渤海X油田高精度三维地质建模研究

Research on High-Precision 3D Geological Modeling of Bohai X Oilfield

近年来,渤海油田辫状河三角洲油藏贡献了较大规模的产量,是稳产上产的重要目标。然而海上油田资料匮乏,现有三维地质模型的精度难以满足开发需要,需要新建和补充。为此,采用确定性建模与随机性建模相结合的方式,建立了符合X油田辨状河发育特征的精细三维地质模型。储量拟合结果显示,相对于常规方法此模型的精度可提高10%左右。

In recent years,the braided river delta reservoir of Bohai Oilfield has contributed to a large-scale production and is an important goal for stable production and increased production.However,due to the lack of offshore oilfield data,the accuracy of the existing three-dimensional geological model is difficult to meet the development needs,so it needs to be newly built and supplemented.Combination of deterministic modeling and random modeling is used to establish a fine three-dimensional model that meets the development characteristics of the X oilfield.The results of reserves fitting show that the accuracy of this model can be improved by about 10%compared with the conventional method.
