This has prompted drilling departments to continuously look for ways to reduce their drilling costs and be as efficient as possible. A system called the Drilling Comprehensive Information Management and Application System (DCIMAS) is developed and presented here, with an aim at collecting, storing and making full use of the valuable well data and information relating to all drilling activities and operations. The DCIMAS comprises three main parts, including a data collection and transmission system, a data warehouse (DW) management system, and an integrated platform of core applications. With the support of the application platform, the DW management system is introduced, whereby the operation data are captured at well sites and transmitted electronically to a data warehouse via transmission equipment and ETL (extract, transformation and load) tools. With the high quality of the data guaranteed, our central task is to make the best use of the operation data and information for drilling analysis and to provide further information to guide later production stages. Applications have been developed and integrated on a uniform platform to interface directly with different layers of the multi-tier DW. Now, engineers in every department spend less time on data handling and more time on applying technology in their real work with the system.展开更多

Experimental means such as the water, electricity and gas systems which support the operation of equipment, and multiple sets of engine components （the compressor, the turbine, the combustion chamber, the structural strength etc.） which support the experimental study of the engine also badly needs to improve in the direction of comprehensive monitoring and system integration to meet the needs of high efficient experiment and management. The experiment platform can make the experimental data and the experimental process be shared in different places in real time. Improving the collaborative ability of design and experiment, improving the automatic level of the experiment and so on all need the computer, the network and the professional and matching application system to support so as to guarantee the security, the stability and the reliability of the experiment, and reduce the risk of the experiment.
