Development Of Common Data Acquisition Module Of Comprehensive Mud Logging Unit

Comprehensive mud logging unit is a sort of engineer monitor and data acquisition system which assembles geologic logging, drilling engineer and information evaluating. Data acquisition module is the core and is the only resource of the original rig data. At present, there are many sorts of comprehensive mud logging units and many conflicts in standard and matching. This not only brings complex, but also leads to education difficulty and service costly.In order to meet the standard requirements and realize open sharing of data, a comprehensive mud logging technology is put forward. The research includes:(1)The mainstream comprehensive units, such as Advantage and ALS series, are studied. After having analyzing the data transmission model and processing methods, the soft and hard interface technology and realizing method is grasped.(2)Common Acquisition Module (CAM) is researched and developed. This module offers data to the mainstream comprehensive units as a standard data resource. The destination is to realize the technology matching between CAM and different comprehensive units and achieve the simplicity and currency of the key modules.The research production, CAM, has been experimented on mainstream comprehensive units. The effect has proved that the CAM meets the requirement of the logging mission. It can reach or superior to the properties of the original logging modules. The CAM is worth of being popularized.
