Description
Technical field:
The utility model relates to a kind of workover treatment quick change ram preventer, and particularly suitable needs the frequent workover treatment of changing the tapered tubing string oil well of flashboard.
Background technology:
Along with the development of petroleum drilling technology, deep-well, ultradeep well get more and more, and the oil well ratio of combined string rises significantly, according to the polytechnic demand of workover treatment, tubing string is made up of the oil pipe of plurality of specifications, and promptly larger-diameter oil pipe is adopted on top, and the oil pipe of minor diameter is adopted in the bottom.The ram preventer housing that uses adopts the 8-10 bolts to be connected with side door at present, field stripping, and erection bolt is hard; And the sealing of housing and side door employing end face seal, the weight of side door is very big, changes the flashboard difficulty, wastes time and energy, and has increased the time and the labour intensity of supplement production, has reduced the operating efficiency of workover treatment.
Summary of the invention:
The purpose of this utility model be to provide a kind of on-the-spot change flashboard convenient, fast, save time, the workover treatment quick change ram preventer of laborsaving suitable composite oil pipe tubing string.
The utility model is achieved in that this quick change ram preventer, and it is made up of housing, flashboard assembly, flashboard axis, side door, bearing box assembly, sealing ring, its side door is a T type structure, the sealed end that side door matches with the housing side window is rectangular round end structure, the sealed end periphery is equipped with sealing ring, the side door other end is a cylindrical structure, side door is fixed on the housing by T type baffle plate, T type baffle plate is by the baffle plate screw, T type baffle plate is an opposite opened, and the opening and closing part is divided into semi-circular and matches with the side door cylindrical portions may.During workover treatment, when needs are changed the flashboard assembly, on housing, unload the lower baffle plate screw, in the T-slot of housing, extract two T type baffle plates of splitting out, embrace the bearing box assembly, integral body is extracted side door, flashboard axis, flashboard assembly, unload the lower flashboard assembly from flashboard axis, replace with the flashboard assembly that needs, make the diameter of tubing string identical, then flashboard assembly, flashboard axis, side door are inserted in the housing, T type baffle plate is inserted in the T-slot of housing with the diameter of flashboard assembly, with the baffle plate screw T type baffle plate is fixed, thereby realized the on-the-spot flashboard of changing fast.
The utility model saves the assembling-disassembling bolt time because side door and housing adopt the connected mode of T shape, and on-the-spot replacing flashboard is convenient and swift, has improved the operating efficiency of workover treatment, has won the time for preventing blowout, reduces gas blowout accident.
