Application Areas

JZ700 Weight Indicating System is an instrument used to record and indicate changes of hookload and weight on bit of drilling tool during well drilling process in petroleum and geological prospecting fields, which can help drillers to judge operation situations of drilling tools and obtain working drilling parameters.

Features     The system is characterized by reasonable structure, easy installation, high accuracy and simple maintenance.

It can meet the requirement of 9000-meter offshore drilling rigs and whose connection parts can be exchanged with weight indicator of other types.
