With the development of Internet and information technology, many petroleum data management providers begin to research and develop their own data management platform in succession. Yet few of them pay much attention on the integrating of several services like automatically charging, resource description and searching, load balancing, which hinder the further application of data sharing and app...

The paper describes the theoretical framework and results of using an rapid three-dimensional super element model of oil field development. The model makes it possible to speed up calculation of two-phase filtration in an oil reservoir by hundreds of times owing to the use of large computational cells – super elements, the number of which corresponds to the number of wells in the field. Accurac...

This paper addresses the generation and control of oil droplets in rolling piston type refrigerant compressors at speeds greater than 5000 RPM. This work is part of the development of a variable speed compressor which addresses the problem of critically low oil sump levels that can occur at these extreme speeds. This paper identifies the dominant mechanism of oil droplet generation based on exp...

The paper reviews the notions of expressiveness of description logics from (N. Kurtonina and M. de Rijke. Expressiveness of concept expressions in first-order description logics. Artificial Intelligence, 107:303–333, 1999) and exemplifies their use in the development in Semantic Web languages. The notion of bisimulation—which characterizes the description logic ALC—provides a direct link to wha...

Study on the interlayer has developed associated with in-depth exploration and development of oil fields, which is an indispensable part to characterize reservoir heterogeneity. This study relates to a comprehensive research method of interlayer in rhythmic layering in continental low permeability reservoirs. During the process of waterflooding development, distribution characteristics of inter...
