摘要
盆地含油气区块从勘探评价进入开发阶段,随着产能任务的加大,钻井数量会越来越多,相应地对储层预测精度的要求也越来越高.地震波形指示反演从地震资料出发,以沉积规律和地震地质特征为指导,挖掘相同或相似沉积环境下测井曲线中蕴含的共性结构信息,进行地震先验有限样点模拟,通过蒙特卡罗模拟运算实现对薄储层的量化表征.反演运算过程充分体现了相控思想,较传统方法提高了运算效率和预测精度,可广泛应用于油气藏精细研究、油田开发过程和控制等,有助于最大程度地实现对油藏资源的开发和利用.
When an oil ＆ gas-bearing basin enters development phase from exploration ＆ evaluation phase,more drillings will be deployed as oilfield productivity climbs up. As a result, an increasing demand of the reservoir prediction accuracy will therefore be raised. On the basis of seismic data,guided by sedimentary pattern and seismic-geological characteristics,Seismic Waveform Inversion（ SWI） attempts to find out the similarities of well logs under same or similar depositional environment,then to carry out seismic priori simulation with limited samples,thus,thin reservoir characterization could be quantitatively realized through Monte Carlo simulation. The concept of ＂Facies-Control ＂ is fully employed during the computation progress of SMI. Comparing with conventional inversion methods, SWI improves the computing efficiency and prediction accuracy,and can be widely applied for detailed reservoir study during oilfield development,to maximize the utilization of oil ＆ gas resources.
