The Construction Method Research Of Search Engine Base On Federal Model In Oil-ifeld Information

In the period of the construction of the digital oilfield, there is many forms about thedata of exploration and development of oil and gas fields storage media, including web pages,documents, database, etc., it is difficult to let user access to data and operate data. Accordingto this situation, some professional branch has established a variety of search engines in theoil field, which were used to search information in the branch. Because there are differencesin the search engine which used by all the branch, including time and space, so the unifiedsystem in oilfield internal was not formed, when people want to find information, they oftendo not know which search engine system can be used to access, as the result, the problem isappeared about search engine integration. The face of the characteristics of autonomous anddistribution in different information systems of the various business units, it is become anecessity demand which we unified manager of oilfield information search engine.At first, this paper analyzes the problems of the current centralized model oilfieldinformation search engine applications in large scale, using the distributed technology of theFederal,building the federated search engine which dispersion on logic, and studying thefederated of the type of node, and the node distribution, as well as federal search enginearchitecture. This paper focuses on how to ensure the performance of the system does notdepend on the hardware, and integrates oilfield information search engine which scatters inall branches of the oil fields and the structure of different into federated model, and propose aunified integrated standard for oilfield companies,using the Web Service technology, achievesthe oilfield information search engine integrated. Finally, using federal distributed andmeta-search engine technology, analyzing the structure of oilfield information, according tothe difference of the oil-field information and Internet information, and combining thesecurity control mechanism of the oilfield internal information, raising an improved summaryalgorithm of meta-search engine base on user identity and personality preferences, achievedthe results sorting strategy in the oil fields.
