Abstract
A kind of Novel anti-spray plug pressure cap is oilfield blowout prevention technology, which overcomes the shortcoming of current technology, and it is plane above being, suitable for reading is circular; Periphery is equidistant hexagon; The rounded funnel-form of inner face, there is circular hole centre; Above greatly, little below; Six lateral surfaces are all in trapezoidal profile.
Description
Technical field:
The utility model relates to a kind of oilfield blowout prevention technology, especially a kind of Novel anti-spray plug pressure cap.
Background technology:
Originally blowout-preventing choke plug pressure cap is used to balanced well mouth pressure and prevents liquid medium leak device in well.In onsite application, when borehole pressure is too high, need manually to send steel wire, coating lubricating oil at well head, because pressure cap boring ratio steel wire diameter is bigger, coating lubricating oil major part flows to packing box outside, causes operating personnel to smear the time long, under working environment is in high pressure, security risk is large; On when carrying steel wire, steel wire departs from center, pressure cap hole, friction pressure cap, because of lubricating, to steel wire and pressure cap damage greatly.
Summary of the invention:
It is simple that the purpose of this utility model is to provide structure, and easy to operate a kind of Novel anti-spray plug pressure cap, which overcomes the shortcoming of current technology, and the purpose of this utility model is achieved in that above described blowout-preventing choke plug pressure cap to be plane, and suitable for reading is circular; Periphery is equidistant hexagon.
The rounded funnel-form of described blowout-preventing choke plug pressure cap inner face, there is circular hole centre.
Above described blowout-preventing choke plug pressure cap greatly, little below; Six lateral surfaces are all in trapezoidal profile.
Application process of the present utility model is: in hole, pour lubrication oil into, because packing is arranged at bottom, it is slow that lubrication oil infiltrates packing box inside, when steel wire is transferred, lubrication oil can enter in packing box along with steel wire, reduce friction in down stroke, thus shortening post personnel stand in the lubricator time for a long time, greatly reduce security risk; When steel wire is carried, lubrication oil can reduce steel wire and pressure cap hole rubs, extend steel wire and pressure cap application life, and available protecting steel wire and pressure cap, decrease site operation personnel's labour intensity.
Accompanying drawing illustrates:
Fig. 1 is a kind of structural representation of Novel anti-spray plug pressure cap.
Detailed description of the invention:
Be plane above embodiment 1, blowout-preventing choke plug pressure cap described in the utility model, suitable for reading is circular; Periphery is equidistant hexagon.
Embodiment 2, the described rounded funnel-form of blowout-preventing choke plug pressure cap inner face, there is circular hole centre.
Above embodiment 3, described blowout-preventing choke plug pressure cap greatly, little below; Six lateral surfaces are all in trapezoidal profile.
Claims (2)
