表面活性剂洗油酸化工艺在特低渗透油藏的应用

Application of surface active agent to press to increase to note craft for especially low permeate oil hides

由于特低渗透油藏存在启动压力高和渗透低的特点,酸化有效期比较短,酸化难度很大。通过对表面活性剂洗油酸化机理的分析,并在江家店油田的试验应用取得的较好酸化效果。

Because of especially low permeate oil to hide an existence start pressure high with permeate a low characteristics, increase to note term of validity shorter, increase to note a difficulty very big. Pass a live the analysis that decline to press to increase to note mechanism is to the surface, and obtain more at the on trial application of store oil - field in river＇s house increase to note effect, at especially low the live permeating oil to hide to apply surface increase to note a craft to have better expansion prospect.
