| Being a systematic engineering of high technology, high complexity and innovation, CCSD project includes the items of complete coring of 5000 m drilled in hard crystalline rocks, well-logging, geo-logging, geophysical remote sensing, on-site analysis, drilling information management system, long-term observation laboratory and multi-disciplinary research. The drilling project is an important part of CCSD. There is a lot of information about drilling to be collected and dealt with. Those disposed data will be shared in local network, which provide drill-expert and technicians with necessary information and helps them to manage production on spot. Because CCSD is a great national project, it needs far higher quality of collecting and dealing drill data than any of exploratory oil wells or any of exploratory geological boreholes. It is necessary to construct the drilling project network database of CCSD to manage collected data and information about drilling, with a set of querying interfaces which is convenient for querying and a set of inputting interface which is simple and visual. In the demand of the leaders of CCSD command, I myself developed the drilling project network database of CCSD on the base of adopting a lot of advice of drill expert and technicians about dealing with data, Which solves the problem of dealing with drill data and quickly query data in the network, So it has good serviceability in the exploration drilling. The functions of the network database are as follow:(l)The network database can provide the function of querying the cases of service and the result of data statistics about common drilling tools such as diamond bits, reamers, hydro-hammer -s, Navi-Motor and shock absorbers. We can know detail cases of the tools services through the network database such as run, initial depth, final depth, core Length, Working time, recovery, working efficiency . We can also know the cases of the data statistics by the network database such as total core length, total working time, average working efficiency, service time.(2)The network database provides querying surface and inputting surface of the bit card. (3)I have developed querying surface and inputting surface of real time drilling parameter. The head and bottom of the querying surface is fixed. We can run over the middle data of the querying surface by rolling mouse in addition, we can query former drilling parameters in the term of run by rolling mouse. By the way the data of the querying surface is refreshed at interval, which makes drill technicians know timely drilling parameters on spot. Because the inputting surface is made of Excel component, its form likes Excel's and it has main functions of Excel, it is very much convenient for us to input data in the inputting surface.(4)There are mud report and drilling report in the network database. The form of Its' querying surface and inputting surface likes Excel's. We can query previous mud performance according to date and class by rolling mouse.(5)There is construct efficiency report in the network database. It is easy for us to query the statistics of construct efficiency by month.(6)There are querying surface and inputting surface of logging data in the network database. To introduce the process of realizing the functions of the network database, this article is divided into five charters. The first charter is introduction. In the first place, the introduction tells us the current situation of the world continental scientific drill. Secondly the introduction tells us the current situation, aim and mean of CCSD. Finally the introduction tells us the aim and mean of the drilling project network database of CCSD. The main content of the second charter is the design of the drilling project network database of CCSD. In the first place, the charter discusses the whole design of the drilling project network database of CCSD, then the data and information of CCSD is given demand analysis which is on the base of advice of the experts on spot. Then the technique design, physical...
