The mechanical disconnector
The mechanical disconnector is designed for running and cementing the well casing. When fastening the well casing, it ensures its straightness in the process of wait on cement, thereby preventing unloading on cement stone. The PL-H/MRT disconnector can be equipped keying, that block the premature disconnection from the ranning casing pipes, which allows, in particularly difficult conditions, to perform the tolerance of the liner with rotation. The PL-H/MRT disconnector is used for both vertical and directional wells and is assembled with various technological equipment. Opening of the flushing holes and disconnection is carried out by rotating the allowable tool in the right to the required number of turns.

Design advantages
- the running and fastening of wells in difficult geological conditions;
- with secures control over the cementing process and is given in the high cement sleeve;
- possibility of running and fastening of casing columns without the use hanger for well casing;
- disconnection method with left thread;
- thisis the mentation of sections in a stretched state;
- section casing cementing in tension;
- duplicating option for opening flushing holes;
- constructional options that provide for the possibility of rotation of the section during the descent process.
