Abstract: A two phase «oil-gas» system in local thermodynamic equilibrium is considered. An alternative approach is being developed nowadays to solve compositional models. According to this approach a multicomponent problem is partly separated and the auxiliary problem is formulated in terms of thermodynamic variables. It is shown that the eigenvalues of full problem are expressed through the eigenvalues of auxiliary problem. The technique of hyperbolicity check is developed using the method of auxiliary variable space scanning. Research results can be used in developing of efficient algorithms for compositional problem.

Problems of distributed simulators functioning in secured network segments
Automation, modeling and energy supply in oil and gas sector

Authors: Dmitry G. LEONOV (b. 1970) graduated from the State Academy of Oil and Gas, now Russian State University of Oil and Gas. Cand.Sc. (Eng.), associate professor of Russian State University of Oil and Gas, Automatic Control Systems department. Author of 20 publications in the field of computer simulation of gas transportation systems. E-mail: dl@bugtraq.ru

Abstract: The paper considers different approaches to the task of communication of the distributed simulator components placed in the different secured network segments. Laboriousness and security of possible solutions are estimated. The suggested solution is based on the embedding the internetworking communication mechanism based on the regular polling into the distributed simulator system.

Abstract: In this article basic techniques to automation of drawings production by means of computers were reviewed. The comparative analysis of different approaches to automation was made and its' advantages and disadvantages were disclosed. As the example the program based on one of the studied methods is presented. The program allows to significantly increase the productivity and quality of work thanks to automatic drowning up of the specifications and obtaining of ready-to-use blanks meeting the State standards in AutoCAD file.
