The development of modern comprehensive logging instrument and integrated applications of logging information

A comprehensive logging instrument is an essential large-scale intelligent instrument in oil drilling operations. Using the computer´s serial communication interface, the instrument´s interface equipment mainly consists of an integrated microprocessor-based smart module and controlled by the host computer. It records data from many projects in oil drilling operations as well as geological parameters, and makes intelligent processing. The results obtained from the on-site drilling monitoring and comprehensive logging instrument off can be used to guide proper drilling operations and, ultimately, to gain reservoir information. The well site data are transferred, via GPRS (General Packet Radio Service) or CDMA network to the base server, so as to realize the intranet connection between data center and the base of the well site, and synchronize database at the base information center e with those at the well site The base clients can choose a one-site wells historical data or current data to view, including data tables and view while browsing broken curve, and they can view on the LAN in the real-time, so as to provide rapid decision-making for the base. In addition, comprehensive comparative analysis can be conducted based on the monitoring data from multiple well fields in a region. The development and implementation of this system in a number of oil fields has been unanimously accepted.
