Description
casing operation device
(Casing Running Tool) is a mechanical integrated casing tool. The device is installed on the top drive drill pipe joint, and its operation in the clamping and rotation direction is carried out by the driller, and it is controlled to mechanically activate and lose hands. Installation and disassembly is simple and fast, without external pipelines and power sources.

Installation and disassembly is simple and fast, without external pipelines and power sources.
The device can realize the functions of casing suspension, buckling, grouting, circulation and casing rotation, and solve the problem of difficult casing running in complex well conditions.
The clamping and sealing unit can be replaced according to actual needs, and the casing of different sizes and point values can be clamping, so that one machine can be used for multiple purposes.
Functional integration and personnel reduction improve operational efficiency. Personnel remote operation, improve the safety of the operation. Reasonable combination with other tools has brought a new major breakthrough for the casing operation process.
Casing Running Tool with Internal Grip (CRTim)
Tianjin Dongrui Petroleum Machinery Co.,Ltd CRTi is designed for casing drilling or running with top drive equipped rigs to makeup,breakout,reciprocate, rotate,fll, circulate, and cement casing and liner strings,reducing non-productive time andassociated costs. This tool is mechanically activated in tension and both rotational directions solely by topdrive control using TAWG TM(Torque Activated Wedge Grip) technology.
This patented architecture puts control in the hands of the driller, reducing the need for third party supportto run casing. Simple intuitive operating steps for pipe engagement and release closely emulate the famiiar make and break steps used to run drill pipe-stab,rotate to the right to engage and reverse to disengage.Similarly, rig-in and rig-out steps are simple, intuitive and efficient.
Starting from the insertion diameter of the base tool (cage OD), selectable sizes of integral jaws/dies are usedto configure the CRTi to support gripping casing of increasing internal diameter.Through the use of a patentpending extended reach die structure,the gripping dliameter can be further increased to include casing sizes much greater than the base tool.
Improved well construction efficiency relies on the optimization of casing and liner string installation. Offering industry leading capacity with the smallest footprint available for casing running or drilling operations, Dongrui Petroleum Machinery Co.,Ltd’s CRTi® and CRTe® fully mechanical casing running tools with TAWG® wedge grip technology get your string safely to bottom. Mechanical activation by the top drive control to makeup, breakout, reciprocate, rotate, fill, circulate and cement casing and liner strings enables you to remove both personnel and equipment from the rig floor. These tools help avoid instances of stuck pipe, ultimately eliminating extra costs, risks and non-productive time.
