HWDP(Heavy Weight Drill Pipe) Description: Heavy weight drill pipe is the most commonly used in the vertical section of the hole and provides weight on the bit for directional drilling while maintaining more flexibility than a drill collar.Heavy weight drill pipe has a "center upset", also known as wear pad, that increases tube...

RTTS Circulating Valve RTTS Circulating valve is a locked-open/locked-closed valve that serves for opening and closing holes. The valve can not only be used as a circulating valve, but also as a bypass valve. This kind of the circulating valve is designed for using with multifunctional packer. Technical parameters ...

RTTS Packer RTTS packer is a large bore and mechanical set hookwall packer which can pack off bi-directional pressure. RTTS packer is designed for formation testing, acidizing, cementing plugs and other operations. RTTS packer could perform a variety of functional jobs in one-time descenting down hole.  Technical...

RD sampler It is a full bore sampler which is used in cased hole and is operated by annulus pressure. It is mainly used in the full bore formation testing job to get the formation fluid sample under downhole pressure state. The entire test tube string is kept full bore status before and after sampling and does not affect the conduct of...

Hydraulic Circulating Valve Hydraulic Circulating Valve is a FUL-FLO circulating tool. It can be connected above or below the tester. When connected below the tester, hydraulic circulating valve is used as a bypass of packer. This can reduce the tool from drilling and suction effect of descenting down hole. When connected above the...

Kill manifoldDescription:In case of increase of the well head pressure, kill manifold can provide a means of pumping heavy drilling fluid into the well to balance bottom hole pressure so that well kick and blowout can be prevented. In this case, by using blowdown lines connected to the kill manifold, the increasing well head pressure also can be...
