【摘要】：如何高效地开发储量丰富的稠油资源,一直是油气开采领域的一大课题,对于稠油油藏进行精细地质建模和数值模拟显得尤为重要,其模拟结果过对稠油油藏的开发调整设计具有指导意义。坨7块东一段稠油油藏属于胜利油田,油藏边、底水水体很大,地质情况复杂,开发难度较大。以该区块为研究对象,分析了其地质状况,回顾了其开发历程,归纳了地质特征和开发特征;分析了稠油在多孔介质中的渗流机理、考虑热传递的渗流微分方程,利用数值方法进行求解。在分析研究区块地质特征的基础上,利用静态资料建立了区块的三维地质模型,进一步描述了区块的油水分布、物性参数、断层走向等特征。在地质模型的基础上进行了数值模拟研究,建立了区块静态和动态数据流模型,拟合了区块近20年的生产历史,主要包括地质储量以及产油量、产液量、含水率等主要开发指标,对拟合结果进行了评价。模型建立精度较高,利用此模型对设计的开发调整方案进行预测,预测结果可以进一步指导区块的开发。
[Abstract]:How to develop rich reserves of heavy oil resources efficiently has been a major topic in the field of oil and gas production. It is particularly important to carry out fine geological modeling and numerical simulation for heavy oil reservoirs. The simulation results have guiding significance for the development adjustment and design of heavy oil reservoir. The heavy oil reservoir in the east section of Tuo7 block belongs to Shengli Oilfield. The reservoir edge and bottom water are very large, the geological situation is complex, and the development is difficult. This paper analyzes its geological condition, reviews its development course, induces geological characteristics and development characteristics, analyzes the seepage mechanism of heavy oil in porous media, and gives a differential equation of seepage considering heat transfer. Based on the analysis and study of the geological characteristics of the block, the three-dimensional geological model of the block is established by using static data, and the distribution of oil and water and the physical parameters of the block are further described. Based on the geological model, the static and dynamic data flow models of the blocks are established, and the production history of the blocks in the past 20 years is fitted, which mainly includes geological reserves, oil production, liquid production, etc. The fitting results are evaluated by the main development indexes such as water cut. The model has a high precision. The model can be used to predict the design development adjustment scheme, and the prediction result can further guide the development of the block.
