| 摘 要： | 桩西油田中低渗复杂岩性储层岩性差异大，物性差，解堵措施难度大，效果差，介绍了桩西中低渗复杂岩性储层基本特征及敏感性评价，并通过长岩心流动实验模拟研究了优化酸液的解堵性能。在该油田91井次的现场应用表明，有效率73%，对同类储层酸化解堵措施的制定和实施有一定参考意义。

| Abstract: | There is a great difference in lithologic characteristics and the reservoir characteristics become worse and worse in sandstone reservoirs with mid low permeability in Zhuangxi Oilfield. Not only the lithologic characteristics and the potential damage of acidizing are presented in this paper, but also the improvement capability of optimizing acid is researched by the long rock sample flow simulation tests. It provides some references for the design and implementation of the acidification projects. The successful rate of acidizing unplugging wells is visibly improved by field applications in Zhuangxi Oilfield. |
