The standpipe pressure sensor can measure the circulating pressure in the drilling mud standpipe in real time, provide the standpipe pressure data to the driller and mud logging personnel, monitor the downhole working conditions, find out the drilling abnormalities in time, and ensure the drilling safety.
Product advantages:
1、One-time installation, maintenance-free, corrosion-resistant; No consumables, no hydraulic pipelines and seals;
2、Excellent accuracy, 2 ~ 10 times that of mechanical sensors, completely eliminating the back pressure effect;
3、Quick response, no hydraulic oil transmission delay, not affected by the reduction of hydraulic oil flow rate caused by low temperature in winter;
4、High cost performance, simple and reliable structure, few parts, easy installation, low replacement frequency, save time and money.
