DS Mop-MWD system is top suspension type. It uses positive pulse mud pressure data transmission, with the unlimited speed of output volume of mud and speed of drilling process, which reduced the limitation and interference of instrument usage at site. The instrument has the advantages of simple structure and convenient maintenance and the pulsars can be maintained and repaired at site. This system is especially suitable for the application of large wellbore directional wells and horizontal wells. DS Mop-MWD system can be easily extended gamma, resistivity, at-bit, pressure parameters and other equipment.
