BJZZ series weight indicator is suitable for drilling and workover operations in petroleum and geological exploration, and is used to indicate and record the weight of drilling tools and the change of WOB in real time. The instrument is the core instrument to assist the driller to control the drilling parameters and judge the working state and potential abnormalities of the downhole drilling tools.
Advantages of the product
• Pure hydraulic mechanical structure, no external power supply, no circuit components, no risk of electric spark, suitable for explosion-proof operation scenarios;
• Simple structure, easy operation, intuitive dial display, easy for driller to quickly read and judge weight data。
