Product Information

I. Application: JZ series indicator is a kind of instrument used to indicate and record the suspended weight and weight-on-bit change of drilling tools during petroleum and geological exploration (repair) well operations. Repair) working parameters in well operations and judge the working status of drilling tools. Features: 1. JZ series finger weight performance has 14 specifications and 23 types for selection of different types of drilling (workover) rigs. The finger weight gauge consists of a dead rope holder, weight indicator and recorder. The dead rope holder can be divided into two types: horizontal and vertical according to the installation method. 2. High precision and reliable performance of the instrument. 3. Good anti-corrosion performance. It is suitable for domestic use and can meet the requirements of foreign users. 5. The pipeline joint adopts fast and self-sealing joints, and the pipelines are connected quickly, easily and reliably. 6. The ink of the recorder records the working curve, which is convenient for establishing drilling work files.
