Abstract
The invention discloses a rapid well mouth blowout preventing device for oil well sucker rod operation and relates to oil exploitation oil well safety equipment. The device is formed by connecting a rapid plugging valve body and a safety hanger pipe column of a sucker rod to an upper opening of an oil pipe clamp. The upper opening of the oil pipe clamp is connected with a lead-in nipple base through a thread, an upper opening of the lead-in nipple base and a lower opening of the safety hanger pipe column of the sucker rod are connected in an inserted mode and fastened by a pressing cap, an upper opening of the safety hanger pipe column is connected with the rapid plugging valve body in a close fit mode. The rapid blowout preventing device for oil well sucker rod operation is simple in structure, low in manufacturing cost, convenient to install, good in blowout preventing effect, easy to replace, small in operation difficulty and high in safety coefficient and saves time and labor.
Description
Technical field
The present invention relates to oil exploitation oilwell safety equipment, particularly relate to well rod operation wellhead Quick blowout preventer.
Background technology
In petroleum drilling and mining, oil pumper motor-pumped well proportion is larger, when exploration is inaccurate to subsurface pressure test, the mud density injected is too low or when occurring that strata pressure becomes suddenly the situation such as large, often there will be blowout, oil or the gas of ejection cause serious pollution to environment, sometimes be because polished rod break falls or comes off, full well bar is caused to decline, well head packing is in unsealing state, the blowout caused, at this moment need rapidly blowout hookup to be installed, normally used is blowout prevention box, but existing blowout prevention box installation difficulty is large, length consuming time, and complex structure, cost is higher, very inconvenience is installed.
Summary of the invention
The present invention is intended to the deficiency for existing in background technology, and the well rod operation wellhead Quick blowout preventer proposed.
Well rod operation wellhead Quick blowout preventer of the present invention, be by oil pipe pipe collar suitable for reading be connected to sucker rod safe hanging piece tubing string and quick blocking valve body form, the suitable for reading of its oil pipe pipe collar is buckled by spiral shell to be connected to nipple seat, the end opening of the safe hanging piece tubing string of the suitable for reading and sucker rod of nipple seat plugs and fastening by pressure cap, the tight fit connection suitable for reading of safe hanging piece tubing string quick blocking valve body.
As a further improvement on the present invention, the end opening inner ring of safe hanging piece tubing string secures sucker rod suspension bracket, and the end opening of sucker rod suspension bracket to be linked with sucker rod phase spiral shell by pup joint of sucker rod and connects.
As a further improvement on the present invention, the inner ring suitable for reading of pressure cap and the embedded snap ring phase clamping of safe hanging piece tubing string, its end opening coordinates with the phase spiral shell button suitable for reading of nipple seat, and the inserting section of safe hanging piece tubing string and nipple seat has O V-shaped ring.
As a further improvement on the present invention, quick blocking valve body is the radial ball valve of high-speed switch.
As a further improvement on the present invention, the centre bit of sucker rod suspension bracket is the screw be connected with sucker rod upper end, has a vertical passage at least between the periphery of this screw and safe hanging piece pipe string internal wall.
Well rod operation wellhead Quick blowout preventer of the present invention, structure is simple, low cost of manufacture, easy for installation, time saving and energy saving, blowout prevention effect, and change easily, operation easier is little, and safety factor is high.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is that A-A of the present invention is to sectional view.
Detailed description of the invention
Below in conjunction with accompanying drawing 1 and accompanying drawing 2 to well rod operation wellhead Quick blowout preventer of the present invention, be described further.
Well rod operation wellhead Quick blowout preventer of the present invention, be by oil pipe pipe collar 1 suitable for reading be connected to sucker rod 2 safe hanging piece tubing string 3 and quick blocking valve body 4 form, the suitable for reading of its oil pipe pipe collar 1 is buckled by spiral shell to be connected to nipple seat 5, the end opening of the safe hanging piece tubing string 3 of the suitable for reading and sucker rod 2 of nipple seat 5 plugs and fastening by pressure cap 6, the tight fit connection suitable for reading of safe hanging piece tubing string 3 quick blocking valve body 4.The end opening inner ring of safe hanging piece tubing string 3 secures sucker rod suspension bracket 7, and the end opening of sucker rod suspension bracket 7 to be linked with sucker rod 2 phase spiral shell by pup joint of sucker rod 8 and connects.The inner ring suitable for reading of pressure cap 6 and the embedded snap ring 9 phase clamping of safe hanging piece tubing string 3, its end opening coordinates with the phase spiral shell button suitable for reading of nipple seat 5, safe hanging piece tubing string 3 with the inserting section of nipple seat 5 there is O V-shaped ring 10, its object is to after being connected by pressure cap 6, be matched in clearance between safe hanging piece tubing string 3 and nipple seat 5, nipple seat 5 can do free rotation relative to safe hanging piece tubing string 3.Quick blocking valve body 4 is the radial ball valve of high-speed switch.The centre bit of sucker rod suspension bracket 7 is the screws 11 be connected with sucker rod 2 upper end, has a vertical passage 12 at least between the periphery of this screw 11 and safe hanging piece tubing string 3 inwall.
During installation, by quick blocking valve body 4 be high-speed switch radial ball valve on switch opens, oil pipe pipe collar 1 is connected with well mouth of oil well sleeve pipe, in connection procedure, nipple seat 5 can rotate freely relative to safe hanging piece tubing string 3, after connection, ball valve quick blocking valve body 4 is closed and can reach blowout prevention effect.
