油田开发初期建模策略研究

MODELING STRATEGY STUDY IN OILFIELD EARLY DEVELOPMENT PERIOD

储层建模是油田开发的基础和关键技术之一,但其可靠性在钻井少,处于开发初期的油田却遇到了挑战。鉴于此,提出在地质概念模型的指导下,多学科综合,应用随机模拟理论,多种数据集成进行建模的策略。并以苏丹FL油田为例,采用随机地震反演-随机建模一体化技术,充分利用地震波阻抗数据体进行约束建立相模型及相控储层参数模型,大大降低了井间储层预测的不确定性。

Reservoir modeling is one of the most fundamental and crucial techniques for field development. But its reliability is often challenged in oilfield early development period with very few wells. This paper has put forward a modeling strategy on the basis of geological concept, stochastic simulation theories, and various kinds of data to build a reasonable reservoir model. Taking Sudan FL oilfield as example, this integrated seismic inversion and stochastic modeling method were adopted to build facies model and facies-controlled petrophysical model by using seismic impedance data, thus the indeterminateness of inter-well reservoir prediction could be greatly decreased.
