[China Instrument Network Instrument Development] On January 2, LJ-MPS-I multi-parameter integrated sensor for drilling fluid independently developed by Bohai Drilling & Logging Co., Ltd. won a national utility model patent and had completely independent intellectual property rights.

At present, domestic integrated logging units use three sensors, density, conductivity, and temperature at the entrance and exit. The total weight of the sensor is 55 kg. It is also necessary to avoid equipment such as stirrers in the mud tank. Extremely inconvenient.
Compared with traditional sensors, the new sensor integrates the above three types of sensors to continuously detect drilling fluid density, drilling fluid conductivity, drilling fluid temperature, and integrate these three parameters through integrated probes and integrated transmitter units. It becomes a 4-20mA signal to the logging tool.
The sensor weighs only 15 kilograms. In a single person's situation, the sensor can be installed in one hour, which greatly facilitates the dismantlement and maintenance of the site. At the same time, the sensor has obvious cost advantages. Each unit can save 2,000 yuan more than the original equipment and is suitable for different construction work areas.
