Product Description

Ring BOP
  Brief of Ring BOP  
1. Role

In supporting the use of hydraulic control system, when a drill hole, closed to the annular space of different sizes; when no drill hole, totally closed wellhead. Here a coring, logging operations when the WBC, the drill pipe can be closed, coring tools, cable, wire rope, and other shaft formed annular space. In decompression Pressure Regulating Valve and buffer storage device support, through small study of 18 degrees without deduction welded drill pipe, forced from the drilling operations.

2. The operating principle of annular BOP

Ring BOP manipulated by hydraulic control system. The closure, the central high-pressure oil from Shell Oil closed lower part of the mouth cavity enter Detroit, the Pistons uplink promote Pistons conical extrusion plastic core. Because of the restrictions roof, plastic-not only pushed up to the wellhead cen
ters untilæ±ç´§drill or completely closed wellhead, and realize itså°äºpurposes.

When the need for open wells, the hydraulic control valve control system, high pressure oil from the Shellä¸æ²¹I opened the top of the piston into the cavity to promote Detroit downlink, closed cavity pressure relief, the role of core-cone in the plastic extrusion pressure elimination of flexible plastic core force in itself gradually reposition and opened wellhead.

3. Application requirements

(1) in a drill hole when the blowout occurred, to use Central BOP control wellhead, but try not to be closed for a long time, a plastic core easily damaged, the no locking device. Non-exceptional circumstances, not using it closed empty wells.
