摘要
时移地震油藏监测可行性分析评价研究能确定对目标油藏进行动态监测的可行性、结果的可靠性,并针对工作中需要处理的技术难题与重点提前设计解决方案。基于实际油田可行性分析评价研究,并结合时移地震油藏监测技术研究现状与发展趋势,从油藏地质条件、储层条件和地震条件3方面出发,利用油藏实际测量数据和模型数据资料,综合分析油藏时移地震监测可行性的系统评价方法,通过岩石物理模型与叠前地震正演的结合进行油藏参数变化定量解释可行性分析评价。可行性研究为时移地震油藏监测研究从叠后地震资料推进到叠前地震资料、提高不同油藏参数解释精度提供了依据。
Feasibility analysis and evaluation technology of time-lapse seismic reservoir monitoring can identify the feasibility of dynamic monitoring and the reliability of result,as well as designing the solution scheme in advance aiming at the technical problems and key points.Based on the feasibility analysis and evaluation for an oilfield,combined with development status and trend of time-lapse seismic reservoir monitoring,the feasibility was evaluated comprehensively in terms of geological conditions,reservoir conditions and seismic conditions by using real field data and modeling data.Meanwhile,rock physics model and pre-stack seismic simulation was combined for quantitative interpretation feasibility analysis and evaluation on the variation of reservoir parameters.The systematic feasibility analysis provides evidences for time-lapse seismic reservoir monitoring research progress from post-stack to pre-stack seismic data,improving interpretation precision,decreasing engineering risk and ensuring the project runs smoothly.
