Numerical Simulation Reaserch Of Water-injectiong Development Oil Field Of XiQu Zhaike Oil Field

The development of our country low permeability reservoir, especially the long-termdevelopment of Ordos Basin indicates that water injection is a highly effective method toimprove the effect of low permeability oilfield development and enhance the ultimaterecovery of oilfield. Thus, the demonstration of rational flood pattern, infusion parameter andinjection-production pressure system’s confirmation become a critical issue.At present， reservoir numerical simulation is major way to development planoptimization and later development adjustment scheme in many oilfield.The XiQu OilfiedZhaike well area discussed in this paper belongs to low porosity and low permeabilityreservoir, which the general permeability is less than50×10-3μm~2and the average is20×10-3μm~2,the average porosity is10.89%. Besides, in the research area, there are bigdifferences on the well production and most of the wells production decline rapidly. and therehad contradictions and problem in production with the existing development way，therefore，the study of reservoir numerical simulation is very meaningful in the oilfield.On the basis of detailed research of reservoir comprehensive characteristics, the paperestablishes a three-dimensional geological model, and makes the evaluation of developmenttrend and water injection effect. Use of reservoir numerical simulation method,compared tothe demonstration of different injection-production patterns nets,differentinjection-production strength and development layer under the analyse remianing oildistribution,the pressure distribution characteristics of the present well nets and the referencesimilar reservoir development practice.Finally,the paper reach a decision of comprehensivetreatment technology in the oilfield.
