河流相储层开发初期地质建模
|
摘要
针对河流相储层横向分布不稳定、开发初期钻井资料有限等情况,提出一种在地震反演波阻抗资料约束下,综合应用钻井和测井数据,并结合储层地质建模技术,进行河流相地质建模的方法。通过BZ3-2油田三维地质建模的研究,认为在此思路指导下建立的河流相储层开发初期储层定量地质模型,为河流相储层开发方案设计提供了合理的地质依据,从而降低了油田的开发风险。
Aimed at the complicated geological characteristics of fluvial reservoir in Bohai Bay and the limited well logging data in the initial stage of the reservoir development, a method of fluvial reservoir modeling is proposed. Well drilling and logging data combining with geological modeling techniques are applied to perform the geological modeling of fluvial reservoir under the impedance constrained inversion. Taking the geologic modeling in BZ3-2 Oilfield in Bohai Bay as an example, the result shows that the quantitative geologic modeling of fluvial reservoir established under the guidance of this method provides a reasonable geology criterion for the exploration of fluvial reservoir and decreases the development risk.
