摘要:
大慶長垣喇薩杏油田隨著聚合物驅油劑的不斷注入,儲層物理性質、流體分布形式等發生了改變,受效儲層的測井響應呈現出復雜的變化。從室內巖石物理實驗入手,分析聚合物溶液本身的導電、聲波傳播特性,模擬油田開發過程,通過水驅、聚合物溶液驅替巖樣的實驗方法,測量驅替過程中巖樣的聲、電、核磁等方面的特性數據。在總結對比分析聚合物驅替巖心的電學、聲學、核磁共振等物理性質的實驗變化規律的基礎上認為,聚合物驅巖心在電性變化上與同礦化度的水驅規律類似,擴散吸附電位有減小趨勢,僅用核磁共振T2譜信息難以識別聚驅是否受效。該研究為聚合物驅后儲層測井評價和剩余油挖潛奠定了基礎。
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.
