阿南油田阿11断块AI上油组周期注水动态参数优化

Optimization of Periodic-Waterflooding Dynamic-Parameters for A-11 Block AIupper Oil Measures at Anan Oil-field

阿南油田构造复杂 ,非均质性较强 ,是典型的低渗透砂岩油田 ,稳定注水开发存在油产量低、采出程度低、稳产难度大三大矛盾 ,为了提高阿南油田低渗透砂岩油藏的动用程度 ,提高油田产油量 ,降低含水率 ,为下一步新区块投入开发及油田注水开发调整提供依据 ,以阿 11断块的阿 11- 30 4井组 (其开发层位是A上I 油组 )为研究对象 ,充分利用井组内及邻近区域内井的油藏精细描述静态资料和井组内注采井的动态资料 ,参考注采井的产吸剖面资料 ,在优化了该井组周期注水的方式的基础上 ,应用油藏数值模拟技术研究了周期注水的注水量、周期和时机对周期注水效果的影响 ,优化了阿南低渗透砂岩油藏的周期注水参数。

For increasing oil recovery and decreasing water-cut of Anan low-permeability reservoir,taking A11-104 well group as an example, with full consideration of reservoir description results and dynamical data,on the basis of selection of Periodic-Waterflooding Pattern,Optimization of Periodic-Waterflooding Dynamic-Parameters for A-11 Block AIupper Oil Measures at Anan Oil-field has been done by reservoir numerical simulation.It includes water injection rate,period and when.
