Special Workover BOP

Product Introduction

Cable BOP

It is mainly used to seal cables in well drilling test, production test, perforation test and production operation test. It adopts round rams, which are featured by small stress and simple structure. These BOPs may be equipped with manual or hydraulic actuator. In terms of structure, they cover five types, namely single ram type, double ram type, triple ram type, manual type and hydraulic controlled type. In terms of upper and bottom connections, they adopt unions or flange structures and the BOPs can be connected to wellhead or other BOPs with the help of cross-over flanges.

Model	Bore Size	Rated Working Pressure
DF65-35	65mm	34.5MPa
DF65-70	65mm	69MPa
DF76-35	76mm	34.5MPa
DF76-70	76mm	69MPa
DF118-35	118mm	34.5MPa
DF118-70	118mm	69MPa

Annular BOP

This type of BOPs is mainly used together with ram BOPS, which was once named as multi-purpose BOP, which means that the BOP may be used to close wells from normal bore size to zero regardless of any shape. The structures include: annular preventers with trunk packing unit, annular preventers with spherical packing unit, annular preventers with tapered packing unit and annular preventers with combined packing unit.
