Feasibility Study on Non-repeating Acquired Time-lapse Seismic Reservoir Monitoring
摘要
Abstract
To study the feasibility of non-repeating acquired time-lapse seismic reservoir monitoring,this paper uses 3-D Gaussian ray-beam forward simulation to simulate and analyze illumination of reservoir,quantifies the impact of different geometry parameters on bin-received energy of reservoir,and finds that the main factors affecting the magnitude and uniformity of bin-received energy of reservoir are distribution of offset and azimuth,namely the magnitude of max-offset and the number of receiver-line. When velocity variation of reservoir has less effect than geometry parameters variation on the magnitude of cell-received energy,it is more necessary to conduct the conforming matching for geometry of time-lapse seismic datasets. The key point in this step should be rebinning and matching of distribution of offset and azimuth in bins. It has proved to be able to efficiently reduce the seismic respond deviation in non-reservoir and amplify it in reservoir by geometry-matching for a set of non-repeating acquired real data from block S56.关键词
