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.
As oil and gas blocks in the basin enter the development stage from exploration and evaluation, with the increase of production capacity, the number of drilling wells will be more and more, and the requirements for reservoir prediction accuracy will be higher and higher accordingly. Based on the sedimentary laws and seismic geological features, we excavate the common structural information contained in the logging curves in the same or similar sedimentary environment, carry out the finite-point simulation of the earthquake and realize the optimization of the thin reservoir by the Monte Carlo simulation The inversion calculation process fully embodies the phased control idea, which improves the computational efficiency and prediction accuracy compared with the traditional methods, and can be widely used in the fine study of oil and gas reservoirs, oilfield development process and control, etc., to help to achieve the maximum Development and utilization of reservoir resources.
