SK-CMS Comprehensive Mud Logging Unit

SK-CMS comprehensive mud logging instrument has been widely recognized by mud loggers. It not only serves major domestic oil fields, but also goes abroad to serve more than ten countries and regions such as the United States, Russia, India, Pakistan, etc., becoming a real national brand.

Instrument Features

Differential chromatography: solves the problem of identifying true and false oil and gas displays caused by oil mixing, addition of organic additives and drilling fluid pollution.
Explosion-proof CAN bus transmission: simplifies sensor installation, easy expansion, automatic fault diagnosis, and self-protection.
Remote transmission: realizes real-time information transmission between the well site and the remote base regardless of the communication method.
Dual-machine hot backup: adds double insurance to ensure the normal operation of logging work and data security.
Well site information center: open database structure and WITS standard interface to achieve integration with third-party data.
Paperless records: realize paperless records and logging process reproduction that cannot be modified in the whole process, and can directly generate PDF documents.
Professional abnormal warning: engineering abnormality prediction expert system can reduce the occurrence of engineering accidents, greatly reduce operational risks, and ensure the safety of drilling construction.
Comprehensive evaluation of oil and gas: integrates various information such as engineering, gas measurement, geological analysis, etc., greatly improving the interpretation and evaluation compliance rate of oil, gas and water layers.
Rich application software has withstood international tests - Chinese, English and Russian versions meet international service needs.
