Abstract: Parallel reservoir simulation technique was generated to meet the increasing needs of development planning of large-scale reservoir and design of EOR processes.It is growing along with the development of computer hardware.At present,most oilfields in eastern China have successively got into high-water-cut period.In order to find the distribution of the remaining oil,the detailed reservoir simulations are needed,and the accuracy and efficiency of the conventional reservoir simulators need to be improved.Along with the development and ripeness of computer hardware,the speed of a single processor can not be dramaticly increased.Parallel computers with multi-processor have then become main trend of the super-computing industry.Therefore,it is necessary to develop a parallel reservoir simulation software using the new parallel architecture.The basis of the work described in the paper is a 3D,3-phase implicit black oil reservoir simulator named IBO,which has been widely used in many oilfields in China.The authors have paralleled this serial software on the SGI's Power Challenge with 6 cpu's.Series of real field data sets were used to test and evaluate the performance of the parallel software named SPIBO.The paper presents the strategy and programing method of the software realized in a shared memory parallel computer,as well as the results of the test runs.The scale of problems is as large as 470,000 grid blocks.The speed is up to 4 with 6 processors.This achievment brings us the possibility of making large scale detailed reservoir simulation.
