Geologic modeling technique of oil reservoir based on sedimentary facies control

提出了基于沉积相控制的油藏地质属性模型建立方法,可定量应用精细地质研究成果,建立储层的沉积相分布数字模型,并以此为约束,对储层参数和岩石流体相互作用特性进行井间预测,软件化后形成了具有大庆特色的沉积相控制油藏地质建模技术。这种建模技术免去了其他方法对人工交互的需求,进一步提高了地质模型的可靠性和实用性。通过油田几十个实际区块的建模实践表明,其结果不仅能定量反映地质研究人员的认识,也使接续的剩余油分布研究结果更加准确。

A method of geologic attributes modeling of oil reservoir based on sedimentary facies control is presented, and the digital model of reservoirs＇ sedimentary facies distribution can be established by fine geologic research results. On the basis of the digital model, interwell prediction for interaction between reservoir parameters and rock fluids can be realized. So the geologic modeling technique of oil reservoir controlled by sedimentary facies with Daqing Oilfield features has formed since it is used in software program. This modeling technique does not require any artificial interactivity compared with other methods, so it can greatly enhance the reliability and practicability of geologic model. Modeling .practices for dozens of field blocks have showed that the modeling results not only can quantitatively reflect the understanding of geologic researchers, but also can make the successive remaining oil distribution study more accurate.
