Abstract: Petroleum pool-forming is complicated processes that includes generating,transportation,accumulation,storage and breaking of petroleum.It is under the control of many geological factors,thus that has relation with center of hydrocarbon-generating,ancient-modern structure,petroleum bearing assemblage,belt of sedimentary facies,property of reservoir rock and its variation.The system of petroleum pool-forming dynamics is the new development of theory of petroleum system and new underway subject.The study of petroleum pool-forming dynamics is based on the support of computer workstation,alternative feedback in study of model and result of simulation reduces fuzzy property of geological interpretation.Thus it is the new supporting system of main technology in geological survey of petroleum.This paper has introduced the development,technological background,principle and simulation system of petroleum pool-forming dynamics.Lastly the prospect for the progress of petroleum accumulation dynamics is put forward.
