摘要:
大庆长垣喇萨杏油田随着聚合物驱油剂的不断注入,储层物理性质、流体分布形式等发生了改变,受效储层的测井响应呈现出复杂的变化。从室内岩石物理实验入手,分析聚合物溶液本身的导电、声波传播特性,模拟油田开发过程,通过水驱、聚合物溶液驱替岩样的实验方法,测量驱替过程中岩样的声、电、核磁等方面的特性数据。在总结对比分析聚合物驱替岩心的电学、声学、核磁共振等物理性质的实验变化规律的基础上认为,聚合物驱岩心在电性变化上与同矿化度的水驱规律类似,扩散吸附电位有减小趋势,仅用核磁共振T2谱信息难以识别聚驱是否受效。该研究为聚合物驱后储层测井评价和剩余油挖潜奠定了基础。
Abstract:
After many years’ developments, La,Sa & Xin oilfields in Daqing placanticline have entered into extra high water cut stage. Polymer flooding has been widely applied in the fields. Along with polymer agent injection, physical properties and fluids distribution of reservoirs have changed. To recognize the changes of logging curves in polymer flooding reservoirs, the indoor reservoir petrophysical experiments have been made to systemically analyze the polymer solution characteristics of conductivity and the sound propagation. Electricity, acoustics, nuclear magnetic resonance parameters of the core samples are measured with the water and polymer flooding core samples tests. Results suggest that the polymer flooded cores are similar to the water flooded cores with the same salinity in the changes of electrical properties, and the diffusionadsorption electric potential trends to decrease, so it is difficult to use nuclear magnetic resonance T2 spectrum to identify the polymer flooding effectiveness. This study lays a foundation for establishing identifying standard of flooding degree and calculating parameters in polymer flooding reservoirs.
