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.

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.

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

The parallelization research of the multilayer, twodimension and twophase model used extensivily in Shengli oilfield reservoir simulation is in progress. The two methods of coarse granularity parallel by layers and domain decomposition parallel are put forward and used to realize the software parallelization. The computation of the model and examples showed that multilayer, twodimension and twophase model possesses higher parallel efficiency. In order to solve memory and communication, the technology of compressed memory and compressed communication is adopted, and increases parallel efficiency of software effectively. It provided powerful tool for factor analysis of communication capacity, the number of layer and largescale model use, and for parallelization of largescale reservoir simulation. It also provided technical support for effective spreading fine reservoir simulation technology.

During the middle later development period of an oilfield when reservoir structure and oil water relation have been described clearly, the main task of reservoir description is to build a prediction model of reservoir in order to conduct interwell and beyond well interpolation and extrapolation of reservoir parameters and to refinedly describe reservoir connectivity and petrophysic variability, which can provide a geological base for building a refined reservoir simulation model and describing remaining oil distribution. The AI&N field, Malacca Strait, Indonesia, has been in a high water cut period, where producing wells are relatively less due to higher offshore drilling cost, and using traditional interpolation may be easy to distort heterogeneity of reservoir. This paper has built a geological reservoir model using a geostatistic collocated cokriging technique in combination with drilling, seismic and depositional facies data. This kind of reservoir prediction model is more reasonable than that built by traditional techniques. The production history matches conducted on a reservoir simulation model derived from the geological model indicate that this geological model is more refined, reliable and reasonable. In addition, the geological model quality may be controlled effectively by 3D visualization techniques, and space distribution of reservoir properties can be viewed more intuitively, providing geological evidences for adjustment well design and performance analysis.

油田开发中后期 ,油藏构造及油水关系已基本描述清楚 ,该阶段油藏描述的重点是建立储层预测模型 ,对井点间及以外区域的储层参数作一定精度的内插或外推预测 ,精细描述储层的连通性及储层物性在空间上的变化 ,为建立精细的油藏模拟模型和描述剩余油的分布提供地质基础。印尼马六甲 AI和 N油田已进入高含水期 ,由于海上钻井费用高 ,因此钻井数目不可能象陆地油田那样多 ,如果利用传统的插值方法描述储层属性 ,极易歪曲储层的非均质性。文中把钻井资料、地震信息与沉积相分析结果相结合 ,利用地质统计学中同位协克里金方法建立了储层地质模型。相对于传统的方法而言 ,地质统计学方法建立的储层预测模型更为合理。在储层地质模型的基础上建立了油藏数值模拟模型 ,历史拟合研究表明 ,该地质模型较以往的地质模型更精细、可靠、合理。同时 ,利用三维图形显示技术 ,使地质模型的质量得到了有效控制 ,从而能更真实直观地反映储层属性在三维空间的分布特征 ,为油田调整井设计及生产动态分析提供了重要地质依据
