| 摘 要： | 以胜二区沙二段８ 单元为研究对象，建立了该开发单元储层物性和原油物性随不同开发阶段变化的数值模型，并在此基础上进行了精细油藏数值模拟研究。研究结果表明，渗透率、原油粘度和密度随不同开发阶段的变化对剩余油分布和油田开发效果影响均较大。对注水开发历史较长的油田，在进行精细油藏数值模拟时，应该考虑渗透率和原油物性随时间的变化，从而为进入注水开发的老油田的挖潜上产提供可靠的决策依据。通过对８单元的精细油藏模拟，掌握了目前该单元的剩余油分布规律和水淹状况，并成功地指导了该单元开发调整方案的设计和实施

| Abstract: | A model for simulating change of reservoir characteristics and crude properties with the expoitation time in eighth unit of Shengli region 2 is developed. Based on this model the production history of the unit is studied with the fine reservoir simulation. The result shows that variations of permeability and crude viscosity with time have a great influence on the remaining oil distribution and recovery. For the running reservoir simulation on long term water flooding oilfield, the variations of reservoir characteristics and crude properties with developing stages should be considered, so that the decision bases of improving recovery for water flooding oilfield can be proposed. By means of the fine simulation for the reservoir of eighth unit, the present distribution of remaining oil and water out situation are obtained. The research results are successfully applied to design and realization of a plan for improving recovery of the eighth unit. |
