Research On Interaction Adjustment Technology Of Reservoir Model Controlled By Seismic And Dynamic Data

After long period efforts, reservoir prediction and description of sandstone in Bohai Sea has made great progress, and at the same time , reservoir numerical simulation has also become conventional oil field development tool. However, the results of reservoir description can not be effectively used for numerical reservoir simulation, and dynamic data of field development can not come back to test and modify the results of reservoir description. Thus, a system that could integrate two techniques and related research on interaction adjustment technology of reservoir model controlled by seismic and dynamic data is needed. It will improve the efficiency and the level of research of Bohai oil field.Some of the main elements of this paper: The seismic forward of rock physics model and numerical model based on synthetic seismic response; established target function with weight and formed double constraint reservoir model of seismic and dynamic data . This model can make rock physics model scale each other , study effect degree of all kinds of parameter to seismic response, including rock parameter , property parameter , dynamic parameter , modify reservoir model and observation contrast between synthetic seismic data and real seismic data on time . This paper developed the practical application of interaction and automatic iteration. Through the research and application of this technology, it will provide a more accurate guide for remaining oil distribution forecast of developed oil fields, oil field adjustment programs and adjustment wells arrangement.
