平湖油气田精细地质建模方法

Fine geological modeling of Pinghu oilfield

平湖油气田是一个构造简单、边底水活跃的岩性-构造油气藏,主要含油气层系为古近系花港组和平湖组,目前油田已经进入高含水开发后期.本文首先应用Gmax、Earthvision和Petrel软件联合反演,进行储层的精细地质建模,然后利用钻井资料强制约束、地震属性体进行适当约束模型,充分考虑了地震、测井、储层物性等多种地质属性,实现了确定性与随机性建模技术的有机结合,大幅度地提高了地质建模精度.

Pinghu oil and gas field is a lithology-structural reservoir with simple structure, active bottom and edge water, the main oil-bearing layers are Huagang and Pinghu group of Paleogene. The current field has entered a post-high water cut stage. Using Gmax, Earthvision and Petrel software, a joint operation is carried out for detailed geological reservoir modeling. Using drilling data as mandatory binding, seismic attribute as appropriate constraint for modeling, seismic, well logging, reservoir properties and many other geological properties are fully considered in modeling, with the uncertainty and combination of random and organic modeling techniques, the geological modeling accuracy is substantially improved
