chambers, be sleeved on the sliding sleeve 8 of support bar 5 outsides, and the end of sliding sleeve 8 is installed with nut 10, the upper end of leading screw 9 and nut 10 threaded engagement; The lower end of leading screw 9 is connected with the inwall of support bar 5 through bearing; Be fixedly connected with on the leading screw 9 by dynamic bevel gear 91, said by dynamic bevel gear 91 and drive bevel gear 92 engagements that are installed on support bar 5 sidewalls, the outer end of drive bevel gear 92 is fixedly connected with handle and connecting rod 93; Said slips 1 is fixedly mounted on the outer wall of support bar 5, and said mozzle slips 12 is fixedly mounted on the outer wall of sliding sleeve 8.
The upper end of said sliding sleeve 8 is installed with leading screw safety helmet 11, and said leading screw safety helmet 11 is a tubular structure.
Before the installation, earlier two alignment pins on slips 1 and the mozzle slips 12 are unloaded, make stay pipe 5 and outer hectare of 45 of slips 1 axis.Shift this device onto pithead position, slips 1 be installed on the well head sleeve pipe short circuit 17 of oil gas well, on push away stay pipe 5, make stay pipe 5 axis and well head parallel axes.After loading onto two alignment pins, rotate drive bevel gear 92, sliding sleeve 8 is moved up and down, adpting flange 14 docks with working preventer 15 on the well head; Unload being connected of working preventer 15 and well head 16, shake drive bevel gear 92 then, move on the working preventer, move sliding sleeve 8; Make working preventer 15 depart from well head, unload working preventer 15 backs steel sealing single ram type perventer is installed, move sliding sleeve 8; Single ram type perventer is docked with well head, shake drive bevel gear 92, single ram type perventer is alignd with well head 16; Install the connecting bolt with well head, close single ram type perventer, accomplished the spray work of robbing.Dismantle being connected of single ram type perventer and adpting flange 14, dismantle slips 1, remove this device and get final product.
