  • Api16c High Quality Ram Bop - China

    price: contact company for price

    Blowout preventer is an important component assembly of well

    control device.

    It is characterized by

    flexible switch, easy operation, safety in use and simple

    maintenance, etc.

    Our Bops are designed as

    per the API 16A Specification, with good quality and best

    competitive price.

    Two types of Bop are

    offered by JIELIN: Annular Bop and Ram Bop.

    Ram BOP is an important equipment widely used in onshore and

    offshore drilling.

    Ram BOP, such as

    sing le 「 am BOP, double ram BOP, are mainly hydraulic

    operated or manual operated.

    Ram BOP is

    resistant to high- pressure characteristics is used to

    prevent blowouts safety oilfield sealing wellhead.

    Annular blowout preventer is manipulated by hydraulic

    control system.

    When it is shut off, high pressure oil flows

    into piston underside closed cavity through the oil port in

    central shell, to push piston upwards, and the conical

    surface of piston squeezes rubber core.

    Due to the

    restrictions of head cover, rubber core can’t go upwards

    but is pushed towards the center of wellhead until it

    enclasps drilling tool or enclose wellhead totally to shut

    the well.

    When well needs to be opened, manipulate the

    reversing valve of hydraulic control system, so that high

    pressure oil should flow into the open cavity on top of

    piston through the oil mouth on shell, to push piston

    downwards and decompress closed cavity, in which case, the

    extrusion force on the conical surface of rubber core is

    removed, and the rubber core is reset gradually with the

    action of its own elastic force to open wellhead.

     

    Operating requirements

       

    It’s feasible to control wellhead with annular preventer

    firstly when blowout occurs in a well where there are

    drilling tools, but try not to seal it for long, because

    rubber core is fragile and there is no locking device.

    Don’t close empty well with it in non- special cases.

    It’s necessary to use a drilling tool with an 18- degree

    slope when annular preventer is used for snubbing tripping

    operation.

    Tripping speed should be slow when passing

    through joints, and all the rubber sleeves of the drilling

    tool should be uninstalled.

    When annular preventer is in an off state and shut- in

    pressure is below 5Mpa, it’s feasible to move the drilling

    tool up and down, but don’t rotate it.

    It’s necessary to check whether the well is opened

    completely after it is opened every time lest rubber core be

    scraped.

     

    It’s necessary to wash the inner cavity out to keep the

    switch flexible after well cementation and leaking stoppage,

    etc.

    Be sure to pay special attention to sealing backing ring and

    steel ring groove when installing or uninstalling annular

    preventer, which cannot be cracked up or scratched.

    After entering the target layer, try to shut in the well

    with drilling tool after tripping each time, to check how

    well the rubber core seal the well.

    It should be replaced at

    once if not up to standard.

    Make regular pressure test on the annular preventer

    according to relevant standards.
