    摘要: 岩石物理分析是油藏开发时移地震监测的基础,是连接油藏参数变化和地震响应变化的桥梁。本文以A油田水驱油藏时移地震应用研究为例,系统开展了岩石物理分析在时移地震应用的可行性研究、油藏开发的时移地震响应规律、时移地震油藏参数表征和时移地震综合研究成果解析四个方面的应用研究,结果表明:首先,A油藏流体性质为轻质原油,水驱油表现了较好的岩石物理条件,流体和压力变化是影响油藏开发地层速度和密度变化的主要因素;其次,A油藏具有较好的水驱油时移地震响应特征,弹性参数对水驱油流体变化响应最敏感;另外,油藏开发流体变化和孔隙压力变化对地震响应特征的影响相反,且孔隙度越大,时移地震响应特征越明显。 Rock physical analysis is the basis of time-lapse seismic monitoring for reservoir waterflood de-velopment, which is the bridge connecting variations of reservoir parameters and changes of the seismic response. We make rock physical analysis on reservoir A of waterflooding development, which includes four aspects time-lapse seismic studies on the feasibility, the response characteristics, reservoir parameters characterization and the results interpretation. The study results show that the reservoir A has the good rock physical conditions, and the variation of fluid and pressure are main influence factors on reservoir velocity and density during oil development. Then the time-lapse seismic response features are obvious for reservoir A, and the elastic parameter is the most sensitive for the reservoir fluid variation on water-flooding process. As to time-lapse seismic response, the influences of fluid and pressure are opposite, and the more porosity is, the more obvious is time-lapse seismic response.
