摘　　要：针对裂缝型油藏冻胶体系调剖模拟表征评价难的问题,结合渗流理论、室内实验及工艺方法,以eclipse油藏数值模拟软件的聚合物驱油模块为平台,建立了冻胶体系成胶反应流体增粘改善水油流度比特性的调剖模拟表征方法,建立了体系对储层影响及体系对生产影响的措施评价方法,并将以上方法应用于海上某高含水期潜山油藏,结果表明,该方法可快速等效实现调剖体系改善水油流度比、降低裂缝水驱能力特征的模拟,模拟结果与措施预期效果具备较高的一致性。In view of the difficulty in profile control simulation and evaluation of gel plugging agent system for dual-media fractured reservoir,the study combines percolation theory,lab experiments and process methods,taking the polymer flooding module of reservoir numerical simulation software eclipse as the platform,the study establishes the profile control simulation method of increasing water viscosity and improving the fluidity ratio of water and oil via the gel-forming reaction,and the evaluation method of the influence of the system orreservoir and production is also established.The established methods are applied to an offshore oilfield,which is a high water-cut buried hill reservoir with the aevelopment of fractures.Results show that this method can efficiently and equivalently realize the simulation of mechanism on profiling system to improve the fluidity ratio of water&oil and reduce fracture water flooding capacity.The simulation results have good consistency with expected effect of the measures.
