Detailed Product Description

SZJ-1 Multi-parameter Drilling Instrumentation System manufactured by JPIM for various drilling rigs and workover rigs is mainly used to measure and display various engineering parameters as hook load,weight on bit,rotary torque,standpipe pressure,tong torque,  power tong torque, RPM,Pump SPM1#~3#, mud return flow (%), mud pit volume 1#~9# volume, total mud pit volume, total mud in, content of total hydrocarbon and H₂S, height of block, well depth and others during  drilling or workover process.  It can help the driller to judge operation situation of drilling rigs

In computer recording mode, the whole system, including drillers' console, data acquisition unit, computer terminal, software, various sensors, installation cables and hydraulic hoses, can display all the user-customed engineering values at real time on the drillers display console and the computer in the tool pushers office. The drillers console is installed on the rig in the drillers' cabin and the driller can observe the data displayed by hydraulic gauges and LCD display in real time. The data acquisition unit is usually installed in the doghouse for the acquisition and process of different data. DAQ unit is connected with terminal computer in the tool pushers' office. The software runs on Windows operation system, and the data can be displayed in dials, numbers and curves in real time, and they can also be recorded, stored retrieved and transmitted through GPRS/CDMA network. The system also supports certain automatic control of drilling process; provide information and evidence for drilling optimization, troubleshooting and history data for future operation.

When working without computers, the whole system consists of  driller's console, various sensors, cables and hydraulic hoses. Weight on bit, rotary torque, tong torque and standpipe pressure are displayed by gauges in the console, while RPM, pump SPM will be displayed on the sealed low-temperature, backlit, and explosion-proof digital meter.

The recorder of weight indicating system is optional.

Features:

1. Taking advantage of both mechanism and electronics, and employing the world-class    programmed processing technology, the system can group any number of parameters into various instrumentation configurations.

2.  Values of parameters can be recorded, displayed and plotted by the indoor computer system, but also recorded by conventional weight indicator.

3.   Easy and convenient move, installation and uninstallation are guaranteed by special cables that are corrosion-resistant, oil-proof, water-proof, fire-resistant, low temperature resistant and salt-fog resistant, and by the sealed waterproof and explosion-proof aerial connectors;

4.   Adopting electromagnetic shielding technology, it can even work in such adverse environment featuring great environment temperature changes, strong vibration, high humidity and serious electromagnetic interference;

5.  It adopts maintenance-friendly and highly integrated electronic components.

6.  The whole system is explosion-proof;

7.  Easy operation is guaranteed by the flexible software, which realizes switches between Chinese and English, and between metric and British  units.
