油藏数值模拟技术在海上油(气)田开发中的作用

Application of reservoir simulation technology to offshore oilfield development

油藏数值模拟技术在我国运用已久,但其在油(气)田开发中的作用一直以来存在争议。相对于陆上油田开发,海洋油田的开发具有投资大、风险高、钻井少、资料数据相对有限的特点。通过多年利用包括油藏数值模拟方法在内的多种油藏工程方法进行海上油(气)田整体开发方案研究、开发方案调整研究、动态跟踪研究、剩余油(气)分布研究以及参与储量计算、储量评价、三维地质建模等工作,客观评价和归纳了油藏数值模拟技术在海上油(气)田开发中的作用以及多年来运用油藏数值模拟技术的几点体会。

Reservoir simulation technology has been widely used for a long time in China. Compared with onshore oilfield, offshore oilfield development has its own special characteristics such as capital intensive, high risk, and limited drilling information. So its development strategy is different with conventional onshore oilfield development. Reservoir simulation technology can be used to study overall development scheme, development scheme adjustment, dynamic follow-up, and remaining oil distribution, and it also can be used to calculate and estimate reserves and set up 3D models. Application and effects of reservoir simulation technology in China was introduced and commented in this paper.
