1、Multifunctional mud logging instrument (LH-DGN-I)
1)Product principle
LH-DGN-I multifunctional mud logging instrument is composed of three parts, the instrument room, the geological room and the cable storehouse. there are a gas logging instrument(can be extended to comprehensive mud logging instrument), a geo-chemical logging instrument(includes pyrolysis evaluation、pyrolysis chromatograph、residual carbon analysis) and accessory equipment in the instrument room, there are two fidelity sand dry boxes、a geological fluorometer and geology accessory equipment in the geological room. According to the users' needs, debris image collecting analyzer and fluorescence analyzer can be added.
The instrument integrates the tradition gas-logging instrument room、geo-chemical instrument room and geology room, and it is suitable for the needs of low cost exploration at present.

3)Advantages and characteristics
★Integrates the instrument room and geology room, compact structure
★The sensor signal acquisition and transmission by using CAN bus mode or wireless mode, convenient installation and disassembly, strong scalability
★Continuous analysis of Total hydrocarbon and CO2, thirty seconds rapid analysis of C1-C5 component, avoid the leakage of thin oil and gas reservoirs, and interpret the oil and gas reservoirs based on the data.
★The hardware and software of the instrument are designed according to the model of the comprehensive mud logging unit, if increases the corresponding sensors, it can become a comprehensive mud logging instrument.
★Geo-chemical logging instrument integrates pyrolysis evaluation、pyrolysis chromatograph、residual carbon analysis in a cabinet structure formation, occupy smaller space and easy to use; bottom omni-directional wheel and adjustable foot, make it easy to move and fix.
★The design of two fidelity sand drying boxes and exhaust system, easy to use and improve the work efficiency.
★Sand sample is dried in hot air circulation, the drying temperature is controllable and adjustable. twelve sand samples can be dried at the same time.
★Configuration is flexible according to user needs, debris image collecting analyzer and fluorescence analyzer can be added.
