Design And Research About Well Logging Database Based On Oracle

At the present time, Liao He Oilfield Well Logging Co. attains a great amount data of well logging. But it is not convenient to gather the data because of lacking of effective management of data. And it has wasted much human power and material resources. Meanwhile much of these data has been destroyed which does not work on well logging effectively. Each oilfield has its own character respectively because of the complicated geological situation. For the sake of providing necessary data for production in different period, we need to retain these integrated data of well logging by creating an integrated database. Nowadays, no oilfield co. attains an integrated database for well logging yet. It would have affected the well logging market deeply if Liao He Well Logging Co. could create it.The essay has discussed the issue of the classified management in oilfield database system and effective management of various data according to the requirement of . After considering the effect ion of earth physical data to the system, it has created the database system structure according with the practical situation in the Co. The system has guaranteed both the data kept safely and selected quickly from multi-angles. These above are my main task in this project.Above all, it should classify the type in oilfield database structure clearly form analyzing much data of well logging. I have classified these well logging data into various types: basic information configuration, basic information of...
