According to the characteristics of development well logging construction, ILS-21 is designed with the purpose of improving the accuracy of oil and gas detection and well control monitoring ability, with the features of infrared gas detection, wireless sensor data collection, overflow and well loss monitoring, to monitor the drilling process in real time, discover oil and gas display, and guide the drilling construction of development well. The equipment is flexible in matching, convenient in function expansion, and has the function of data remote transmission, which can meet the logging service requirements of development well logging, coalbed methane logging and other application fields.
The dual channel non spectroscopic infrared gas detection system has simple structure, which can analyze all hydrocarbons, C1 and C2 +, and accurately analyze methane content under the condition of mixed oil;
Low power wireless sensor data acquisition system, which is convenient to install and use, is suitable for complex well site environment;
It can be equipped with RS-485 data acquisition system, fast chromatograph and other conventional logging equipment to meet different needs;
The early warning system of drilling fluid abnormity adopts mathematical statistical method to analyze data in real time and predict well kick and lost circulation in time;
Well site safety alarm system, automatic multi-level acousto-optic alarm in case of abnormal parameters;
Drilling fluid backflow monitoring function, timely find out the abnormal drilling fluid in the process of single connection and tripping.
