Abstract: The parallel numerical simulation software is a new technique developed in recent years. It is characterized by either dealing with large-scale and extra-large-scale reservoir numerical simulation,or speeding up calculation of the small-scale simulation, providing greater, quicker and more accurate modeling, shortening cycles for studying. This paper presents the VIP 5.0 introduced in 1999 from Landmark Company, which includes black oil compositional (containing fracture) software packages with eight CPU and accessory software, by which meganode big block oil compositional model can be run. The overall test has been made in solution stability, parallel efficiency, etc. by taking a complex fault-block reservoir in an oilfield of Xinjiang, a carbonate condensate field in abroad and a weak volatile reservoir of Carboniferous in Xinjiang as example. The tested results show that the software can reach stable solution, acer before through aplication in regulatory scheme of a foreign carbonate field contracted by Xinjiang Oilfield Company and in infilling adjustment scheme of Xishanyao reservoir in major regulatory block operated by Xinjiang Oilfield Company. The results provide convenience for in-time working out development regulatory schemes and gain time. It is indicated that all indexes of recommended schemes predicted by VIP sofware are in higher conformity with field conditions during its implementation for one year.
