数值模拟技术在中亚KALAMKAS油田的运用

APPLICATION OF NUMERICAL SIMULATION TECHNOLOGY ON KALAMKAS OILFIELD IN CENTRAL ASIA

本文利用ECLIPSE数值模拟软件对卡拉姆卡斯油田Ю-Ⅰ、Ю-Ⅱ、Ю-Ⅲ三个砂岩组开展了数值模拟工作。地质模型使用Petrel建模软件建立的变饱和度精细地质模型,包括构造模型、沉积相模型及属性模型;根据历史生产资料建立动态模型;应用ECLIPSE数值模拟软件对区块地质储量及各小层地质储量进行拟合,并结合油水井生产动态数据进行水驱历史拟合。根据拟合结果可以看出,无论是区块总体指标还是单井指标都控制在相对误差范围内,达到了很好的一致性,能够真实地再现油藏的开发历程,为后期开展方案指标预测奠定良好基础。

In this paper,ECLIPSE numerical simulation software is used to simulate the work of IO-I,IO-Ⅱ,IO-Ⅲ three sandstone groups in KALAMKAS oilfield.The fine variable saturation geological models,which are established with Petrel modeling software,include the structure model,the sedimentary facics model and property model.The dynamic model is set up based on historical production data.ECLIPSE numerical simulation software is used to fit geological reserves and the small layer geological reserves in the block,and history match of water flooding is made based on the dynamic data production in oil and water wells.According to the matching results,cither block or single well overall target indicators are controlled within the range of relative error,achieving a good consistency.It can veritably reappear the course of oilfield development and lay the foundation of numerical simulation on indicators forecast later.
